Illegal "Cryptomixer" Dismantled by Law Enforcement

With the support of Europol, law enforcement officers from Germany and Switzerland have dismantled the money laundering platform "Cryptomixer". The crime fighters were able to seize the domain and servers.

As Europol reports, the joint "Operation Olympia" ran from November 24 to 28, 2025. The BKA dates the operation to last Wednesday, November 26, 2025. The investigators focused on shutting down the illegal cryptocurrency mixer "Cryptomixer". This is a service that mixes cryptocurrencies to obscure the source and destination of transactions, thus anonymizing them. Simply put, they throw the users' coins into a pot and redistribute them from there to the depositors. Criminals use this for money laundering.

Extensive Seizures

Law enforcement investigators were able to seize cryptocurrencies worth around 25 million euros. In addition, they secured the infrastructure located in Switzerland, mail accounts, and the domain "cryptomixer.io". They were also able to secure evidence located on a file hosting service and deactivate the associated account. The website of the illegal service is now adorned with a seizure banner from the law enforcement authorities.

The officers explain that "cryptomixer.io" was considered one of the largest Bitcoin mixers, recording billions in turnover, "most of which was of criminal origin". Europol has recorded turnover of 1.3 billion euros since its founding year. The platform has existed since 2016. It enabled anonymous deposits and withdrawals, thus obscuring financial flows. The traceability was further complicated by the lack of measures to identify customers. It was accessible in both the clear and dark web.

At the beginning of the year, law enforcement investigators, with the support of Europol, shut down two cybercrime forums with around 10 million users. Authorities are repeatedly achieving investigative successes against online crime. Cybercriminals should therefore not feel too secure.
