Quintenz, Commissioner, U.S. Commodity Futures Trading Commission ABA BUSINESS LAW SECTION DERIVATIVES & FUTURES LAW COMMITTEE 2018 WINTER MEETING NEW PRODUCTS / FIN TECH PANEL 2017 Developments in US Regulation of Virtual Currencies and Related Products: Yin and Yang January 5, 2018 By Katherine Cooper1 2017 was a year during which virtual currencies began to move into the mainstream financial markets. This generated significant legal and regulatory developments as U.S. regulators faced numerous novel products attempting to blend the old with the new. Although facing so many novel issues, the regulators’ responses tell a familiar story of the struggle to balance the yin of customer protection with the yang of encouraging financial innovation and competition. Below is a summary of 2017 developments from the SEC, CFTC, OCC, FinCEN and the States. I. Securities and Exchange Commission a. Bitcoin Exchange-Traded Products A number of sponsors of proposed Bitcoin exchange traded products had applications for approval pending before the Securities and Exchange Commission at the beginning of 2017. In March 2017, the SEC rejected a proposal backed by Tyler and Cameron Winklevoss.2 The Bats Exchange proposed a rule amendment which would list the shares of the Winklevoss Bitcoin Trust for trading. -
Rev. Rul. 2019-24 ISSUES (1) Does a Taxpayer Have Gross Income Under
26 CFR 1.61-1: Gross income. (Also §§ 61, 451, 1011.) Rev. Rul. 2019-24 ISSUES (1) Does a taxpayer have gross income under § 61 of the Internal Revenue Code (Code) as a result of a hard fork of a cryptocurrency the taxpayer owns if the taxpayer does not receive units of a new cryptocurrency? (2) Does a taxpayer have gross income under § 61 as a result of an airdrop of a new cryptocurrency following a hard fork if the taxpayer receives units of new cryptocurrency? BACKGROUND Virtual currency is a digital representation of value that functions as a medium of exchange, a unit of account, and a store of value other than a representation of the United States dollar or a foreign currency. Foreign currency is the coin and paper money of a country other than the United States that is designated as legal tender, circulates, and is customarily used and accepted as a medium of exchange in the country of issuance. See 31 C.F.R. § 1010.100(m). - 2 - Cryptocurrency is a type of virtual currency that utilizes cryptography to secure transactions that are digitally recorded on a distributed ledger, such as a blockchain. Units of cryptocurrency are generally referred to as coins or tokens. Distributed ledger technology uses independent digital systems to record, share, and synchronize transactions, the details of which are recorded in multiple places at the same time with no central data store or administration functionality. A hard fork is unique to distributed ledger technology and occurs when a cryptocurrency on a distributed ledger undergoes a protocol change resulting in a permanent diversion from the legacy or existing distributed ledger. -

Blockchain Law: the Fork Not Taken
Blockchain Law The fork not taken Robert A. Schwinger, New York Law Journal — November 24, 2020 I shall be telling this with a sigh Somewhere ages and ages hence: Two roads diverged in a wood, and I— I took the one less traveled by, And that has made all the difference. — Robert Frost Is the token holder — often the holder of some form of digital currency — always free to choose which branch of the fork to take? A blockchain is often envisioned as a record of a single continuous Background: ‘Two roads diverged in a sequential series of transactions, like the links of the metaphorical chain from which the term “blockchain” derives. But sometimes yellow wood’ the chain turns out to be not so single or continuous. Sometimes situations can arise where a portion of the chain can branch off A blockchain fork occurs when someone seeks to divide a into a new direction from the original chain, while the original chain blockchain into two branches by changing its source code, which also continues to move forward separately. This presents a choice is possible to do because the code is open. For those users who for the current holders of the digital tokens on that blockchain choose to upgrade their software, the software then “rejects about which direction they wish to follow going forward. In the all transactions from older software, effectively creating a new world of blockchain, this scenario is termed a “fork.” branch of the blockchain. However, those users who retain the old software continue to process transactions, meaning that But is the tokenholder—often the holder of some form of digital there is a parallel set of transactions taking place across two currency—always free to choose which branch of the fork to different chains.” See generally N. -

A Survey on Volatility Fluctuations in the Decentralized Cryptocurrency Financial Assets
Journal of Risk and Financial Management Review A Survey on Volatility Fluctuations in the Decentralized Cryptocurrency Financial Assets Nikolaos A. Kyriazis Department of Economics, University of Thessaly, 38333 Volos, Greece; [email protected] Abstract: This study is an integrated survey of GARCH methodologies applications on 67 empirical papers that focus on cryptocurrencies. More sophisticated GARCH models are found to better explain the fluctuations in the volatility of cryptocurrencies. The main characteristics and the optimal approaches for modeling returns and volatility of cryptocurrencies are under scrutiny. Moreover, emphasis is placed on interconnectedness and hedging and/or diversifying abilities, measurement of profit-making and risk, efficiency and herding behavior. This leads to fruitful results and sheds light on a broad spectrum of aspects. In-depth analysis is provided of the speculative character of digital currencies and the possibility of improvement of the risk–return trade-off in investors’ portfolios. Overall, it is found that the inclusion of Bitcoin in portfolios with conventional assets could significantly improve the risk–return trade-off of investors’ decisions. Results on whether Bitcoin resembles gold are split. The same is true about whether Bitcoins volatility presents larger reactions to positive or negative shocks. Cryptocurrency markets are found not to be efficient. This study provides a roadmap for researchers and investors as well as authorities.

