Recently, governments and international organizations have intensified their efforts to combat the use of cryptocurrency mixers. In some countries, laws have been introduced that ban the operation of such services. Financial regulators require exchanges and other participants in the cryptocurrency market to comply with Anti-Money Laundering (AML) rules and Know Your Customer (KYC) procedures, making the use of mixers more difficult.
Additionally, law enforcement agencies are conducting operations to arrest operators of cryptocurrency mixers and shut down such platforms. For example, in 2021, several major cryptocurrency mixers in Europe were shut down, signaling to criminals the increasing control over their activities. One of the blocked mixers was the largest mixer on the Ethereum network, Tornado Cash.
