"This report summarizes the cryptocurrency policies and regulatory regimes in fourteen jurisdictions around the world. Among the key issues covered in the report are matters relating to the legality of cryptocurrency markets; the tax treatment of cryptocurrencies; and the applicability of anti-money laundering, anti-organized crime, and anti-terrorism-financing laws. [...] Many of the countries that permit cryptocurrency markets to operate have enacted laws subjecting organizations that participate in these markets to rules designed to prevent money-laundering, terrorism financing, and organized crime. These include Australia, Belarus, Canada, Gibraltar, Japan, Jersey, and Switzerland. While a bill that would have the same effect is working its way through the Brazilian legislative process, countries like Argentina, France, and Mexico have yet to follow suit."
