Today, the Dutch Fiscal Information and Investigation Service (FIOD), in close cooperation with Europol and the authorities in Luxembourg, clamped down on one of the world’s leading cryptocurrency mixing service Bestmixer.io.
Initiated back in June 2018 by the FIOD with the support of the internet security company McAfee, this investigation resulted in the seizure of six servers in the Netherlands and Luxembourg.
ONE OF THE LARGEST MIXING SERVICES
Bestmixer.io was one of the three largest mixing services for cryptocurrencies and offered services for mixing the cryptocurrencies bitcoins, bitcoin cash and litecoins. The service started in May 2018 and achieved a turnover of at least $200 million (approx. 27,000 bitcoins) in a year’s time and guaranteed that the customers would remain anonymous.
NATURE OF THE SERVICE
A cryptocurrency tumbler or cryptocurrency mixing service is a service offered to mix potentially identifiable or ‘tainted’ cryptocurrency funds with others, so as to obscure the trail back to the fund’s original source.
The investigation so far into this case has shown that many of the mixed cryptocurrencies on Bestmixer.io had a criminal origin or destination. In these cases, the mixer was probably used to conceal and launder criminal flows of money.
FOLLOW-UP
The Dutch FIOD has gathered information on all the interactions on this platform in the past year. This includes IP-addresses, transaction details, bitcoin addresses and chat messages. This information will now be analysed by the FIOD in cooperation with Europol and intelligence packages will be shared with other countries.
