Europol Shuts Down Notorious Cryptomixer, Seizes €25M in BTC and 12TB of Data
Europol, in collaboration with law enforcement authorities in Germany and Switzerland, has , one of Europe’s most well-known custodial BTC mixing services. The operation led to the seizure of €25 million, approximately $27 million, in BTC and the confiscation of more than 12 terabytes of user data linked to the platform’s activities.
The coordinated action took place in Zurich between November 24 and 28, with Europol providing continuous support throughout the week. During the operation, investigators seized three servers, took control of the Cryptomixer domain, and replaced the website with an official law enforcement seizure notice.
Authorities said the platform operated on both the clearnet and the dark web and had been active since 2016. Over that period, it processed more than €1.3 billion in BTC transactions. According to investigators, the service was widely used to launder funds tied to ransomware attacks, dark web marketplaces, fraud schemes, and other forms of organised cybercrime.
Cryptomixer’s software worked by pooling deposits over extended and randomised periods before redistributing the funds to newly generated addresses. This process was designed to break the traceability of transactions, making it hard for authorities to track the origin and destination of illicit funds. Law enforcement linked the platform to proceeds from drug trafficking, arms trafficking, payment card fraud, and cyberattacks.
Europol coordinated intelligence-sharing efforts through its Joint Cybercrime Action Taskforce and deployed forensic specialists to support the operation. The agency noted that the takedown follows previous actions against similar services, including the dismantling of ChipMixer in 2023, which was then considered the largest cryptomixer in operation.
Europol Steps Up Global Pressure on Crypto Laundering and Dark‑Web Finance Infrastructure
Europol, in coordination with European and international law enforcement, has . The agency’s actions span multiple high-profile cases.
A similar crackdown occurred years back. In 2019, Bestmixer.io was among the largest crypto mixers worldwide; its shutdown involved the seizure of six servers .
In mid‑2025, a coordinated operation led to arrests across Spain and the Canary Islands tied to a network that reportedly laundered some €460 million via shell companies, crypto platforms, and payment gateways before investigators intervened.
Then, more recently in September 2025, Canadian police, acting on a lead from Europol, — described as the largest crypto seizure in Canadian history — later than concluding the platform had operated without a license and facilitated criminal fund flows.
