Swiss and German authorities have jointly shut down Cryptomixer.io, a major Bitcoin mixing service long associated with cybercrime and money laundering. The coordinated operation, executed on Wednesday and announced December 1, resulted in the seizure of servers, over 12 terabytes of data, and more than €25 million (approximately $29 million) in Bitcoin.
A Major International Takedown
According to German federal investigators (BKA), the operation was carried out with regional prosecutors in Frankfurt and law enforcement in Zurich. Cryptomixer.io, active since 2016, reportedly processed billions of euros tied to criminal activity.
Crypto mixing platforms function by breaking large cryptocurrency transfers into smaller parts and blending them with unrelated transactions, making it extremely difficult to trace funds. For years, this technique has been widely used in ransomware operations, darknet market payments, and cross-border money laundering.
Authorities seized the platform’s servers in Switzerland and took control of the cryptomixer.io domain. The data haul, exceeding 12 terabytes, is expected to fuel ongoing investigations into global cybercrime networks.
Why This Crackdown Matters
Europol confirmed its involvement and described Cryptomixer.io as a key infrastructure provider for ransomware gangs and organized cybercriminal groups. The service was accessible both on the regular web and the dark web, making it a widely used laundering route for illicit Bitcoin.
The takedown marks another step in Europe’s tightening stance against crypto-enabled crime. It also demonstrates increasing cross-border coordination between Swiss, German, EU, and U.S. agencies to dismantle the supporting infrastructure behind digital financial crimes.
With Cryptomixer.io offline, investigators expect ripple effects across cybercrime operations that depended heavily on mixing services to hide funds.
