ChipMixer, an unlicensed cryptocurrency mixer, was taken down by German and US authoritieson 15 March 2023, with help from Europol, Belgium, Poland, and Switzerland. The platform, which was set up in 2017, specialised in mixing/cutting trails related to virtual currency assets, making it attractive for money laundering activities.

Until its take-down, the platform had laundered an estimated 152.000 Bitcoins in crypto assets, worth roughly €2.73 billion according to current estimations. The platform was also used by ransomware actors to launder their ransom payments. On the action day, four servers, approximately 1909.4 Bitcoins (worth approx. €44.2 million), and 7 TB of data were seized.
