On September 20, the Colorado Department of Regulatory Agencies Division of Banking (Division) issued interim guidance exempting certain types of cryptocurrency exchanges from the state’s money transmitter licensing requirements. Under the interim guidance—which outlines the Division’s interpretation of Colorado’s existing Money Transmitters Act (the Act)— the Division determined that the Act regulates the transmission of money, meaning legal tender, and that cryptocurrencies are not legal tender under the Act. As a result, virtual currency exchanges operating in Colorado do not require a license if transmitting only cryptocurrencies without any legal tender issued and backed by a government (fiat currency) involved in the transaction. However, if fiat currency is present in a transaction, then a virtual currency exchange may require a license. Additionally, a virtual currency exchange must obtain a license when it performs all of the following: (i) it engages in the business of selling and buying cryptocurrencies for fiat currency; (ii) it allows a Colorado customer to transfer cryptocurrency to another customer within the exchange; and (iii) it allows the transfer of fiat currency through the medium of cryptocurrency within the exchange. If a virtual currency exchange offers the ability to transfer fiat currency through the medium of cryptocurrency, the Division encourages the exchange to contact the Division to determine whether it must obtain a license.
