FBI Unmasks Alleged Crypto Price-Manipulation Ring; 10 Foreign Nationals Charged

U.S. authorities have widened their crackdown on alleged crypto market abuse, underscoring growing enforcement risk for digital-asset firms that provide coordinated trading designed to boost token prices and volumes. The Department of Justice said March 30 it filed charges against 10 individuals connected to four firms—Gotbit, Vortex, Antier and Contrarian—accused of running structured trading programs intended to simulate demand, inflate valuations and mislead investors. "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," officials said. Investigators said the activity spanned multiple jurisdictions. Three defendants, including senior executives, were extradited from Singapore and appeared in federal court in Oakland. Prosecutors added that two other defendants had already pleaded guilty and were sentenced by U.S. District Judge Araceli Martínez-Olguín. The investigation, dubbed Operation Token Mirrors, relied on an FBI-created token—NexFundAI—used in an undercover effort to engage market-making providers and document how wash-trading services were marketed and carried out. Court filings show indictments were issued between March and September 2025, followed by arrests in Singapore and extraditions that brought key executives into U.S. custody. Prosecutors described the alleged conduct as classic pump-and-dump behavior: inflating token metrics before selling into the market. "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," they said.
