Historical bitcoin price APIs question (taxes)

Just a shout out for help with something I am working on. I am developing a bitcoin tax analysis tool. When it comes to reporting trading fees and account statements, often the values are in BTC. Does anyone know an API to use to get historical BTC price for any given day? AVG value would be great but OHLC will do.
Thank you

How to scrape hourly historical Bitcoin prices to Python using some crypto API??

I am about to make a project on bitcoin, where I analyse how the price movements are affected by Reddit posts and I have two questions:
1) How do I get access to hourly Bitcoin prices over the last couple of months or more? I could scrape daily prices with the Coinmarketcap API, but I was not able to get hourly prices.. 2) I have used the Reddit API for python to scrape posts and comments on Reddit and I seem to only be able to scrape for example the last 1000 posts, and wondered if someone can help me getting access to more posts in a subreddit?

I wrote a python tool to manipulate and visualize the price of bitcoin historically using the coinbase version 1 api.

I know not all of you are programmers, but I tried really hard to make this useable. It's a python tool for price analysis of bitcoin.

Public APIs to download historic Bitcoin candlestick data

Hi Everyone,
I've seen a lot of interest from people in this group to access historical Bitcoin candlestick data. To help everyone out, we've made all of our candlestick data public. That means you can access everything we have here:
https://developers.shrimpy.io/docs/#get-candles
You don't need to sign up for an account or anything. The data is completely public for use. Just call the endpoint in your browser to test like this:
https://dev-api.shrimpy.io/v1/exchanges/binance/candles?quoteTradingSymbol=USDT&baseTradingSymbol=BTC&interval=1H
Try a few different pairs, exchanges, and candlestick sizes - I think you will find it pretty exciting! You can of course plot this data as well. We have some examples of how to plot candlestick data here.
I'm happy to answer any questions if you have some. Looking forward to hearing your feedback!
We also have endpoints for live order book snapshots, market data, trade websockets, and more. You can find our full guide on how to make a crypto trading bot (with all these different data endpoints) here.

Best Cryptocurrency Multi-Exchange Trading and Portfolio Management Platforms Ranking 2020

Best Cryptocurrency Multi-Exchange Trading and Portfolio Management Platforms Ranking 2020
Trade on multiple exchanges from a single platform and avoid the hassle of multiple logins, different interfaces, constant tab changing and overall keeping track of balance holdings and trades.
https://preview.redd.it/ksar6fkxmfv51.jpg?width=1200&format=pjpg&auto=webp&s=b8629b0f29aefd9546d816413cc82de9656ef7f9
With more than 300 cryptocurrency exchanges today, most traders have to manage multiple exchange accounts.
The need for more than one account usually rises because of the variety of offered crypto currency pairs, market liquidity, having to diversify the risk of being hacked, as well as the different trading tools and terms each exchange offers.
Trading and keeping track of your portfolios on multiple exchanges is time consuming, inefficient and frustrating. Having to log on different platforms, use different interfaces, keeping track of multiple portfolios and all trading related activities become increasingly difficult with each new account.
It would be simple and easy if you could connect all those exchange accounts into a single multi-exchange platform which combines all the data in real time and provides a single interface to control all remote exchange accounts.

Multi-exchange platforms

A multi-exchange platform allows the traders to connect all their exchange accounts into a single account through the user of API keys generated from the account of each exchange.
Once all accounts are connected into a single one, using the exchanges interfaces becomes obsolete. The unified account will now track and combine all portfolios and traders will be able to track prices, order statuses and other data across all exchange accounts from a single interface.
In addition, most multi-exchange platforms provide various information tools such as news aggregators, sentiment tools, arbitrage matrix and price alerts.
With regards to API keys security, these platforms do not require withdrawal or deposit permissions which limits the possibility of fraud and loss of funds.
Finally, multi-exchange platforms do not typically charge additional trading fees and do not require lengthy verification procedures.

The current top platforms

Currently there are a handful of multi-exchange platforms with a variety of services. They range from a simple crypto portfolio tracker to an advanced trading and portfolio management platform.

Bob The Magic Custodian



Summary: Everyone knows that when you give your assets to someone else, they always keep them safe. If this is true for individuals, it is certainly true for businesses.
Custodians always tell the truth and manage funds properly. They won't have any interest in taking the assets as an exchange operator would. Auditors tell the truth and can't be misled. That's because organizations that are regulated are incapable of lying and don't make mistakes.

First, some background. Here is a summary of how custodians make us more secure:

Previously, we might give Alice our crypto assets to hold. There were risks:

But "no worries", Alice has a custodian named Bob. Bob is dressed in a nice suit. He knows some politicians. And he drives a Porsche. "So you have nothing to worry about!". And look at all the benefits we get:
See - all problems are solved! All we have to worry about now is:
It's pretty simple. Before we had to trust Alice. Now we only have to trust Alice, Bob, and all the ways in which they communicate. Just think of how much more secure we are!

"On top of that", Bob assures us, "we're using a special wallet structure". Bob shows Alice a diagram. "We've broken the balance up and store it in lots of smaller wallets. That way", he assures her, "a thief can't take it all at once". And he points to a historic case where a large sum was taken "because it was stored in a single wallet... how stupid".
"Very early on, we used to have all the crypto in one wallet", he said, "and then one Christmas a hacker came and took it all. We call him the Grinch. Now we individually wrap each crypto and stick it under a binary search tree. The Grinch has never been back since."

"As well", Bob continues, "even if someone were to get in, we've got insurance. It covers all thefts and even coercion, collusion, and misplaced keys - only subject to the policy terms and conditions." And with that, he pulls out a phone-book sized contract and slams it on the desk with a thud. "Yep", he continues, "we're paying top dollar for one of the best policies in the country!"
"Can I read it?' Alice asks. "Sure," Bob says, "just as soon as our legal team is done with it. They're almost through the first chapter." He pauses, then continues. "And can you believe that sales guy Mike? He has the same year Porsche as me. I mean, what are the odds?"

"Do you use multi-sig?", Alice asks. "Absolutely!" Bob replies. "All our engineers are fully trained in multi-sig. Whenever we want to set up a new wallet, we generate 2 separate keys in an air-gapped process and store them in this proprietary system here. Look, it even requires the biometric signature from one of our team members to initiate any withdrawal." He demonstrates by pressing his thumb into the display. "We use a third-party cloud validation API to match the thumbprint and authorize each withdrawal. The keys are also backed up daily to an off-site third-party."
"Wow that's really impressive," Alice says, "but what if we need access for a withdrawal outside of office hours?" "Well that's no issue", Bob says, "just send us an email, call, or text message and we always have someone on staff to help out. Just another part of our strong commitment to all our customers!"

"What about Proof of Reserve?", Alice asks. "Of course", Bob replies, "though rather than publish any blockchain addresses or signed transaction, for privacy we just do a SHA256 refactoring of the inverse hash modulus for each UTXO nonce and combine the smart contract coefficient consensus in our hyperledger lightning node. But it's really simple to use." He pushes a button and a large green checkmark appears on a screen. "See - the algorithm ran through and reserves are proven."
"Wow", Alice says, "you really know your stuff! And that is easy to use! What about fiat balances?" "Yeah, we have an auditor too", Bob replies, "Been using him for a long time so we have quite a strong relationship going! We have special books we give him every year and he's very efficient! Checks the fiat, crypto, and everything all at once!"

"We used to have a nice offline multi-sig setup we've been using without issue for the past 5 years, but I think we'll move all our funds over to your facility," Alice says. "Awesome", Bob replies, "Thanks so much! This is perfect timing too - my Porsche got a dent on it this morning. We have the paperwork right over here." "Great!", Alice replies.
And with that, Alice gets out her pen and Bob gets the contract. "Don't worry", he says, "you can take your crypto-assets back anytime you like - just subject to our cancellation policy. Our annual management fees are also super low and we don't adjust them often".

How many holes have to exist for your funds to get stolen?
Just one.

Why are we taking a powerful offline multi-sig setup, widely used globally in hundreds of different/lacking regulatory environments with 0 breaches to date, and circumventing it by a demonstrably weak third party layer? And paying a great expense to do so?
If you go through the list of breaches in the past 2 years to highly credible organizations, you go through the list of major corporate frauds (only the ones we know about), you go through the list of all the times platforms have lost funds, you go through the list of times and ways that people have lost their crypto from identity theft, hot wallet exploits, extortion, etc... and then you go through this custodian with a fine-tooth comb and truly believe they have value to add far beyond what you could, sticking your funds in a wallet (or set of wallets) they control exclusively is the absolute worst possible way to take advantage of that security.

The best way to add security for crypto-assets is to make a stronger multi-sig. With one custodian, what you are doing is giving them your cryptocurrency and hoping they're honest, competent, and flawlessly secure. It's no different than storing it on a really secure exchange. Maybe the insurance will cover you. Didn't work for Bitpay in 2015. Didn't work for Yapizon in 2017. Insurance has never paid a claim in the entire history of cryptocurrency. But maybe you'll get lucky. Maybe your exact scenario will buck the trend and be what they're willing to cover. After the large deductible and hopefully without a long and expensive court battle.

And you want to advertise this increase in risk, the lapse of judgement, an accident waiting to happen, as though it's some kind of benefit to customers ("Free institutional-grade storage for your digital assets.")? And then some people are writing to the OSC that custodians should be mandatory for all funds on every exchange platform? That this somehow will make Canadians as a whole more secure or better protected compared with standard air-gapped multi-sig? On what planet?

