Authorities do have some success in tracking and catching criminals who wash their funds via crypto. In July 2021, UK police seized roughly $250 million US of crypto used for money laundering. This seizure was the largest to date in the UK of crypto funds, beating a previous UK record of $158 million set just weeks before.
In the same month, $33 million was seized by Brazilian authorities in a sophisticated money-laundering operation. Two individuals and 17 companies were involved in purchasing crypto to hide illegally sourced funds. The criminal organization involved set up the companies with this sole purpose in mind. The cryptocurrency exchanges also cooperated with the criminal organizations knowingly and did not follow correct AML procedures.
