US law enforcement continues to make no secret of their efforts to work closely with experts and overseas partners to prosecute those involved in virtual currency transactions who attempt to rely on its purported anonymity to commit financial crimes. Tuesday’s arrest of Roman Sterlingov, a dual citizen of Russia and Sweden and alleged operator of Bitcoin Fog, in Los Angeles is a clear case that these efforts are paying dividends. In a criminal complaint filed by the US Attorney’s Office for the District of Columbia, Sterlingov is accused of laundering hundreds of millions of dollars’ worth of bitcoin. According to a statement of facts accompanying the complaint filed in the District of Columbia, Sterlingov was allegedly running “an illicit bitcoin money transmitting and money laundering service.” (Case 1:21-mj-00400-RMM Document 1-1 Filed 04/26/21.) Notably, investigators from the Internal Revenue Service (IRS) and Federal Bureau of Investigation (FBI) were able to obtain records of Sterlingov’s True Name accounts at several cryptocurrency exchanges. Investigators also analyzed bitcoin transactions, email records, financial records and internet service provider records. The investigation and arrest come at a time when the IRS, together with other enforcement agencies, are taking a hard look at cryptocurrency activity and have recently issued John Doe summonses to two virtual currency exchanges.

The collaboration with private experts and international partners is clear from the press release issued by the US Department of Justice (DOJ). In recognizing the many agencies that assisted in the investigation, the DOJ specifically stated that essential support was provided by Excygent, which is described on its website “as a highly specialized, professional services firm that assists organizations in both the public and private sectors with cybercrime investigative and analysis capabilities.” The DOJ also listed several US agencies that provided invaluable assistance and went on to include international partners: Europol, the Swedish Economic Crime Authority, the Swedish Prosecution Authority, the Swedish Police and the General Inspectorate of Romanian Police, Directorate for Combatting Organized Crime and the Directorate for Investigating Organized Crime and Terrorism. This ability to collaborate successfully will most likely serve as a blueprint for future investigations.

Practice Point: As we noted in our blog post, “Finding John Doe: IRS Steps up Enforcement Efforts to Take the Anonymity Out of Virtual Currency,” the time is now for those who have engaged in a virtual currency transaction to assess any potential tax and criminal implications, and businesses in this industry should carefully review their policies and processes to ensure that they address potential tax avoidance and anti-money laundering risks associated with their operations. The IRS is working closely with its new partners (i.e., industry experts and foreign law enforcement) to address any noncompliance. As announced recently by US President Joe Biden, he plans to give them the resources to do more on enforcement.
