On March 30, the United States Department of Justice announced criminal charges against 10 individuals linked to four cryptocurrency market-making companies allegedly involved in systematically manipulating digital asset valuations and trading volumes.
The accused individuals hold various positions at Gotbit, Vortex, Antier, and Contrarian. Federal authorities claim these organizations engaged in orchestrated trading activities to fabricate the impression of genuine market interest.
Per legal documents submitted to the court, the purported conspiracy entailed repeatedly purchasing and selling identical digital tokens — a fraudulent tactic referred to as wash trading — with the intention of artificially elevating reported transaction volumes and asset prices.
Following the artificial price inflation, federal prosecutors contend the companies offloaded these digital assets to unsuspecting retail investors who remained unaware of the underlying market manipulation.
According to prosecutors: “The indictments allege that the defendants not only conspired to inflate the trading volume and price of cryptocurrencies but also profited through the sale of the cryptocurrencies at inflated prices to unwitting investors.”
The probe was executed through an initiative designated Operation Token Mirrors. During this operation, undercover FBI personnel developed a digital currency branded as NexFundAI.
Federal operatives deployed this fabricated token to engage with market-making organizations and compile evidence demonstrating how wash trading arrangements were proposed and executed.
The legal proceedings advanced through indictments filed between March and September 2025. Law enforcement actions in Singapore preceded the extradition of three high-ranking suspects to American soil.
Cross-Border Apprehensions and Plea Agreements
The three extradited individuals made their initial appearances before a federal magistrate in Oakland, California following their transfer from Singapore.
Two separate defendants had previously entered guilty pleas prior to the extradition proceedings. U.S. District Court Judge Araceli Martínez-Olguín handed down their sentences.
The Federal Bureau of Investigation partnered with the Internal Revenue Service Criminal Investigation Division to execute the undercover initiative. Both federal agencies have substantially expanded their enforcement efforts targeting cryptocurrency-related fraud schemes in recent years.
Federal prosecutors indicated that these pump-and-dump operations resulted in financial harm to investors across multiple jurisdictions, including domestic and international victims.
Confiscated Holdings and Victim Impact
Judicial filings verify that federal authorities have seized cryptocurrency holdings exceeding $1 million throughout the course of the ongoing investigation.
Prosecutors noted: “These so-called pump-and-dump schemes caused losses to investors in the United States and elsewhere … More than $1 million in cryptocurrency has been seized to date.”
The Department of Justice has not disclosed the aggregate financial losses sustained by investors in its public announcements.
This prosecution exemplifies one of the most comprehensive undercover investigations targeting cryptocurrency market manipulation tactics, with federal agents establishing an entirely fictitious digital asset to compile incriminating evidence.
The three extradited suspects remain in federal detention and are scheduled to proceed to trial in the Oakland federal courthouse.
