A Bulgarian national who was convicted by a federal jury for his role in a transnational and multimillion-dollar scheme to defraud American victims was sentenced today to 121 months in prison. U.S. District Court Judge Robert E. Weir sentenced Rossen G. Iossifov, 53, formerly of Bulgaria, for conspiracy to commit a Racketeer Influenced and Corrupt Organizations Act (RICO) offense and conspiracy to commit money laundering. According to trial evidence, Iossifov owned and managed RG Coins, a cryptocurrency exchange headquartered in Sofia, Bulgaria. According to the evidence at trial, Iossifov knowingly and intentionally engaged in business practices designed to both assist fraudsters in laundering the proceeds of their fraud and to shield himself from criminal liability. At least five of Iossifov’s principal clients in Bulgaria were Romanian scammers, who belonged to a criminal enterprise known in court records as the Alexandria (Romania) Online Auction Fraud (AOAF) Network. Evidence submitted during trial and his sentencing hearing revealed that Iossifov laundered nearly $5 million in cryptocurrency for four of these five scammers in a period of less than three years. This represented over $7 million in funds defrauded from American victims. In return, Iossifov made over $184,000 in proceeds from these transactions.