Most of the problems in Canada stemmed from one thing - a lack of transparency. If Canadians had known what a joke Quadriga was - it wouldn't have grown to lose $400m from hard-working Canadians from coast to coast to coast. And Gerald Cotten would be in jail, not wherever he is now (at best, rotting peacefully). EZ-BTC and mister Dave Smilie would have been a tiny little scam to his friends, not a multi-million dollar fraud. Einstein would have got their act together or been shut down BEFORE losing millions and millions more in people's funds generously donated to criminals. MapleChange wouldn't have even been a thing. And maybe we'd know a little more about CoinTradeNewNote - like how much was lost in there. Almost all of the major losses with cryptocurrency exchanges involve deception with unbacked funds.
So it's great to see transparency reports from BitBuy and ShakePay where someone independently verified the backing. The only thing we don't have is:
It's not complicated to validate cryptocurrency assets. They need to exist, they need to be spendable, and they need to cover the total balances. There are plenty of credible people and firms across the country that have the capacity to reasonably perform this validation. Having more frequent checks by different, independent, parties who publish transparent reports is far more valuable than an annual check by a single "more credible/official" party who does the exact same basic checks and may or may not publish anything. Here's an example set of requirements that could be mandated:
There are ways to structure audits such that neither crypto assets nor customer information are ever put at risk, and both can still be properly validated and publicly verifiable. There are also ways to structure audits such that they are completely reasonable for small platforms and don't inhibit innovation in any way. By making the process as reasonable as possible, we can completely eliminate any reason/excuse that an honest platform would have for not being audited. That is arguable far more important than any incremental improvement we might get from mandating "the best of the best" accountants. Right now we have nothing mandated and tons of Canadians using offshore exchanges with no oversight whatsoever.

Transparency does not prove crypto assets are safe. CoinTradeNewNote, Flexcoin ($600k), and Canadian Bitcoins ($100k) are examples where crypto-assets were breached from platforms in Canada. All of them were online wallets and used no multi-sig as far as any records show. This is consistent with what we see globally - air-gapped multi-sig wallets have an impeccable record, while other schemes tend to suffer breach after breach. We don't actually know how much CoinTrader lost because there was no visibility. Rather than publishing details of what happened, the co-founder of CoinTrader silently moved on to found another platform - the "most trusted way to buy and sell crypto" - a site that has no information whatsoever (that I could find) on the storage practices and a FAQ advising that “[t]rading cryptocurrency is completely safe” and that having your own wallet is “entirely up to you! You can certainly keep cryptocurrency, or fiat, or both, on the app.” Doesn't sound like much was learned here, which is really sad to see.
It's not that complicated or unreasonable to set up a proper hardware wallet. Multi-sig can be learned in a single course. Something the equivalent complexity of a driver's license test could prevent all the cold storage exploits we've seen to date - even globally. Platform operators have a key advantage in detecting and preventing fraud - they know their customers far better than any custodian ever would. The best job that custodians can do is to find high integrity individuals and train them to form even better wallet signatories. Rather than mandating that all platforms expose themselves to arbitrary third party risks, regulations should center around ensuring that all signatories are background-checked, properly trained, and using proper procedures. We also need to make sure that signatories are empowered with rights and responsibilities to reject and report fraud. They need to know that they can safely challenge and delay a transaction - even if it turns out they made a mistake. We need to have an environment where mistakes are brought to the surface and dealt with. Not one where firms and people feel the need to hide what happened. In addition to a knowledge-based test, an auditor can privately interview each signatory to make sure they're not in coercive situations, and we should make sure they can freely and anonymously report any issues without threat of retaliation.
A proper multi-sig has each signature held by a separate person and is governed by policies and mutual decisions instead of a hierarchy. It includes at least one redundant signature. For best results, 3of4, 3of5, 3of6, 4of5, 4of6, 4of7, 5of6, or 5of7.

History has demonstrated over and over again the risk of hot wallets even to highly credible organizations. Nonetheless, many platforms have hot wallets for convenience. While such losses are generally compensated by platforms without issue (for example Poloniex, Bitstamp, Bitfinex, Gatecoin, Coincheck, Bithumb, Zaif, CoinBene, Binance, Bitrue, Bitpoint, Upbit, VinDAX, and now KuCoin), the public tends to focus more on cases that didn't end well. Regardless of what systems are employed, there is always some level of risk. For that reason, most members of the public would prefer to see third party insurance.
Rather than trying to convince third party profit-seekers to provide comprehensive insurance and then relying on an expensive and slow legal system to enforce against whatever legal loopholes they manage to find each and every time something goes wrong, insurance could be run through multiple exchange operators and regulators, with the shared interest of having a reputable industry, keeping costs down, and taking care of Canadians. For example, a 4 of 7 multi-sig insurance fund held between 5 independent exchange operators and 2 regulatory bodies. All Canadian exchanges could pay premiums at a set rate based on their needed coverage, with a higher price paid for hot wallet coverage (anything not an air-gapped multi-sig cold wallet). Such a model would be much cheaper to manage, offer better coverage, and be much more reliable to payout when needed. The kind of coverage you could have under this model is unheard of. You could even create something like the CDIC to protect Canadians who get their trading accounts hacked if they can sufficiently prove the loss is legitimate. In cases of fraud, gross negligence, or insolvency, the fund can be used to pay affected users directly (utilizing the last transparent balance report in the worst case), something which private insurance would never touch. While it's recommended to have official policies for coverage, a model where members vote would fully cover edge cases. (Could be similar to the Supreme Court where justices vote based on case law.)
Such a model could fully protect all Canadians across all platforms. You can have a fiat coverage governed by legal agreements, and crypto-asset coverage governed by both multi-sig and legal agreements. It could be practical, affordable, and inclusive.

Now, we are at a crossroads. We can happily give up our freedom, our innovation, and our money. We can pay hefty expenses to auditors, lawyers, and regulators year after year (and make no mistake - this cost will grow to many millions or even billions as the industry grows - and it will be borne by all Canadians on every platform because platforms are not going to eat up these costs at a loss). We can make it nearly impossible for any new platform to enter the marketplace, forcing Canadians to use the same stagnant platforms year after year. We can centralize and consolidate the entire industry into 2 or 3 big players and have everyone else fail (possibly to heavy losses of users of those platforms). And when a flawed security model doesn't work and gets breached, we can make it even more complicated with even more people in suits making big money doing the job that blockchain was supposed to do in the first place. We can build a system which is so intertwined and dependent on big government, traditional finance, and central bankers that it's future depends entirely on that of the fiat system, of fractional banking, and of government bail-outs. If we choose this path, as history has shown us over and over again, we can not go back, save for revolution. Our children and grandchildren will still be paying the consequences of what we decided today.
Or, we can find solutions that work. We can maintain an open and innovative environment while making the adjustments we need to make to fully protect Canadian investors and cryptocurrency users, giving easy and affordable access to cryptocurrency for all Canadians on the platform of their choice, and creating an environment in which entrepreneurs and problem solvers can bring those solutions forward easily. None of the above precludes innovation in any way, or adds any unreasonable cost - and these three policies would demonstrably eliminate or resolve all 109 historic cases as studied here - that's every single case researched so far going back to 2011. It includes every loss that was studied so far not just in Canada but globally as well.
Unfortunately, finding answers is the least challenging part. Far more challenging is to get platform operators and regulators to agree on anything. My last post got no response whatsoever, and while the OSC has told me they're happy for industry feedback, I believe my opinion alone is fairly meaningless. This takes the whole community working together to solve. So please let me know your thoughts. Please take the time to upvote and share this with people. Please - let's get this solved and not leave it up to other people to do.

