On August 5th, Yaya J. Fanusie, a part-time researcher at the Defense Democracy Foundation and chief strategist at Cryptocurrency AML Strategies, LLC, said that the US is not the leader in encryption regulation. On the contrary, from the perspective of anti-money laundering (AML) regulation, the United States is undoubtedly the leader. As early as 2013, the United States provided formal guidance on how to regulate cryptocurrency transactions. Last year, I collaborated with Elliptic's Tom Robinson on a study to analyze bitcoin transaction data from various bitcoin conversion services around the world. We found that the proportion of illegal bitcoins from the dark-net market and mixers entering North America's exchanges was much lower than in Europe. The likely reason is that FinCEN, the organization that implements anti-money laundering regulations by the US Treasury, provides clearer guidance than Europe. Another example of the US leadership role in cryptocurrency AML regulation is that the Global Institutional Financial Action Task Force (FATF), which sets standards for anti-money laundering and counter-terrorism financing, has recently provided guidance for regulating digital assets. This guideline is driven by the United States and largely reflects the framework that FinCEN has implemented.
