The US Treasury Department is actively seeking expanded enforcement powers from Congress to address concerns over the use of cryptocurrency in illicit finance by foreign providers of crypto services. This move is aimed at enhancing the department's ability to combat the misuse of crypto services by foreign entities, particularly those from countries like Iran, Russia, and North Korea, which pose a 'crypto risk to national security'. Treasury officials have emphasized the need for 'necessary tools' to fight crypto-linked illicit finance, highlighting the growing challenge of regulating the digital currency space and outlining proposals for tighter crypto crime control.
