On March 18, 2013 FinCEN issued a guidance regarding virtual currencies, according to which, exchangers and administrators, but not users of convertible virtual currency are considered money transmitters, and must comply with rules to prevent money laundering/terrorist financing ("AML/CFT") and other forms of financial crime, by record-keeping, reporting and registering with FinCEN.
