The U.K. government is actively seeking to curb criminal behaviour that utilises crypto, such as money laundering and terrorism financing. All U.K.-based crypto firms must comply with Anti-Money Laundering and Counter-Terrorist Financing laws and are required to register with the U.K. financial regulator, the Financial Conduct Authority (FCA), in order to operate legally. Many firms have not yet registered. Recently, the FCA warned consumers against dealing with more than 100 crypto companies that are not registered with the FCA. A list of unregistered firms has been provided to enable investors to determine whether a firm they intend to deal with is non-compliant.
