We are pleased to introduce the second 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 2018 and early 2019. As examples, in May 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 to be used to make payments by people without bank accounts and for currency conversions.

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. On 28 May 2019, the International Organizations of Securities Commissions (IOSCO) published a report titled 'Issues, Risks and Regulatory Considerations Relating to Cryptoassets'. This report provided guidance on the unique issues concerning overseeing cryptoasset trading platforms that provide onboarding, clearing, settlement, custody, market making and advisory services for investors under the umbrella of a single venue. IOSCO advised global regulators of these platforms that their goals should be to ensure that investors are protected, fraud and manipulation are prevented, cryptoassets are sold in a fair way and systemic risk is reduced – the same goals that apply to securities regulation. IOSCO also advised that national regulators should share information, monitor market abuse, take enforcement actions against cryptoasset trading platforms when appropriate and ensure that these venues are resilient to cyberattacks. In the United States, the US Securities and Exchange Commission has not yet approved public offerings of virtual currency exchange-traded funds. The US Commodity Futures Trading Commission (CFTC) has approved of virtual currency futures trading on regulated exchanges and the trading of virtual currency swaps on regulated swap executed facilities. US regulators remain concerned about potential abuses and manipulative activity concerning virtual currencies, including the proliferation of fraudulent virtual currency Ponzi schemes. In May 2019, the US Financial Crimes Enforcement Network issued guidance concerning the application of bank secrecy laws relating to financial institutions with respect to identifying and reporting suspicious activities by criminals and other bad actors who exploit convertible virtual currencies (virtual currencies whose values can be substituted for fiat currencies) for illicit purposes. The CFTC also issued an alert offering potential whistle-blower rewards to members of the public who report virtual currency fraud or manipulation to the CFTC.

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.

Whether virtual currencies will be widely and consistently in commercial use remains uncertain. However, the virtual currency revolution has now come far enough and has endured a sufficient number of potentially fatal events that we are confident virtual currency in some form is here to stay. Virtual currencies and the blockchain and other distributed ledger technology on which they are based are real, and are being deployed right now in many markets and for many purposes. These technologies are being put in place in the real world, and we as lawyers must now endeavour to understand what that means for our clients.

Virtual currencies are essentially 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'. For example, a virtual currency, which is not a fiat currency, may be regulated in the same manner as money, or in the same manner as a security or commodity. We make one general observation at the outset: there is no consistency across jurisdictions in their approach to regulating virtual currencies. That is, 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 to assemble.

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. 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 and 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. We believe optimal regulatory structures will emerge and converge over time. Ultimately, the borderless nature of these markets allows market participants to 'vote with their feet', and they will gravitate toward 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 bricks-and-mortar business. Computer servers are relatively easy to relocate; factories and workers are less so.

The second 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.

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 cryptoassets, 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 edition of the Review from members of the legal community throughout the world, we are confident that attorneys will find the updated second 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 second edition of the Review, and particularly the United States chapter.