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake
https://preview.redd.it/b80c05tnb9e51.jpg?width=2550&format=pjpg&auto=webp&s=850282c1a3962466ed44f73886dae1c8872d0f31
Submitted for consideration to The Great Reddit Scaling Bake-Off
Baked by the pastry chefs at Offchain Labs
Please send questions or comments to [[email protected] ](mailto:[email protected])
1. Overview
We're excited to submit Arbitrum Rollup for consideration to The Great Reddit Scaling Bake-Off. Arbitrum Rollup is the only Ethereum scaling solution that supports arbitrary smart contracts without compromising on Ethereum's security or adding points of centralization. For Reddit, this means that Arbitrum can not only scale the minting and transfer of Community Points, but it can foster a creative ecosystem built around Reddit Community Points enabling points to be used in a wide variety of third party applications. That's right -- you can have your cake and eat it too!
Arbitrum Rollup isn't just Ethereum-style. Its Layer 2 transactions are byte-for-byte identical to Ethereum, which means Ethereum users can continue to use their existing addresses and wallets, and Ethereum developers can continue to use their favorite toolchains and development environments out-of-the-box with Arbitrum. Coupling Arbitrum’s tooling-compatibility with its trustless asset interoperability, Reddit not only can scale but can onboard the entire Ethereum community at no cost by giving them the same experience they already know and love (well, certainly know).
To benchmark how Arbitrum can scale Reddit Community Points, we launched the Reddit contracts on an Arbitrum Rollup chain. Since Arbitrum provides full Solidity support, we didn't have to rewrite the Reddit contracts or try to mimic their functionality using an unfamiliar paradigm. Nope, none of that. We launched the Reddit contracts unmodified on Arbitrum Rollup complete with support for minting and distributing points. Like every Arbitrum Rollup chain, the chain included a bridge interface in which users can transfer Community Points or any other asset between the L1 and L2 chains. Arbitrum Rollup chains also support dynamic contract loading, which would allow third-party developers to launch custom ecosystem apps that integrate with Community Points on the very same chain that runs the Reddit contracts.
1.1 Why Ethereum
Perhaps the most exciting benefit of distributing Community Points using a blockchain is the ability to seamlessly port points to other applications and use them in a wide variety of contexts. Applications may include simple transfers such as a restaurant that allows Redditors to spend points on drinks. Or it may include complex smart contracts -- such as placing Community Points as a wager for a multiparty game or as collateral in a financial contract.
The common denominator between all of the fun uses of Reddit points is that it needs a thriving ecosystem of both users and developers, and the Ethereum blockchain is perhaps the only smart contract platform with significant adoption today. While many Layer 1 blockchains boast lower cost or higher throughput than the Ethereum blockchain, more often than not, these attributes mask the reality of little usage, weaker security, or both.
Perhaps another platform with significant usage will rise in the future. But today, Ethereum captures the mindshare of the blockchain community, and for Community Points to provide the most utility, the Ethereum blockchain is the natural choice.
1.2 Why Arbitrum
While Ethereum's ecosystem is unmatched, the reality is that fees are high and capacity is too low to support the scale of Reddit Community Points. Enter Arbitrum. Arbitrum Rollup provides all of the ecosystem benefits of Ethereum, but with orders of magnitude more capacity and at a fraction of the cost of native Ethereum smart contracts. And most of all, we don't change the experience from users. They continue to use the same wallets, addresses, languages, and tools.
Arbitrum Rollup is not the only solution that can scale payments, but it is the only developed solution that can scale both payments and arbitrary smart contracts trustlessly, which means that third party users can build highly scalable add-on apps that can be used without withdrawing money from the Rollup chain. If you believe that Reddit users will want to use their Community Points in smart contracts--and we believe they will--then it makes the most sense to choose a single scaling solution that can support the entire ecosystem, eliminating friction for users.
We view being able to run smart contracts in the same scaling solution as fundamentally critical since if there's significant demand in running smart contracts from Reddit's ecosystem, this would be a load on Ethereum and would itself require a scaling solution. Moreover, having different scaling solutions for the minting/distribution/spending of points and for third party apps would be burdensome for users as they'd have to constantly shuffle their Points back and forth.
2. Arbitrum at a glance
Arbitrum Rollup has a unique value proposition as it offers a combination of features that no other scaling solution achieves. Here we highlight its core attributes.
Decentralized. Arbitrum Rollup is as decentralized as Ethereum. Unlike some other Layer 2 scaling projects, Arbitrum Rollup doesn't have any centralized components or centralized operators who can censor users or delay transactions. Even in non-custodial systems, centralized components provide a risk as the operators are generally incentivized to increase their profit by extracting rent from users often in ways that severely degrade user experience. Even if centralized operators are altruistic, centralized components are subject to hacking, coercion, and potential liability.
Massive Scaling. Arbitrum achieves order of magnitude scaling over Ethereum's L1 smart contracts. Our software currently supports 453 transactions-per-second for basic transactions (at 1616 Ethereum gas per tx). We have a lot of room left to optimize (e.g. aggregating signatures), and over the next several months capacity will increase significantly. As described in detail below, Arbitrum can easily support and surpass Reddit's anticipated initial load, and its capacity will continue to improve as Reddit's capacity needs grow.
Low cost. The cost of running Arbitrum Rollup is quite low compared to L1 Ethereum and other scaling solutions such as those based on zero-knowledge proofs. Layer 2 fees are low, fixed, and predictable and should not be overly burdensome for Reddit to cover. Nobody needs to use special equipment or high-end machines. Arbitrum requires validators, which is a permissionless role that can be run on any reasonable on-line machine. Although anybody can act as a validator, in order to protect against a “tragedy of the commons” and make sure reputable validators are participating, we support a notion of “invited validators” that are compensated for their costs. In general, users pay (low) fees to cover the invited validators’ costs, but we imagine that Reddit may cover this cost for its users. See more on the costs and validator options below.
Ethereum Developer Experience. Not only does Arbitrum support EVM smart contracts, but the developer experience is identical to that of L1 Ethereum contracts and fully compatible with Ethereum tooling. Developers can port existing Solidity apps or write new ones using their favorite and familiar toolchains (e.g. Truffle, Buidler). There are no new languages or coding paradigms to learn.
Ethereum wallet compatibility. Just as in Ethereum, Arbitrum users need only hold keys, but do not have to store any coin history or additional data to protect or access their funds. Since Arbitrum transactions are semantically identical to Ethereum L1 transactions, existing Ethereum users can use their existing Ethereum keys with their existing wallet software such as Metamask.
Token interoperability. Users can easily transfer their ETH, ERC-20 and ERC-721 tokens between Ethereum and the Arbitrum Rollup chain. As we explain in detail below, it is possible to mint tokens in L2 that can subsequently be withdrawn and recognized by the L1 token contract.
Fast finality. Transactions complete with the same finality time as Ethereum L1 (and it's possible to get faster finality guarantees by trading away trust assumptions; see the Arbitrum Rollup whitepaper for details).
Non-custodial. Arbitrum Rollup is a non-custodial scaling solution, so users control their funds/points and neither Reddit nor anyone else can ever access or revoke points held by users.
Censorship Resistant. Since it's completely decentralized, and the Arbitrum protocol guarantees progress trustlessly, Arbitrum Rollup is just as censorship-proof as Ethereum.
Block explorer. The Arbitrum Rollup block explorer allows users to view and analyze transactions on the Rollup chain.
Limitations
Although this is a bake-off, we're not going to sugar coat anything. Arbitrum Rollup, like any Optimistic Rollup protocol, does have one limitation, and that's the delay on withdrawals.
As for the concrete length of the delay, we've done a good deal of internal modeling and have blogged about this as well. Our current modeling suggests a 3-hour delay is sufficient (but as discussed in the linked post there is a tradeoff space between the length of the challenge period and the size of the validators’ deposit).
Note that this doesn't mean that the chain is delayed for three hours. Arbitrum Rollup supports pipelining of execution, which means that validators can keep building new states even while previous ones are “in the pipeline” for confirmation. As the challenge delays expire for each update, a new state will be confirmed (read more about this here).
So activity and progress on the chain are not delayed by the challenge period. The only thing that's delayed is the consummation of withdrawals. Recall though that any single honest validator knows immediately (at the speed of L1 finality) which state updates are correct and can guarantee that they will eventually be confirmed, so once a valid withdrawal has been requested on-chain, every honest party knows that the withdrawal will definitely happen. There's a natural place here for a liquidity market in which a validator (or someone who trusts a validator) can provide withdrawal loans for a small interest fee. This is a no-risk business for them as they know which withdrawals will be confirmed (and can force their confirmation trustlessly no matter what anyone else does) but are just waiting for on-chain finality.
3. The recipe: How Arbitrum Rollup works
For a description of the technical components of Arbitrum Rollup and how they interact to create a highly scalable protocol with a developer experience that is identical to Ethereum, please refer to the following documents:
Arbitrum Rollup Whitepaper
Arbitrum academic paper (describes a previous version of Arbitrum)
4. Developer docs and APIs
For full details about how to set up and interact with an Arbitrum Rollup chain or validator, please refer to our developer docs, which can be found at https://developer.offchainlabs.com/.
Note that the Arbitrum version described on that site is older and will soon be replaced by the version we are entering in Reddit Bake-Off, which is still undergoing internal testing before public release.
5. Who are the validators?
As with any Layer 2 protocol, advancing the protocol correctly requires at least one validator (sometimes called block producers) that is honest and available. A natural question is: who are the validators?
Recall that the validator set for an Arbitrum chain is open and permissionless; anyone can start or stop validating at will. (A useful analogy is to full nodes on an L1 chain.) But we understand that even though anyone can participate, Reddit may want to guarantee that highly reputable nodes are validating their chain. Reddit may choose to validate the chain themselves and/or hire third-party validators.To this end, we have begun building a marketplace for validator-for-hire services so that dapp developers can outsource validation services to reputable nodes with high up-time. We've announced a partnership in which Chainlink nodes will provide Arbitrum validation services, and we expect to announce more partnerships shortly with other blockchain infrastructure providers.
Although there is no requirement that validators are paid, Arbitrum’s economic model tracks validators’ costs (e.g. amount of computation and storage) and can charge small fees on user transactions, using a gas-type system, to cover those costs. Alternatively, a single party such as Reddit can agree to cover the costs of invited validators.
6. Reddit Contract Support
Since Arbitrum contracts and transactions are byte-for-byte compatible with Ethereum, supporting the Reddit contracts is as simple as launching them on an Arbitrum chain.
Minting. Arbitrum Rollup supports hybrid L1/L2 tokens which can be minted in L2 and then withdrawn onto the L1. An L1 contract at address A can make a special call to the EthBridge which deploys a "buddy contract" to the same address A on an Arbitrum chain. Since it's deployed at the same address, users can know that the L2 contract is the authorized "buddy" of the L1 contract on the Arbitrum chain.
For minting, the L1 contract is a standard ERC-20 contract which mints and burns tokens when requested by the L2 contract. It is paired with an ERC-20 contract in L2 which mints tokens based on whatever programmer provided minting facility is desired and burns tokens when they are withdrawn from the rollup chain. Given this base infrastructure, Arbitrum can support any smart contract based method for minting tokens in L2, and indeed we directly support Reddit's signature/claim based minting in L2.
Batch minting. What's better than a mint cookie? A whole batch! In addition to supporting Reddit’s current minting/claiming scheme, we built a second minting design, which we believe outperforms the signature/claim system in many scenarios.
In the current system, Reddit periodically issues signed statements to users, who then take those statements to the blockchain to claim their tokens. An alternative approach would have Reddit directly submit the list of users/amounts to the blockchain and distribute the tokens to the users without the signature/claim process.
