post-title

Law enforcement officers in the United States have arrested a man on suspicion of laundering hundreds of millions of dollars worth of Bitcoin (BTC) through a cryptocurrency mixing service.

A crypto-mixing service—also known as a cryptocurrency tumbler—obscures the original source of potentially identifiable or "tainted" cryptocurrency by jumbling it up with other funds in a single pool. 

An arrest warrant for Roman Sterlingov was successfully executed in Los Angeles, California, on April 27 and filed in the United States District Court for the District of Columbia on the same day.

The warrant accuses dual Russian and Swedish citizen Sterlingov of unlicensed money transmission, money laundering, and transmitting money without a license. 

Sterling was arrested by a special agent to the Internal Revenue Service Devon Beckett, who had been tasked with investigating the Bitcoin Fog darknet money-laundering service allegedly operated by Sterling.

In an affidavit, Beckett describes how Bitcoin Fog's administrator publicly advertised the organization's cryptocurrency mixer service "as a way to help users obfuscate the source of their Bitcoin" on a Twitter page and through a clearnet site.

Using blockchain analysis, law enforcement confirmed that over 1.2 million BTC valued at approximately $335,809.383 has been sent through the Bitcoin Fog site since it was established in October 2011. 

IRS-CI cyber-analysts determined that Bitcoin Fog received approximately 486,861.69 BTC valued at the time as approximately $54,897,316.44 directly from darknet markets.  

"Historically, the largest senders of BTC though Bitcoin Fog has been darkness markets, such as Agora, Silk Road 2.0, Silk Road, Evolution, and AlphaBay, that primarily trafficked in illegal narcotics and other illegal goods," wrote Beckett. 

Through an undercover transaction performed in September 2019 plus some analysis, an IRS special agent was able to determine that the crypto-tumbling service offered by Bitcoin Fog worked effectively to break the link in the blockchain between the source and ultimate destination of funds sent.

A second undercover transaction carried out in November 2019 revealed that Bitcoin Fog released funds to a user after being informed by that user that the money was the proceeds of illegal drug sales.

Beckett wrote that analysis of Bitcoin transactions, financial records, internet service provider records, email records, and additional investigative information identified Sterlingov as the principal operator of Bitcoin Fog.
