According to CoinDesk, the U.S. Department of the Treasury's Financial Crimes Enforcement Network (FinCEN) is proposing to label crypto mixers as a "primary money laundering concern" in its effort to combat illicit crypto finance. The proposal highlights the terrorist groups that have benefited from anonymous crypto funds, including possibly Hamas. FinCEN issued a notice of proposed rulemaking on Thursday, which will be open to public comment for 90 days.Deputy Secretary of the Treasury Wally Adeyemo said in a statement, “Today’s action underscores Treasury’s commitment to combating the exploitation of Convertible Virtual Currency mixing by a broad range of illicit actors, including state-affiliated cyber actors, cyber criminals, and terrorist groups.” The statement cited the agency's past actions against Tornado Cash and Blender.io as examples of its commitment to fighting illicit crypto activities.