To optimize the cost efficiency of this approach, we designed an application-specific compression scheme to minimize the size of the batch distribution list. We analyzed the data from Reddit's previous distributions and found that the data is highly compressible since token amounts are small and repeated, and addresses appear multiple times. Our function groups transactions by size, and replaces previously-seen addresses with a shorter index value. We wrote client code to compress the data, wrote a Solidity decompressing function, and integrated that function into Reddit’s contract running on Arbitrum.
When we ran the compression function on the previous Reddit distribution data, we found that we could compress batched minting data down to to 11.8 bytes per minting event (averaged over a 6-month trace of Reddit’s historical token grants)compared with roughly 174 bytes of on-chain data needed for the signature claim approach to minting (roughly 43 for an RLP-encoded null transaction + 65 for Reddit's signature + 65 for the user's signature + roughly 8 for the number of Points) .
The relative benefit of the two approaches with respect to on-chain call data cost depends on the percentage of users that will actually claim their tokens on chain. With the above figures, batch minting will be cheaper if roughly 5% of users redeem their claims. We stress that our compression scheme is not Arbitrum-specific and would be beneficial in any general-purpose smart contract platform.
8. Benchmarks and costs
In this section, we give the full costs of operating the Reddit contracts on an Arbitrum Rollup chain including the L1 gas costs for the Rollup chain, the costs of computation and storage for the L2 validators as well as the capital lockup requirements for staking.
Arbitrum Rollup is still on testnet, so we did not run mainnet benchmarks. Instead, we measured the L1 gas cost and L2 workload for Reddit operations on Arbitrum and calculated the total cost assuming current Ethereum gas prices. As noted below in detail, our measurements do not assume that Arbitrum is consuming the entire capacity of Ethereum. We will present the details of our model now, but for full transparency you can also play around with it yourself and adjust the parameters, by copying the spreadsheet found here.
Our cost model is based on measurements of Reddit’s contracts, running unmodified (except for the addition of a batch minting function) on Arbitrum Rollup on top of Ethereum.
On the distribution of transactions and frequency of assertions. Reddit's instructions specify the following minimum parameters that submissions should support:
Over a 5 day period, your scaling PoC should be able to handle:
  • 100,000 point claims (minting & distributing points)
  • 25,000 subscriptions
  • 75,000 one-off points burning
  • 100,000 transfers
We provide the full costs of operating an Arbitrum Rollup chain with this usage under the assumption that tokens are minted or granted to users in batches, but other transactions are uniformly distributed over the 5 day period. Unlike some other submissions, we do not make unrealistic assumptions that all operations can be submitted in enormous batches. We assume that batch minting is done in batches that use only a few percent on an L1 block’s gas, and that other operations come in evenly over time and are submitted in batches, with one batch every five minutes to keep latency reasonable. (Users are probably already waiting for L1 finality, which takes at least that long to achieve.)
We note that assuming that there are only 300,000 transactions that arrive uniformly over the 5 day period will make our benchmark numbers lower, but we believe that this will reflect the true cost of running the system. To see why, say that batches are submitted every five minutes (20 L1 blocks) and there's a fixed overhead of c bytes of calldata per batch, the cost of which will get amortized over all transactions executed in that batch. Assume that each individual transaction adds a marginal cost of t. Lastly assume the capacity of the scaling system is high enough that it can support all of Reddit's 300,000 transactions within a single 20-block batch (i.e. that there is more than c + 300,000*t byes of calldata available in 20 blocks).
Consider what happens if c, the per-batch overhead, is large (which it is in some systems, but not in Arbitrum). In the scenario that transactions actually arrive at the system's capacity and each batch is full, then c gets amortized over 300,000 transactions. But if we assume that the system is not running at capacity--and only receives 300,000 transactions arriving uniformly over 5 days-- then each 20-block assertion will contain about 200 transactions, and thus each transaction will pay a nontrivial cost due to c.
We are aware that other proposals presented scaling numbers assuming that 300,000 transactions arrived at maximum capacity and was executed in a single mega-transaction, but according to our estimates, for at least one such report, this led to a reported gas price that was 2-3 orders of magnitude lower than it would have been assuming uniform arrival. We make more realistic batching assumptions, and we believe Arbitrum compares well when batch sizes are realistic.
Our model. Our cost model includes several sources of cost:
  • L1 gas costs: This is the cost of posting transactions as calldata on the L1 chain, as well as the overhead associated with each batch of transactions, and the L1 cost of settling transactions in the Arbitrum protocol.
  • Validator’s staking costs: In normal operation, one validator will need to be staked. The stake is assumed to be 0.2% of the total value of the chain (which is assumed to be $1 per user who is eligible to claim points). The cost of staking is the interest that could be earned on the money if it were not staked.
  • Validator computation and storage: Every validator must do computation to track the chain’s processing of transactions, and must maintain storage to keep track of the contracts’ EVM storage. The cost of computation and storage are estimated based on measurements, with the dollar cost of resources based on Amazon Web Services pricing.
It’s clear from our modeling that the predominant cost is for L1 calldata. This will probably be true for any plausible rollup-based system.
Our model also shows that Arbitrum can scale to workloads much larger than Reddit’s nominal workload, without exhausting L1 or L2 resources. The scaling bottleneck will ultimately be calldata on the L1 chain. We believe that cost could be reduced substantially if necessary by clever encoding of data. (In our design any compression / decompression of L2 transaction calldata would be done by client software and L2 programs, never by an L1 contract.)
9. Status of Arbitrum Rollup
Arbitrum Rollup is live on Ethereum testnet. All of the code written to date including everything included in the Reddit demo is open source and permissively licensed under the Apache V2 license. The first testnet version of Arbitrum Rollup was released on testnet in February. Our current internal version, which we used to benchmark the Reddit contracts, will be released soon and will be a major upgrade.
Both the Arbitrum design as well as the implementation are heavily audited by independent third parties. The Arbitrum academic paper was published at USENIX Security, a top-tier peer-reviewed academic venue. For the Arbitrum software, we have engaged Trail of Bits for a security audit, which is currently ongoing, and we are committed to have a clean report before launching on Ethereum mainnet.
10. Reddit Universe Arbitrum Rollup Chain
The benchmarks described in this document were all measured using the latest internal build of our software. When we release the new software upgrade publicly we will launch a Reddit Universe Arbitrum Rollup chain as a public demo, which will contain the Reddit contracts as well as a Uniswap instance and a Connext Hub, demonstrating how Community Points can be integrated into third party apps. We will also allow members of the public to dynamically launch ecosystem contracts. We at Offchain Labs will cover the validating costs for the Reddit Universe public demo.
If the folks at Reddit would like to evaluate our software prior to our public demo, please email us at [email protected] and we'd be more than happy to provide early access.
11. Even more scaling: Arbitrum Sidechains
Rollups are an excellent approach to scaling, and we are excited about Arbitrum Rollup which far surpasses Reddit's scaling needs. But looking forward to Reddit's eventual goal of supporting hundreds of millions of users, there will likely come a time when Reddit needs more scaling than any Rollup protocol can provide.
While Rollups greatly reduce costs, they don't break the linear barrier. That is, all transactions have an on-chain footprint (because all calldata must be posted on-chain), albeit a far smaller one than on native Ethereum, and the L1 limitations end up being the bottleneck for capacity and cost. Since Ethereum has limited capacity, this linear use of on-chain resources means that costs will eventually increase superlinearly with traffic.
The good news is that we at Offchain Labs have a solution in our roadmap that can satisfy this extreme-scaling setting as well: Arbitrum AnyTrust Sidechains. Arbitrum Sidechains are similar to Arbitrum Rollup, but deviate in that they name a permissioned set of validators. When a chain’s validators agree off-chain, they can greatly reduce the on-chain footprint of the protocol and require almost no data to be put on-chain. When validators can't reach unanimous agreement off-chain, the protocol reverts to Arbitrum Rollup. Technically, Arbitrum Sidechains can be viewed as a hybrid between state channels and Rollup, switching back and forth as necessary, and combining the performance and cost that state channels can achieve in the optimistic case, with the robustness of Rollup in other cases. The core technical challenge is how to switch seamlessly between modes and how to guarantee that security is maintained throughout.
Arbitrum Sidechains break through this linear barrier, while still maintaining a high level of security and decentralization. Arbitrum Sidechains provide the AnyTrust guarantee, which says that as long as any one validator is honest and available (even if you don't know which one will be), the L2 chain is guaranteed to execute correctly according to its code and guaranteed to make progress. Unlike in a state channel, offchain progress does not require unanimous consent, and liveness is preserved as long as there is a single honest validator.
Note that the trust model for Arbitrum Sidechains is much stronger than for typical BFT-style chains which introduce a consensus "voting" protocols among a small permissioned group of validators. BFT-based protocols require a supermajority (more than 2/3) of validators to agree. In Arbitrum Sidechains, by contrast, all you need is a single honest validator to achieve guaranteed correctness and progress. Notice that in Arbitrum adding validators strictly increases security since the AnyTrust guarantee provides correctness as long as any one validator is honest and available. By contrast, in BFT-style protocols, adding nodes can be dangerous as a coalition of dishonest nodes can break the protocol.
Like Arbitrum Rollup, the developer and user experiences for Arbitrum Sidechains will be identical to that of Ethereum. Reddit would be able to choose a large and diverse set of validators, and all that they would need to guarantee to break through the scaling barrier is that a single one of them will remain honest.
We hope to have Arbitrum Sidechains in production in early 2021, and thus when Reddit reaches the scale that surpasses the capacity of Rollups, Arbitrum Sidechains will be waiting and ready to help.
While the idea to switch between channels and Rollup to get the best of both worlds is conceptually simple, getting the details right and making sure that the switch does not introduce any attack vectors is highly non-trivial and has been the subject of years of our research (indeed, we were working on this design for years before the term Rollup was even coined).
12. How Arbitrum compares
We include a comparison to several other categories as well as specific projects when appropriate. and explain why we believe that Arbitrum is best suited for Reddit's purposes. We focus our attention on other Ethereum projects.
Payment only Rollups. Compared to Arbitrum Rollup, ZK-Rollups and other Rollups that only support token transfers have several disadvantages:
  • As outlined throughout the proposal, we believe that the entire draw of Ethereum is in its rich smart contracts support which is simply not achievable with today's zero-knowledge proof technology. Indeed, scaling with a ZK-Rollup will add friction to the deployment of smart contracts that interact with Community Points as users will have to withdraw their coins from the ZK-Rollup and transfer them to a smart contract system (like Arbitrum). The community will be best served if Reddit builds on a platform that has built-in, frictionless smart-contract support.
  • All other Rollup protocols of which we are aware employ a centralized operator. While it's true that users retain custody of their coins, the centralized operator can often profit from censoring, reordering, or delaying transactions. A common misconception is that since they're non-custodial protocols, a centralized sequencer does not pose a risk but this is incorrect as the sequencer can wreak havoc or shake down users for side payments without directly stealing funds.
  • Sidechain type protocols can eliminate some of these issues, but they are not trustless. Instead, they require trust in some quorum of a committee, often requiring two-third of the committee to be honest, compared to rollup protocols like Arbitrum that require only a single honest party. In addition, not all sidechain type protocols have committees that are diverse, or even non-centralized, in practice.
  • Plasma-style protocols have a centralized operator and do not support general smart contracts.
13. Concluding Remarks
While it's ultimately up to the judges’ palate, we believe that Arbitrum Rollup is the bakeoff choice that Reddit kneads. We far surpass Reddit's specified workload requirement at present, have much room to optimize Arbitrum Rollup in the near term, and have a clear path to get Reddit to hundreds of millions of users. Furthermore, we are the only project that gives developers and users the identical interface as the Ethereum blockchain and is fully interoperable and tooling-compatible, and we do this all without any new trust assumptions or centralized components.
But no matter how the cookie crumbles, we're glad to have participated in this bake-off and we thank you for your consideration.

