FinCEN issues its first virtual-currency guidance (FIN-2013-G001)
The Treasury Department's Financial Crimes Enforcement Network published the first U.S. guidance on virtual currencies. Individual users are not money services businesses, but administrators and exchangers are money transmitters and therefore regulated.
Impact: Exchanges and exchangers took on registration, reporting and recordkeeping duties. It was the first document in which a U.S. regulator addressed Bitcoin explicitly.