Segwit2x –
SegWit2x – A New Statement The Overwhelming power of SegWit2x In order to safeguard the community from an undesired chain split, the upgrade should be overwhelming, but it’s not enough. It should also ‘appear’ as overwhelming. People, businesses and services needs to be certain about what is going to happen and the risks if they won’t follow. My impression is that still too many speaking english people in the western world think the upgrade will be abandoned before or immediately after block 494784 is mined, thus they are going to simply ignore it. That could lead to unprepared patch up and confusion, while naïve users risk to harm themselves. For this reason and for the sake of the Bitcoin community as a whole, we need to show again, clearly and publicly the extent of the support to SegWit2x. We also need to commit ourselves in a widespread communication campaign. I know this is not a strict technical matter, but it could help a lot avoiding technical issues in the future. What we have to do First, we need a new statement from the original NYA signers and all the business, firms and individuals who joined the cause later. That statement should be slightly different from the original NYA though, and I am explaining why. We all know that what Bitcoin is will be ultimately determined by market forces, comprehensive of all the stakeholders involved: businesses, miners, users, developers, traders, investors, holders etc. Each category has its own weight in the process, and everybody has incentives in following the market. -
MYBTGWALLET SCAM the Dark Side of the Fork
MYBTGWALLET SCAM The dark side of the fork Intro After Bitcoin Cash fork on Aug. 1st, Bitcoin was involved in two other forks between October and November: before the so disputed Segwit2x announced fork, on Oct. 24th a new crypto was launched. Bitcoin Gold was a new greedy chance for Bitcoin owners to earn some free money: importing mnemonic seeds or private keys belonging to a BTC wallet in a BTG one they had the opportunity to redeem their free BTG. This was possible through local BTG clients or through some web services such as MyBTGWallet.com, a website listed directly on BTG official webpage. This particular case turned in a scam that stole an impressive number of Bitcoin from “unexperienced” users. The Scam Site MyBTGWallet scam worked in a very simple way: users imported the mnemonic seed of their BTC wallet on the scam page providing in this way the scammer with the private keys needed to steal the balance of bitcoin still on the wallet and any other cryptocurrencies stored on the same wallet (e.g. Ethereum or Litecoin in case it was a multicurrency wallet). MyBTGWallet page The site used a clever trick to save the mnemonic seed into the cookies of the browser and then siphoned the cookies via a google tracking javascript having this way access to all seeds checked on the website. 2 The numbers The website was used by many bitcoin holders after the fork happened. The scammers progressively moved the stolen funds to other bitcoin addresses. Thanks to open source intelligence activities, we were able to create the clusters of the stolen bitcoin and determine that the number of compromised addresses is almost 4500. -

Trading and Arbitrage in Cryptocurrency Markets
Trading and Arbitrage in Cryptocurrency Markets Igor Makarov1 and Antoinette Schoar∗2 1London School of Economics 2MIT Sloan, NBER, CEPR December 15, 2018 ABSTRACT We study the efficiency, price formation and segmentation of cryptocurrency markets. We document large, recurrent arbitrage opportunities in cryptocurrency prices relative to fiat currencies across exchanges, which often persist for weeks. Price deviations are much larger across than within countries, and smaller between cryptocurrencies. Price deviations across countries co-move and open up in times of large appreciations of the Bitcoin. Countries that on average have a higher premium over the US Bitcoin price also see a bigger widening of arbitrage deviations in times of large appreciations of the Bitcoin. Finally, we decompose signed volume on each exchange into a common and an idiosyncratic component. We show that the common component explains up to 85% of Bitcoin returns and that the idiosyncratic components play an important role in explaining the size of the arbitrage spreads between exchanges. ∗Igor Makarov: Houghton Street, London WC2A 2AE, UK.

Blockchain Consensus: an Analysis of Proof-Of-Work and Its Applications. Amitai Porat1, Avneesh Pratap2, Parth Shah3, and Vinit Adkar4
Blockchain Consensus: An analysis of Proof-of-Work and its applications. Amitai Porat1, Avneesh Pratap2, Parth Shah3, and Vinit Adkar4 [email protected] [email protected] [email protected] [email protected] ABSTRACT Blockchain Technology, having been around since 2008, has recently taken the world by storm. Industries are beginning to implement blockchain solutions for real world services. In our project, we build a Proof of Work based Blockchain consensus protocol and evauluate how major applications can run on the underlying platform. We also explore how varying network conditions vary the outcome of consensus among nodes. Furthermore, to demonstrate some of its capabilities we created our own application built on the Ethereum blockchain platform. While Bitcoin is by and far the first major cryptocurrency, it is limited in the capabilities of its blockchain as a peer-to-peer currency exchange. Therefore, Ethereum blockchain was the right choice for application development since it caters itself specifically to building decentralized applications that seek rapid deployment and security. 1 Introduction Blockchain technology challenges traditional shared architectures which require forms of centralized governance to assure the integrity of internet applications. It is the first truly democratized, universally accessible, shared and secure asset control architecture. The first blockchain technology was founded shortly after the US financial collapse in 2008, the idea was a decentralized peer-to-peer currency transfer network that people can rely on when the traditional financial system fails. As a result, blockchain largely took off and made its way into large public interest. We chose to investigate the power of blockchain consensus algorithms, primarily Proof of Work. -