The computational power of the Ethereum network (hashrate) has exceeded its historical maximum, having passed the 250 TH/s mark.
The growth of the hashrate occurs in parallel with the stable growth of network activity - since the beginning of 2020, the volume of transactions in the Ethereum blockchain has increased by more than 10-fold. And in Bitcoin, this figure has increased by 44% over the same period. This is due to the popularity of decentralized finance (DeFi). At the same time, the ETH price is still 76% lower than its January 2018 record highs.
So what?
ETH is among the stars. Even Bitcoin, being on everyones' lips and capturing the newspapers' titles, is getting a bit overshadowed by the fame of Ethereum.

Swipe Launches Network Staking and DeFi on Binance Smart Chain with Swipe Governance

Swipe Launches Network Staking and DeFi on Binance Smart Chain with Swipe Governance

https://preview.redd.it/ozt2j8wm9de51.jpg?width=1280&format=pjpg&auto=webp&s=77ffe561b0566f967acbac296508c6a96a9ce6e7
London, United Kingdom — Swipe is proud to announce that it has launched its test network for Swipe Network Staking and will launch a Decentralized Finance Lending/Earn application on Binance Smart Chain. Swipe, which was recently acquired by Binance, has garnered enormous growth over the past month in all avenues of its business and plans to launch a new product, feature, event, listing, or partnership every week until the end of the year.
Summary:
  • Testnet Staking Launched with testnet SXP on Ropsten
  • 12% APY for SXP Staking
  • DeFi coming to Binance Chain with BTC, ETH, BNB, SXP, BUSD, and TUSD collateral for borrowing/supplying
  • Swipe Governance Token airdrop to SXP Holders
  • Liquidity Mining on Binance Chain
  • New announcements weekly

Swipe Network

The Swipe Network (swipe.org) is the payment protocol that enables real-time crypto-to-fiat conversions for all of Swipe’s products and services (Wallet, Card, & Issuing). With the launch of the Swipe Network testnet, users can use the Swipe Faucet to grab testnet-SXP to use on the decentralized finance application.
Users will be able to bond SXP to the Swipe Network smart contract as collateral to ensure the guarantee of conversions for these exchanges. Since Swipe facilitates real-time conversions on-demand, there is a reserve system in place to lock SXP and guarantee that the merchant and payment networks receive the exact fiat amount that it processes. Most of these processes occur off-chain and are guaranteed by Swipe at the moment, but now can be bonded by the community and on-chain.
Users will receive 12% APY on their staked SXP within the Swipe Network. Swipe plans to enable staked SXP to earn the processing fees it charges in the future as well on top of the collateral rewards from staking. The main network for swipe.org will be launched in two weeks. Users can access the testnet from: https://testnet.swipe.org with a public faucet being released in the next few days. To promote the usage of Swipe Network, Swipe will be partnering with exchanges that will offer staking and enhanced initial rewards and will be announced soon.

Swipe Finance (SwipeFi) & SGV — Lending/Earning DeFi App built on Binance Smart Chain controlled by the community by the Swipe Governance Token (SGV) and Liquidity Mining.

Swipe is proud to announce its plans to launch a DeFi App on Binance Chain called SwipeFi which will enable Binance Chain tokens to be used to earn interest on their supply of collateral to the protocol and borrow against their collateral directly on the Binance blockchain. Swipe has been working with the core developers of Binance Smart Chain through the acquisition and partnerships between Swipe and Binance, to launch SwipeFi.
Users have witnessed historical highs in transaction fees, gas costs, and delays using the Ethereum blockchain for Decentralized Finance (DeFi). Bringing a complete lending/earn protocol using the battle-tested open-source protocols, such as Compound, to Binance chain gives users an immense value proposition.
Bitcoin, Ethereum, and other assets are already wrapped and issued on Binance Chain and are verifiable on their native blockchains for cross-compatibility, which will give exposure to use these assets for supplying and borrowing from SwipeFi. There are stablecoins such as BUSD, TUSD, and others that are also guaranteed on their native chains, which are wrapped and issued on Binance Chain already. Therefore, the base layer of the collateral needed to start a project of this magnitude already exists. Binance.com offers simple on and off-ramps for converting the Binance chain version to the native version (example: BTCB to BTC and vice versa) as well as SwipeFi plans to open up decentralized bridges for this wrapping.
Transactions on Binance Chain are considered one block finality, take less than ~5 seconds to complete, and cost a fraction of the price that it would cost on Ethereum. This will make DeFi transactions seamless and efficient.
SwipeFi will initially support BTC, BNB, ETH, BUSD, TUSD, and SXP to supply or borrow. The protocol will be governed by a new Binance Chain BEP2 token: Swipe Governance Token (SGV). SGV will be used on the protocol to vote on proposals and governance decisions while earned through liquidity mining so that the supplier and borrowers of the protocol can be incentivized to participate in governance as well. There will be a total supply of 10,000,000 SGV ever in existence.
On August 17, 2020, at 00:00 UTC, there will be a snapshot of SXP balances. There will be a distribution of 1 SGV per 100 SXP.
This will give an initial supply of approximately 2,999,700 SGV with the remaining SGV to be mined via Liquidity Mining by supplying and borrowing on the protocol over a 5 year period.
There will be no SGV sold or allocated to the team aside from what they already hold in SXP. This will enable users to mine over 70% of the total SGV supply over a five year period. Swipe will release the SwipeFi white paper and governance details by August 10, 2020, with plans to launch a testnet in September.

Free bitcoin usd ticker??

I’m looking for an intraday Bitcoin usd ticker data feed API that I don’t need to pay for. Not historical, just ticker data. Happy to have typical ohlcv or just prices and volumes.
Happy to deal with rest or web socket or Mqtt or whatever just something that is straightforward and works.
If this isn’t the right place can someone point me in the right direction? If you think think the answer is too obvious, don’t underestimate my level of idiocy and just ELI5; I’m alright with python and internet protocol fundamentals just getting really frustrated.
Thanks in advance

Cryptarbitrage’s Deribit Spreadsheets Calculation Tools

Perpetuals, Futures, and Options can present quite a steep learning curve, fear not though as we have an incredible collection of Google Sheets and Excel Spreadsheets to help both the basic as well as most advanced users! We can also strongly recommend reading our Educational and Market Research articles as many traders find them to be invaluable resources.

