Authorities across Europe have shut down Cryptomixer, a cryptocurrency-mixing service used by cybercriminals to launder Bitcoin, seizing millions in crypto, critical servers, and terabytes of data.
Between November 24 and 28, 2025, law enforcement agencies from Switzerland and Germany, coordinated by Europol, reportedly targeted Cryptomixer, a crypto-mixing service alleged to have laundered over €1.3 billion ($1.51 billion) in Bitcoin since 2016.
According to Europol, authorities confiscated three servers, the platform’s domain, more than €25 million ($29 million) in BTC, and over 12 terabytes of operational data.
Europol Leads Cross-Border Raid
Europol’s cybercrime experts coordinated the operation, provided forensic support, and facilitated real-time information exchange among participating agencies. Following the takedown, a seizure banner was placed on the Cryptomixer website.
Cryptomixer was reportedly a hybrid mixing service accessible via both the clear web and the dark web. It allowed users to deposit Bitcoin, which was then pooled, randomized, and redistributed to destination addresses over extended periods.

The service was widely used by ransomware groups, dark web marketplaces, and other criminal networks to obscure the origin of illicit funds, including proceeds from drug trafficking, weapons sales, ransomware attacks, and payment-card fraud.
The raid involved Germany’s Federal Criminal Police Office and the Prosecutor General’s Cyber Crime Centre, as well as Zurich City Police, Zurich Cantonal Police, and the Public Prosecutor’s Office in Switzerland. Eurojust provided legal coordination and operational support.
Coordination Across Borders
Europol facilitated the exchange of intelligence through its Joint Cybercrime Action Taskforce (J-CAT), helping member states share expertise and conduct a coordinated takedown.
The Cryptomixer shutdown follows Europol’s 2023 dismantling of ChipMixer, then the largest crypto-mixing service. Authorities continue to prioritize tracing illicit cryptocurrency flows and targeting platforms that facilitate money laundering.
While crypto mixers claim to offer privacy, law enforcement agencies see them as tools for laundering proceeds of crime. The closure of Cryptomixer sends a clear message that regulators and police are intensifying efforts to disrupt illicit crypto networks and recover criminal assets.
