We are pleased to introduce the third edition of The Virtual Currency Regulation Review (the Review). The increased acceptance and use of virtual currencies by businesses and the exponential growth of investment opportunities for speculators marked late 2019 and early 2020. In 2019, it was reported that several of the largest global banks were developing a digital cash equivalent of central bank-backed currencies that would be operated via blockchain technology, and that Facebook was developing its own virtual currency pegged to the US dollar – Libra – to be used to make payments by people without bank accounts and for currency conversions. In 2019, the US House of Representatives' Committee on Financial Services held a hearing on the potential impact of Libra in which one witness testified that Libra posed a fundamental threat to the ability of sovereign nations to maintain distinct monetary policies and respond to currency crises.

The Review is a country-by-country analysis of developing regulatory initiatives aimed at fostering innovation, while at the same time protecting the public and mitigating systemic risk concerning trading and transacting in virtual currencies. In February 2020, the International Organizations of Securities Commissions (IOSCO) published a final report titled 'Issues, Risks and Regulatory Considerations Relating to Crypto-Asset Trading Platforms'. The final report describes issues and risks identified to date that are associated with the trading of cryptoassets on cryptoasset trading platforms (CTPs). In relation to the issues and risks identified, the report describes key considerations and provides related toolkits that are useful for each consideration. The key considerations relate to: (1) access to CTPs; (2) safeguarding participant assets; (3) conflicts of interest; (4) operations of CTPs; (5) market integrity; (6) price discovery; and (7) technology. IOSCO advised that these seven key considerations (and the related toolkits described in the report) represent specific areas that IOSCO believes jurisdictions could consider in the context of the regulation of CTPs.

Fortunes have been made and lost in the trading of virtual currencies since Satoshi Nakamoto published a white paper in 2008 describing what he referred to as a system for peer-to-peer payments, using a public decentralised ledger known as a blockchain and cryptography as a source of trust to verify transactions. That paper, released in the dark days of a growing global financial market crisis, laid the foundations for Bitcoin, which would become operational in early 2009. Satoshi has never been identified, but his white paper represented a watershed moment in the evolution of virtual currency. Bitcoin was an obscure asset in 2009, but it is far from obscure today, and there are now many other virtual currencies and related assets. In 2013, a new type of blockchain that came to be known as Ethereum was proposed. Ethereum's native virtual currency, Ether, went live in 2015 and opened up a new phase in the evolution of virtual currency. Ethereum provided a broader platform, or protocol, for the development of all sorts of other virtual currencies and related assets.

In 2020, the global outbreak of the novel coronavirus (or covid-19) impacted virtually every person on the planet and had severe and sudden effects on every major economy. At the time of writing, the pandemic is ongoing and, while some locations are pushing past their respective 'peaks' of infection, cities that are central to the global financial markets, such as New York City, remain under strict lockdown orders, with many workers in the financial services sector working remotely. It is unclear when these cities will return to a version of 'normal'. In the midst of all this chaos, there is a natural experiment under way in the cryptocurrency markets. We are perhaps learning what happens when our governments are strained and their competence is questioned. Since mid-March 2020, when the pandemic hit the United States in earnest (it had already been raging in China, Italy, Iran, etc.), the price of Bitcoin has gone up in essentially a straight line – from approximately US$5,000 to almost US$10,000 as at mid-May. Now, to be fair, this follows a significant price decline preceding March, but it is at least interesting to observe that the most widely held cryptocurrency is weathering a significant economic storm with apparent ease.

When we first launched the Review three years ago, we were optimistic but sceptical about whether virtual currencies would be widely and consistently in commercial use. However, the virtual currency revolution has come a long way and has endured a sufficient number of events that could or should have been fatal for the asset class. Our confidence in the long-term viability of virtual currency has only increased over the previous year. Virtual currencies and the blockchain and other distributed ledger technology on which they are based are groundbreaking, and are being deployed right now in many markets and for many purposes. As lawyers, we must now endeavour to understand what that means for our clients.

Virtual currencies are borderless: they exist on global and interconnected computer systems. They are generally decentralised, meaning that the records relating to a virtual currency and transactions therein may be maintained in a number of separate jurisdictions simultaneously. The borderless nature of this technology was the core inspiration for the Review. As practitioners, we cannot afford to focus solely on our own jurisdictional silos. For example, a US banking lawyer advising clients on matters related to virtual currency must not only have a working understanding of US securities and derivatives regulation; he or she must also have a broad view of the regulatory treatment of virtual currency in other major commercial jurisdictions.

