Europol Unplugs Cryptomixer in Major Takedown of $1.4B Bitcoin Laundering Hub

01. Dec 2025 Posted by Laurent C. on News

European authorities have dismantled Cryptomixer, a long-running crypto mixing platform responsible for laundering more than $1.4 billion (€1.3 billion) in Bitcoin since 2016. The coordinated operation—led by Germany and Switzerland with support from Europol and Eurojust—resulted in the seizure of over $27 million (€25 million) in BTC, three servers, and 12 terabytes of data during a takedown in Zurich last week.

The platform’s domain, cryptomixer.io, was seized and replaced with an official banner after investigators shut down operations across both the clear web and dark web, according to Europol.

Crypto mixers like Cryptomixer work by pooling and shuffling cryptocurrency deposits before returning unlinked coins, masking their origins and enabling large-scale money laundering. Authorities say the service acted as a laundering hub for ransomware groups, dark-web marketplaces, underground forums, and operations tied to drug trafficking, weapons sales, payment-card fraud, and more.

Investigators noted that Cryptomixer’s years-long activity underscored its operational maturity, reliability, and reputation in illicit circles. Its sudden shutdown is expected to cause immediate disruptions—delayed withdrawals, stuck funds, and frantic shifts—as criminal groups scramble for new laundering routes. Still, law enforcement cautions that such activity typically migrates to other mixers, cross-chain bridges, or high-risk exchanges within weeks.

Europol coordinated the action through the Joint Cybercrime Action Taskforce (J-CAT) in The Hague, providing on-site forensic support and facilitating cross-border intelligence sharing.

The move follows Europol’s March 2023 takedown of ChipMixer and reflects a continuing continental crackdown on crypto-enabled crime. Recent related operations include:

  • Earlier this month: Police in Cyprus, Spain, and Germany arrested nine suspects connected to a laundering network tied to $689 million (€600 million) in fraud.

  • Last month: Europol seized $330,000 in cryptocurrency and arrested seven individuals involved in a cybercrime-as-a-service network run out of Latvia.

Europol officials warn that criminal abuse of crypto is becoming more sophisticated, placing increasing pressure on the resources of EU law enforcement agencies.
