Bitcoin Mixer Tied to €1.3 Billion in Illicit Flows Taken Down by European Authorities

Authorities across Europe have shut down a crypto-mixing service “Cryptomixer,” allegedly used by cybercriminals to launder Bitcoin. They seized millions in crypto, critical servers, and terabytes of data.

Law enforcement agencies from Switzerland and Germany, coordinated by Europol, targeted Cryptomixer between November 24 and 28, 2025. It is 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.

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, which was then the largest crypto-mixing service.

In a similar crackdown, a Europe-wide enforcement effort recently traced more than €47 million in cryptocurrency moving through accounts linked to illegal streaming and digital piracy networks. Authorities said the findings mark one of the largest financial-tracking exercises ever conducted against online intellectual property crime.

Around the same time, another large-scale operation took down more than 1,400 fraudulent online trading platforms targeting retail investors. According to Reuters, German investigators, together with BaFin, Europol and Bulgarian authorities, traced networks of fake brokers that persuaded users to invest significant amounts with promises of high returns.