One of our talented Community Managers, Cryptarbitrage, has created and maintains to the best of his ability a series of tools to both help Deribit users learn more about BTC & ETH Perpetuals, Futures, and Options as well support more advanced traders increasing technical needs.
A short introduction by Cryptarbitrage:
"Although I was aware of options beforehand I only started properly researching them in early 2018 after I discovered the Bitcoin options on Deribit. I do not need much encouragement to build a spreadsheet for something so quickly set about created an Excel sheet that would show me the profit and loss of any options position I entered.
This was a great way to learn all the profit and loss formulas for each type of option as well as how different option combinations interacted with each other. As soon as this sheet was complete I was building positions I still didn’t even know the proper names for so was very much learning by doing. It was immediately obvious to me though that options were the type of instruments I wanted to trade.
After a few months and once I’d done some more reading and was more confident I actually knew what I was talking about I began creating shareable versions in google sheets and sharing them with the Deribit community."

Bitcoin Madness: How to Simulate Bitcoin Prices in Google Sheets

Original Medium post can be found here: https://medium.com/@spreadstreet/bitcoin-madness-how-to-simulate-bitcoin-prices-in-google-sheets-c61cb42f26ed
You know the scenario...
Bitcoin had another huge increase, but you missed the opportunity. You wanted to get in, but your gut instinct told you no. And rightfully so...no one knows where the price is going to go. What if you invested, and it had another 20% loss? These sort of price movements are common in the volatile world of cryptocurrencies.
Seriously...how far can this Bitcoin price really go?

BITCOIN IS A VOLATILE BEAST

Risk analysis must be a part of every decision you make.
You are constantly faced with uncertainty, ambiguity, and variability. Variability, in the case of Bitcoin, unlike anything we have ever seen before. And even though we have unprecedented access to information, we can’t accurately predict the future.
Luckily, we have methods that enable you to see all the possible outcomes of your decisions, and assess the impact of risk.

WHERE TO START?

Running simulations can prepare us for the worst.
Monte Carlo simulation (also known as the Monte Carlo Method) allows for better decision making under uncertainty.
One of the most common ways to estimate risk is the use of a Monte Carlo simulation (MCS). From Investopedia:
For example, to calculate the value at risk (VaR) of a portfolio, we can run a Monte Carlo simulation that attempts to predict the worst likely loss for a portfolio given a confidence interval over a specified time horizon - we always need to specify two conditions for VaR: confidence and horizon. (For related reading, see The Uses And Limits Of Volatility and Introduction To Value At Risk (VAR) - Part 1 and Part 2.)
A MCS can be run with many different models. Our own process will be:
  1. Specify a model (for here, we will use geometric Brownian motion)
  2. Get historical daily bitcoin prices
  3. Calculate daily returns
  4. Name the daily return range
  5. Summary statistics
  6. Simulate a year
  7. Simulate a year many times
  8. Multi-year summary statistics
  9. Quick analysis of results

STEP 1. WTF IS GEOMETRIC BROWNIAN MOTION?

The geometric Brownian motion (GBM) is a statistical method that is used heavily in the forecasting of stock prices. The reason the process is so attractive for this is because of the following:
The GBM is technically a Markov process, which is a fancy way of saying "A random process whose future probabilities are determined by its most recent values." Said another way, past price information is already incorporated and the next price movement is "conditionally independent" of past price movements.
Math geeks have a habit of making things infinitely more complicated than they have to be. I will do my best to make this as simple as possible.
The formula for GBM is as follows:
gBm formula
Where:
This formula can be broken down into two very important terms: "drift" and "shock".
For each time period, our model assumes the price will "drift" up by the expected return. But the drift will be shocked (added or subtracted) by a random shock. The random shock will be the standard deviation "s" multiplied by a random number "e". This is simply a way of scaling the standard deviation.

STEP 1A. THE THUNDER GOD ELI5

The ELI5 version: The thunder god Zeus is a great god. A just god.
But Zeus is subject to wild mood swings.
Every day Zeus can shoot his magic lightning into the price of Bitcoin, and cause it to go up or down.
Some days he is in such a good mood, that he shocks the price up by a random amount. On other days, he is in such a poor mood that he shocks the price down for opposing him.
Zeus Striking Down the Price
And thus, we have the essence of GBM: a series of steps with an expected upward drift, where each step is hit with a plus/minus shock (which is a function of the stock's standard deviation).

STEP 2. HISTORICAL DAILY BITCOIN PRICES

Copy the raw data scores from coinmarketcap. Paste the data into your own spreadsheet.
For this exercise, your columns will be: Time, Open, Close, High, Low, Volume.
Columns Setup OHLCV
Want to automatically pull in Bitcoin prices? Use the Spreadstreet Google Sheets Add-in.

STEP 3. CALCULATE DAILY RETURNS

Calculate daily returns from the "Close" price. in H2 put the formula:
=LN(C2/B2) 
Drag it all the way down to the end of the prices to fill the entire Returns column
Calculate Daily Returns

STEP 4. NAME THE DAILY RETURNS RANGE

Create a named range from the returns column, called returns, to make our life easier. Highlight all the data in column H, i.e. cells H1:H1000, then click on the menu Data > Named ranges… and call the range returns:
Name the range returns

STEP 5. SUMMARY STATISTICS

Set up a small summary table with the close, daily volatility, annual volatility, daily drift, annual drift, and mean drift of our population. The formulas are:
In K1, enter:
=C2 
and name it close.
In K2, enter:
=STDEV(returns) 
and name it dailyVolatility
In K3, enter:
=dailyVolatility*SQRT(365) 
and name it annualVolatility
In K4, enter:
=AVERAGE(returns) 
and name it dailyDrift
In K5, enter:
=dailyDrift*365 
and name it annualDrift
In K6, enter:
=dailyDrift-0.5*dailyVolatility^2 
and name it meanDrift
Create Summary Statistics Table

STEP 6. SIMULATE A YEAR

Setup the yearly simulation table with Time, Normdist, Log Return, and Simulated Price

Time

In J12 put 0, and in J13 put:
=J12+1 
Drag it all the way down to your preferred forecast timeframe. Here I simulated a year (365 days), so I copied down to J377
Time

Normdist

Let’s set up the normal distribution curve values.
Google Sheets has a formula NORMDIST which calculates the value of the normal distribution function for a given value, mean and standard deviation. Since we ascribe to the random walk theory, we want to use a mean of 0, and a standard deviation of 1.
In K13, put the formula:
=NORMINV(RAND(),0,1) 
Drag it all the way down to K377 to fill the whole Normdist column:
Normdist

Log Return

To get the percentage of daily stock movement, we will calculate log return.
In L13, put the formula:
=meanDrift+dailyVolatility*K13 
Copy the formula all the way down to L377:
Log Return

Simulated Price

Now to the real meat. Let's calculate the simulated Bitcoin price.
In M12 put the Close price, and in M13, put:
=M12*EXP(L13) 
Copy the formula all the way down to M377:
Simulated Price

Forecasted Bitcoin price for one year

Let's see what the pricing data looks like.
Select from M12 to M377, then Insert - Chart and select line chart:
Simulated Price for One Year
We have now successfully completed one simulation. And depending on your results, they could look normal...or downright crazy.

STEP 7. SIMULATE A YEAR MANY TIMES

We completed one simulation, but we want to run many different trials.
Create a scenario tab, setup a table to simulate 1,000 different one-year trials. In A3 to A1003, put the numbers 1 through 1000.
In B3, put the formula:
=Close*EXP((annualDrift-0.5*annualVolatility^2)+annualVolatility*norminv(rand(),0,1)) 
Copy the formula down all the way. Name this range "scores":
Simulate Bitcoin Prices for Many Years

STEP 8. MULTI-YEAR SUMMARY STATISTICS

Set up a small summary table with the mean, median, standard deviation, min, max, and range of our new population. The formulas are:
=AVERAGE(scores) =STDEVP(scores) =MIN(scores) =MAX(scores) =E6-E5 
Multiyear Summary Statistics

STEP 9. QUICK ANALYSIS OF RESULTS

My results will look different than yours (due to the random nature of NORMDIST and the time you pulled the Bitcoin prices). But let's take a look at the results:
Mean $27,147 Median $16,097 St. Dev $37,243 Min $556 Max $479,586 Range $479,029 3sd $1,486 2sd $3,005 1sd $5,850 Cur $16,098 1sd $43,896 2sd $81,998 3sd $190,129 
How to read: We can be 95% certain that the price of Bitcoin will fall between $3,005, and $81,998 in one year.
Wait really? Should I buy? No, this is not telling you to buy. This should be one tool of many to help you in your buying and risk decisions.
Lognormal Distribution of Bitcoin Prices

CONCLUSION

You now know how to complete a geometric Brownian motion analysis of Bitcoin prices. Congratulations!
Good statistical analysis methods can be scary, but they don't have to be. Here we covered off on a great method for estimating future Bitcoin prices, which can also be applied to other cryptocurrencies.
With this new tool in place, you can be confident in your risk analysis methods by seeing all the possible outcomes of your decisions, and assess the impact of risk.
Deliberate. Analytical. Intelligent.

How do you file taxes if you are a daily crypto trader?

