Federal prosecutors brought criminal charges against 10 individuals on March 30 who worked for four cryptocurrency market-making companies accused of artificially manipulating digital asset prices and creating false trading volume.
Those facing charges held positions ranging from employees to senior executives at Gotbit, Vortex, Antier, and Contrarian. Federal prosecutors allege these companies engaged in coordinated trading activities designed to fabricate the appearance of legitimate market activity.
Documents filed with the court describe a scheme where the same tokens were purchased and sold repeatedly through a technique called wash trading, which artificially drove up both reported trading volumes and token prices.
After successfully inflating prices, prosecutors claim the firms offloaded these tokens to retail investors who remained unaware of the underlying manipulation scheme.
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.”
Law enforcement conducted this investigation through Operation Token Mirrors. Federal agents went so far as to develop their own cryptocurrency called NexFundAI as part of the undercover operation.
Investigators used this fabricated token to engage with market-making companies and gather documentation showing how wash trading services were marketed and executed.
Indictments came down between March and September 2025. Singaporean law enforcement arrested defendants before three senior figures were extradited to face charges in American courts.
Extraditions and Plea Agreements
The three extradited defendants made their initial court appearances in federal court located in Oakland, California following their transfer from Singapore.
Two additional defendants entered guilty pleas prior to the extradition proceedings. U.S. District Court Judge Araceli Martínez-Olguín handed down sentences in those cases.
The FBI partnered with the IRS Criminal Investigation Division to execute this undercover operation. Both federal agencies have expanded their enforcement efforts targeting fraudulent cryptocurrency activities over the past several years.
Federal prosecutors emphasized that these pump-and-dump operations resulted in financial harm to investors across multiple countries.
Confiscated Cryptocurrency and Financial Harm
Documents submitted to the court verify that federal authorities have seized more than $1 million worth of cryptocurrency throughout 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 declined to reveal the complete extent of investor losses in public communications.
This prosecution stands as one of the most comprehensive undercover investigations focused on cryptocurrency market manipulation, with federal agents creating an entire token ecosystem to document criminal activity.
The three defendants brought from Singapore remain in federal custody awaiting trial proceedings in Oakland federal court.
