FBI warns against using unlicensed crypto transfer services

The FBI warned that using unlicensed cryptocurrency transfer services can lead to financial loss when law enforcement targets and seizes non-compliant platforms. The advisory urges users to verify MSB registration, prefer KYC-compliant services, and avoid apps or services known to facilitate criminal laundering. The notice follows the takedown of Samourai — whose domains and app were seized and whose founders were charged with laundering large sums — underscoring the risk that unregulated crypto transfer and mixing services pose to users and the broader financial system.
