Swiss and German agencies have taken down Cryptomixer.io, a major service used to hide illegal Bitcoin transactions.
Swiss and German Authorities Shut Down Cryptomixer.io
Cryptomixer.io—launched in 2016—had long operated as one of the world’s largest Bitcoin-mixing services, reportedly generating billions of euros in revenue, the majority stemming from criminal transactions. Crypto-mixing platforms function by fragmenting digital payments and blending them with unrelated funds, creating layers of obfuscation that make illicit money flows nearly impossible to trace.
In a major international crackdown led by Zurich law-enforcement authorities, investigators seized the platform’s servers in Switzerland, took control of the cryptomixer.io domain, and confiscated more than 12 terabytes of operational data, along with over €25 million ($29 million) worth of Bitcoin. Officials say the data haul provides a rare window into global criminal finance operations.
Germany’s Federal Criminal Police Office (BKA) said the evidence will “significantly support ongoing investigations into wider cybercrime networks,” noting that the operation was supported by Europol and multiple U.S. and EU cybersecurity and financial-crime agencies.
Europol, in a separate statement, emphasized that Cryptomixer.io had facilitated a broad range of illicit activities—including ransomware payouts and money laundering—and operated openly on both the regular internet and the dark web, making it a preferred tool for criminal organizations seeking anonymity.