So I bought a couple of coins back in 2017 say 2.5LTC, now my current holding + mining is about 4.5LTC. I buy and sell in Coinbase(PRO) and I accumulated about 2000 transactions last year. Do I need to put those 2000 transactions when filing tax or can I just indicate the initial and current value of my holdings? And one thing, the current value of my LTC is lower than the current value when I bought, in short I did not earn in terms of USD value. TIA

Survivors of market disasters: In this disaster, some people actually made money

There is no need to repeat the tragic market. Various historical figures are present, and they all reveal a signal: this disaster is like an earthquake with no warning signs. The victims are everywhere, and the survival is a fluke.
But in this disaster, there are still people who make money.
If you still have the impression, on August 23 of last year, there was a problem with Amazon AWS 'server in Japan, which caused the products using the region's services to be affected to varying degrees, including the cryptocurrency trading platform. After discovering a problem with Binance using AWS, the user's deposit and withdrawal were suspended, but the trading platform using the Binance Quotation API failed to take timely measures, resulting in loopholes in market makers' strategies.
That day, while Bitcoin was still steadily maintained at 10,000 USD, some users bought Bitcoin at a unit price of 0.32 USD, and when there was almost no fluctuation in the market, they used the mistake of the server to add western food for the night. A bottle of champagne.
In this disaster after 5 months, some people still use the environment to find a way to survive.
Ethereum 0 dollar purchase?
A $ 0 purchase of Ethereum happened on March 13. The market plummeted, many mortgagors' positions were exploded, and ETH fell from $ 180 to less than $ 100 without resistance. The decentralized Defi market that depends on the value of ETH is naturally not immune, such as the MakerDAO platform. MakerDAO's borrowing logic is that users over-collateralize ETH to lend USD stablecoin DAI, but when the value of ETH fell rapidly, a large number of loans fell below the threshold and the system had to be liquidated. In other words, the user's loan was not repaid. Mortgage of ETH is also not available.
So MakerDAO has a bad debt, the amount exceeds USD 4 million. In order to repay this bad debt, MakerDAO chooses to auction the collateral, that is, ETH, BAT, etc., and uses the stable currency DAI to bid. They need to use the auction proceeds to obtain repay loan.
Under normal circumstances, such auctions are not too accidental. The feeding system reports the current price of ETH, and the bidders will probably trade at a price slightly lower than the market price.
However, the background of this auction is the market's plunge. The transaction caused investors to intensive operations, which blocked the Ethereum network. It takes far more than usual gas fees to allow the miners to confirm the transfer as soon as possible.
According to the browser, on the morning of the 13th, if only 44 gwei is used, the transfer confirmation time on the Ethereum network will take 72958 seconds, which is 20 hours.
The MakerDAO debt auction on the Ethereum network has also been affected. The blockage of the network has prevented bidders with low gas costs from bidding in time, which caused participants to bid 0 DAI / ETH to drop the hammer.
It can also be seen from the transaction records that the auction of 0 DAI was indeed successful. These lucky bidders only paid a transfer fee of US $ 1 and transferred 0 amount to obtain an ETH worth US $ 122 at the time.
These people are undoubtedly fortunate. The external environment helped them to become the only game participants. The exchange of $ 1 for $ 120 and a profit of 11900% was much higher than the odds of players who risked bottom-swinging in fluctuations.
However, from another perspective, MakerDAO's auction is to use the DAI obtained from the auction to pay off debts. However, due to network congestion, this situation has caused several free gifts, and MakerDAO's debt repayment is even worse.
Pick up goods by luck
If it is said that MakerDAO launches the auction, it is a helpless action of the team under extreme conditions. Bidders still need a bit of technical barriers to participate, but there is nothing to worry about, and there is almost no difficulty and cost.
On the evening of March 12, investors discovered that the LINK / USDT trading pair of the Binance trading platform experienced a short-term flash collapse and once fell to the bottom 0.0001 USD. What's going on?
Twitter netizens then asked Zhao Changpeng about the matter, and the latter's response was a shock. It turned out that someone had already launched the LINK trading pair as early as Binance, that is, on January 16 last year, a low was hung within 8 seconds after the real-time trading was opened. Price list, but it has not been closed because no fool will sell it at this price.
Unexpectedly, more than a year later, this pending order was sold "strangely". "At that time we had no price range restrictions. We will not cancel user orders." Zhao Changpeng said that the platform will not deny this order because the operation is completely reasonable.
It will not be rolled back for various reasons. In other words, even if LINK has experienced a large decline recently, at the current price of 2.3 US dollars, the profit of this transaction will exceed 2 million US dollars. US dollars, then he instantly won nearly 5 million US dollars.
The cost of 100 dollars, the income of 2.4 million dollars, a real profit.
In fact, similar examples of this kind of luck are not rare in the crypto industry. Except for Binance and the previous examples, BitMex and OKEx have also experienced similar situations, and more than once.
For example, on December 6, 2017, Binance's XRP / BTC trading pair experienced a breakdown of the list. In a very short period of time, the XRP price was oversold to 0.0000002 BTC, which is basically negligible. On January 29, 2018, the price of the ADA contract on BitMEX also fell to 0.00000005 US dollars, which was also nearly 0; another trading platform, OKEx, also saw a large amount of 0.002 USD on January 14, 2018. Case, according to the official statement at that time, "a certain trader" quickly sold a large amount of ETH through market orders within 12 minutes. Interestingly, at the time, some people analyzed that "a certain trader" was actually an official market-making robot, and "a large amount" of 100 million Ethereum was eventually sold for 20 dollars.
However, for ordinary people, if you want to encounter this kind of opportunity for leak detection, unless you are bored and place an order in advance, such a price is fleeting, and you ca n’t seize the opportunity simply by hand speed. In fact, at present, many trading platforms have actually adopted corresponding price amplitude filters, which specify the maximum / minimum price range of pending order prices. Oolong trading is very rare. Even if luck hits and catches up, it is very likely that the platform will intervene and the transaction will be rolled back. This situation has not happened before.
Only this time, the trader who had placed an order on Binance for more than a year, even if he successfully leaked and successfully withdrew the coin, it can only be said that he hit the Grand Canal.
Safe moving of bricks
Buying a certain kind of token on a crypto trading platform, and then selling the token to another trading platform, earning the price difference is a moving brick in the crypto circle. Moving bricks has been an arbitrage behavior since the birth of the transaction. It belongs to a very old business. Arthur, the founder of BitMex, who now operates a trading platform, and Xu Mingxing of OKEx, were once members of the army of moving bricks. . This kind of brick moving was the most prosperous at the end of 2017. At that time, trading platforms such as Bithumb in South Korea also called the "Kimchi premium" due to the price difference between other platforms. Moving bricks is a kind of risk-free arbitrage. Players use energy to gain profits, although the single profit is not much. However, with the maturity of trading robots and quantitative trading teams, the spread of tokens between multiple regions or platforms is often wiped out in a matter of seconds. Therefore, the profit margin of manually moving bricks is now very small.
Of course, it is not to say that there is no opportunity. Such an opportunity to make money is indeed hidden under the volatile market.
"Buy at a low price and sell at a high price, this is simply the most secure way to make money in a plunging market!" Investors are excited about cryptography. Starting at 6:30 pm on March 12, cryptocurrencies have experienced sharp fluctuations, while Binance and Huobi When the bitcoin spread between the three trading platforms and OKEx was the largest, it even reached more than 700 US dollars. The discerning player quickly discovered the opportunity, "For half an hour, I made more than 10,000 with a principal of 20,000 yuan. Such an opportunity is usually not available."
Buy and sell orders executed by the above investors at almost the same time, with a spread of nearly $ 450
When it comes to moving bricks, time is money. It is definitely too late to shuttle between multiple trading platforms. Many investors have now transferred the "battlefield" to the platform that focuses on aggregated trading. "The aggregated trading platform integrates the depth of multiple platforms. As long as there is a price difference between supported platforms, users only use One account can be bought and sold on multiple platforms, and it can be operated in a few seconds. "Wu Ling, who seized the opportunity from the extreme market in these two days, made nearly 50,000 by moving bricks in just a few hours. Yuan, the principal is no more than tens of thousands of yuan.
It is understood that there are already multiple platforms targeting the aggregate trading business on the market, and the opportunity to move bricks does not often appear, unless similar to the extreme market appearing in the past few days, or some unique tokens, there may be soaring and plunging. Opportunities, as a whole, are not met a few times a year, and they are fleeting.
However, whether it is MakerDAO auctions, ultra-low-priced pending order transactions, or arbitrage moving bricks under the new situation, these opportunities to make money are actually small probability and cannot be used as conventional investment methods.
These seemingly easy profits are in the end a few people. Many people are trapped in extreme quotes in stuns. Most investors have no assets left on the trading platform overnight.
Maybe this also makes many investors lose confidence in the industry, but in fact, in the face of such a market, after finishing our mood, we are more learning from changes.
Learn the reasons for this disaster, learn the logic of the main control panel, learn what signals were ignored before the disaster, and prepare for the next time. At the same time, we can also see the development of the industry. For example, when all centralized trading platforms are down, DEX can still be implemented despite various problems.
I hope that everyone still has confidence in the blockchain and cryptocurrency industries. Finally, I would like to remind everyone that the recent market changes are unpredictable. Please pay attention to risks and exercise caution.

US Tax Guide for ETH and other cryptocurrencies

Introduction:  
Greetings, fellow ethtraders! Happy New Year! In the next few months, taxpayers across the US will be filing their 2017 tax returns. As an Enrolled Agent and a ETH/cryptocurrency investor and enthusiast, I wanted to write up a brief guide on how your investments in ETH and other cryptocurrencies are taxed in the US.
 
 
1. Are ETH/cryptocurrency realized gains taxable?
Yes. The IRS treats virtual currency (such as cryptocurrency) as property. That means if you sell ETH, BTC, or any other cryptocurrency that has appreciated in value, you have realized a capital gain and must pay taxes on this income. If you held the position for one year or less, it is a short-term capital gain which is taxed at your ordinary income tax rate. If you held the position for more than one year, it is a long-term capital gain which is taxed at your long-term capital gains tax rate. In most cases, this is 15%, but could also be 0% or 20% depending on your specific ordinary income tax bracket.
 