Global regulators have taken a range of approaches to responding to virtual currencies. Some regulators have attempted to stamp out the use of virtual currencies out of a fear that virtual currencies such as Bitcoin allow capital to flow freely and without the usual checks that are designed to prevent money laundering and the illicit use of funds. Others have attempted to write specific laws and regulations tailored to virtual currencies. Still others – the United States included – have attempted to apply legacy regulatory structures to virtual currencies. Those regulatory structures attempt what is essentially 'regulation by analogy'. In some countries, a virtual currency, which is not a fiat currency, may be regulated in the same manner as money; in other countries, virtual currency may be regulated similarly to securities or commodities. We make one general observation at the outset: there is no consistency across jurisdictions in their approach to regulating virtual currencies. Perhaps the efforts of IOSCO will help to change that going forward, but there is currently no widely accepted global regulatory standard. That is what makes a publication such as the Review both so interesting and so challenging.

The lack of global standards has led to a great deal of regulatory arbitrage, as virtual currency innovators shop for jurisdictions with optimally calibrated regulatory structures that provide an acceptable amount of legal certainty and virtual currency scofflaws shop for jurisdictions with regulatory structures that provide no meaningful regulation. While some market participants are interested in finding the jurisdiction with the lightest touch (or no touch), most legitimate actors are not attempting to flee from regulation entirely. They appreciate that regulation is necessary to allow virtual currencies to achieve their potential, but they do need regulatory systems with an appropriate balance and a high degree of clarity. The technology underlying virtual currencies is complex enough without adding layers of regulatory complexity into the mix.

It is perhaps ironic that the principal source of strength of virtual currencies – decentralisation – is the same characteristic that the regulators themselves seem to be displaying. There is no central authority over virtual currencies, either within or across jurisdictions, and each regulator takes an approach that seems appropriate to that regulator based on its own narrow view of the markets and legacy regulations. Again, we are hopeful that IOSCO's efforts will help to encourage the emergence of optimal regulatory structures over time. Ultimately, the borderless nature of these markets allows market participants to 'vote with their feet', and they will gravitate towards jurisdictions that achieve the right regulatory balance of encouraging innovation and protecting the public and the financial system. It is much easier to do this in a primarily electronic and computerised business than it would be in a brick-and-mortar business. Computer servers are relatively easy to relocate; factories and workers are less so.

The third edition of the Review provides a practical analysis of recent legal and regulatory changes and developments, and of their effects, and looks forward to expected trends in the area of virtual currencies on a country-by-country basis. It is not intended to be an exhaustive guide to the regulation of virtual currencies globally or in any of the included jurisdictions. Instead, for each jurisdiction, the authors have endeavoured to provide a sufficient overview for the reader to understand the current legal and regulatory environment at a high level.

Virtual currency is the broad term that is used in the Review to refer to Bitcoin, Ether, Tethers and other stablecoins, cryptocurrencies, altcoins, ERC20 tokens, digital, virtual and crypto assets, and other digital and virtual tokens and coins, including coins issued in initial coin offerings. We recognise that in many instances the term 'virtual currency' will not be appropriate, and other related terms are used throughout as needed. In the law, the words we use matter a great deal, so, where necessary, the authors of each chapter provide clarity around the terminology used in their jurisdiction and the legal meaning given to that terminology.

Based on feedback on the first and second editions of the Review from members of the legal community throughout the world, we are confident that attorneys will find the updated third edition to be an excellent resource in their own practices. We are still in the early days of the virtual currency revolution, but it does not appear to be a passing fad. The many lawyers involved in this treatise have endeavoured to provide as much useful information as practicable concerning the global regulation of virtual currencies.

The editors would like to extend special thanks to Ivet Bell (New York) and Dan Applebaum (Chicago), both Sidley Austin LLP associates, for their invaluable assistance in organising and editing the third edition of the Review, and particularly the United States chapter. The assembly of this third edition is made all the more remarkable by the fact that many of the authors and contributors are working from home, with dogs barking in the background and children at their feet. Special thanks go out to all those dogs and children for being as tolerant as possible as we try to conduct the work of busy lawyers and also produce this Review.
