According to a senior official, the cryptocurrency industry must follow the US Treasury Department’s anti-money-laundering and sanctions regulations to prevent bad actors from using platforms known as “mixers” to launder illicit funds. Mixers, which allow users to exchange cryptocurrencies anonymously, can be used by illicit actors to conceal the ownership and movement of funds while making it more difficult for law enforcement to monitor the transfers, according to Elizabeth Rosenberg, the Treasury assistant secretary for terrorist financing and financial crimes, in a speech Friday.
