The Financial Crimes Enforcement Network (FinCEN) is a bureau of the United States Department of the Treasury that collects and analyzes information about financial transactions in order to combat domestic and international money laundering, terrorist financing, and other financial crimes. 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. Jennifer Shasky Calvery, director of FinCEN said, "Virtual currencies are subject to the same rules as other currencies.  Basic money services business rules apply here."
