The United States Treasury Department's Financial Crimes Enforcement Network, or FinCEN, has proposed designating cryptocurrency mixing as an area of "primary money laundering concern" following Hamas’ attack on Israel.
In an Oct. 19 notice, FinCEN said it had assessed that "the percentage of CVC [convertible virtual currencies] transactions processed by CVC mixers that originated from likely illicit sources is increasing". FinCEN proposed requiring domestic financial institutions and agencies to "implement certain recordkeeping and reporting requirements" for transactions involving crypto mixers.