2. If I sell my ETH for USD on Coinbase but do not transfer the USD from Coinbase to my bank account, am I still taxed?
Yes. The only thing that matters is that you sold the ETH, which creates a taxable transaction. Whether you transfer the USD to your bank account or not does not matter.
 
3. If I use my ETH to buy OMG or another cryptocurrency, is this a taxable transaction?
Most likely yes. See #4 below for a more detailed explanation. If assuming crypto to crypto trades are not able to be like-kind exchanged, then continue on to the next paragraph here.
This is actually two different transactions. The first transaction is selling your ETH for USD. The second transaction is buying the OMG with your USD. You must manually calculate these amounts. For example, I buy 1 ETH for $600 on Coinbase. Later on, the price of 1 ETH rises to $700. I transfer that 1 ETH to Bittrex and use it to buy 37 OMG. I have to report a capital gain of $100 because of this transaction. My total cost basis for the 37 OMG I purchased is $700.
 
4. If I use my ETH to buy OMG or other cryptocurrency, could that be considered a tax-free like-kind exchange?
Probably not. The new tax law says that like-kind exchanges only pertain to real estate transactions. This was done with Section 13303, which replaced “property” with “real property” for all of Section 1031 (page 72 near the bottom). My personal interpretation:
In 2018 and going forward, cryptocurrencies can definitely not be like-kind exchanged.
In 2017 and before, it is a very gray area. I personally am not taking the position that they can be like-kind exchanged, because if the IRS went after a taxpayer who did this, the IRS would probably win and the taxpayer would owe taxes, interest, and probably penalties on every single little gain made from trading one cryptocurrency for another.
Here is a great interpretation of why trading cryptocurrency for cryptocurrency is probably not a like-kind transaction.
In my opinion, the biggest factor is that like-kind exchanges must be reported on Form 8824 and not just ignored. Therefore, if a taxpayer is claiming like-kind exchanges on crypto to crypto exchanges, he or she would have to fill out a Form 8824 for each individual transaction of crypto to crypto, which would be absolutely cumbersome if there are hundreds or thousands of such trades.
Here is another article about like-kind exchanges.
Here is the American Institute of CPAs' letter to the IRS, dated June 10, 2016, asking them to release guidance on whether crypto to crypto can be like-kind exchanged or not. The IRS has not responded to the letter.
 
5. How do I calculate the realized capital gain or loss on the sale of my cryptocurrency?
The realized gain or loss is your total proceeds from the sale minus what you purchased those positions for (your cost basis). For example, you bought 1 ETH for $300 in June of 2017. In December of 2017, you sold that 1 ETH for $800. Your realized gain would be $800 - $300 = $500. Since you held it for one year or less, the $500 would be a short-term capital gain taxed at your ordinary income tax rate.
 
6. Which ETH's cost basis do I use if I have multiple purchases?
The cost basis reporting method is up to you. For example, I buy my first ETH at $300, a second ETH at $530, and a third ETH at $400. Later on, I sell one ETH for $800. I can use:
FIFO (first in first out) - cost basis would the first ETH, $300, which would result in a gain of $500.
LIFO (last in first out) - cost basis would be the third ETH, $400, which would result in a gain of $400.
Average cost - cost basis would be the average of the three ETH, $410, which would result in a gain of $390.
Specific identification - I can just choose which coin's cost basis to use. For example, I can choose the second ETH's cost basis, $530, which would result in the lowest capital gains possible of $270.
 
7. If I end up with a net capital loss, can I claim this on my tax return?
Capital gains and capital losses are netted on your tax return. If the net result of this is a capital loss, you may offset it against ordinary income on your tax return, but only at a maximum of $3,000 per year. The remaining losses are carried forward until you use them up.
 
8. What is the tax rate on my capital gains?
If long-term, the tax rate is 0%, 15%, or 20%, depending on your ordinary income tax bracket. If short-term, the tax bracket you’ll be in will depend on your total income and deductions. The ordinary income tax brackets are 10%, 15%, 25%, 28%, 33%, 35%, and 39.6% in 2017 and 10%, 12%, 22%, 24%, 32%, 35%, and 37% in 2018 and going forward.
Here are the 2017 and 2018 ordinary income tax brackets.
Here are the 2017 and 2018 long-term capital gains tax brackets.
Here is a detailed article on how the calculation of long-term capital gains tax work and how you can take advantage of the 0% long-term capital gains rate, if applicable.
 
9. If I mine ETH or any other cryptocurrency, is this taxable?
Yes. IRS Notice 2014-21 states that mining cryptocurrency is taxable. For example, if you mined $7,000 worth of ETH in 2017, you must report $7,000 of income on your 2017 tax return. For many taxpayers, this will be reported on your Schedule C, and you will most likely owe self-employment taxes on this income as well. The $7,000 becomes the cost basis in your ETH position.
 
10. How do I calculate income for the cryptocurrency I mined?
This is the approach I would take. Say I mined 1 ETH on December 31, 2017. I would look up the daily historical prices for ETH and average the high and low prices for ETH on December 31, 2017, which is ($760.35 + $710.12) / 2 = $735.24. I would report $735.24 of income on my tax return. This would also be the cost basis of the 1 ETH I mined.
 
11. Can I deduct mining expenses on my tax return?
If you are reporting the income from mining on Schedule C, then you can deduct expenses on Schedule C as well. You can deduct the portion of your electricity costs allocated to mining, and then you depreciate the cost of your mining rig over time (probably over five years). Section 179 also allows for the full deduction of the cost of certain equipment in year 1, so you could choose to do that if you wanted to instead.
 
12. If I receive ETH or other cryptocurrency as a payment for my business, is this taxable?
Yes. Similar to mining, your income would be what the value of the coins you received was. This would also be your cost basis in the coins.
 
13. If I received Bitcoin Cash as a result of the hard fork on August 1, 2017, is this taxable?
Most likely yes. For example, if you owned 1 Bitcoin and received 1 Bitcoin Cash on August 1, 2017 as a result of the hard fork, your income would be the value of 1 Bitcoin Cash on that date. Bitcoin.tax uses a value of $277. This value would also be your cost basis in the position. Any other hard forks would probably be treated similarly. Airdrops may be treated similarly as well, in the IRS' view.
Here are a couple more good articles about reporting the Bitcoin Cash fork as taxable ordinary income. The second one goes into depth and cites a US Supreme Court decision as precedent: one, two
 
14. If I use ETH, BTC, or other cryptocurrency to purchase goods or services, is this a taxable transaction?
Yes. It would be treated as selling your cryptocurrency for USD, and then using that USD to purchase those goods or services. This is because the IRS treats cryptocurrency as property and not currency.
 
15. Are cryptocurrencies subject to the wash sale rule?
Probably not. Section 1091 only applies to stock or securities. Cryptocurrencies are not classified as stocks or securities. Therefore, you could sell your ETH at a loss, repurchase it immediately, and still realize this loss on your tax return, whereas you cannot do the same with a stock. Please see this link for more information.
 
16. What if I hold cryptocurrency on an exchange based outside of the US?
There are two separate foreign account reporting requirements: FBAR and FATCA.
A FBAR must be filed if you held more than $10,000 on an exchange based outside of the US at any point during the tax year.
A Form 8938 (FATCA) must be filed if you held more than $75,000 on an exchange based outside of the US at any point during the tax year, or more than $50,000 on the last day of the tax year.
The penalties are severe for not filing these two forms if you are required to. Please see the second half of this post for more information on foreign account reporting.
 
17. What are the tax implications of gifting cryptocurrency?
Small gifts of cryptocurrency do not have a tax implication for the gift giver or for the recipient. The recipient would retain the gift giver's old cost basis, so it could be a good idea for the gift giver to provide records of the original cost basis to the recipient as well (or else the recipient would have to assume a cost basis of $0 if the recipient ever sells the cryptocurrency).
Large gifts of cryptocurrency could start having gift and estate tax implications on the giver if the value exceeds more than $14,000 (in 2017) or $15,000 (in 2018) per year per recipient.
Here's a good article on Investopedia on this issue.
An important exception applies if the gift giver gives cryptocurrency that has a cost basis that is higher than the market value at the time of the gift. Please see the middle of this post for more information on that.
 
18. Where can I learn even more about cryptocurrency taxation?
Unchained Podcast: The Tax Rules That Have Crypto Users Aghast
IRS Notice 2014-21
Great reddit post from tax attorney Tyson Cross from 2014
 
19. Are there any websites that you recommend in helping me with all of this?
Yes - I have used bitcoin.tax and highly recommend it. You can import directly from an exchange to the website using API, and/or export a .csv/excel file from the exchange and import it into the website. The exchanges I successfully imported from were Coinbase, GDAX, Bittrex, and Binance. The result is a .csv or other file that you can import into your tax software.
I have also heard good things about cointracking.info but have not personally used it myself.
 
20. Taxation is theft!
I can't help you there.
 
 
That is the summary I have for now. There have been a lot of excellent cryptocurrency tax guides on reddit, such as this one, this one, and this one, but I wanted to post my short summary guide on ethtrader which hopefully answers some of the questions you all may have about US taxation of ETH and other cryptocurrencies. Please let me know if you have any more questions, and I’d be happy to answer them to the best of my ability. Thank you!
Regarding edits: I have made many edits to my post since I originally posted it. Please refresh to see the latest edits to my guide. Thank you.
