U.S. Charges 10 Foreign Nationals Over Alleged Crypto Wash-Trading and Pump-and-Dump Scheme
U.S. authorities have charged 10 foreign nationals in a sweeping enforcement action targeting alleged crypto market manipulation tied to several market-making firms.
The U.S. Department of Justice said the defendants used wash trading and pump-and-dump tactics to manufacture trading activity, boost token prices and volume, then sell into the rally at higher levels. The operation also led to arrests, guilty pleas and the seizure of more than $1 million in digital assets.
Executives and employees linked to four firms—Gotbit, Vortex, Antier and Contrarian—were indicted on March 30 by federal grand juries on fraud and conspiracy allegations. Prosecutors allege the group created fake market activity and sold tokens at inflated prices, harming investors worldwide. The DOJ said the defendants operated as illicit market makers, using wash trades to artificially inflate reported trading volume.
Three defendants, including two CEOs, were arrested in Singapore and later extradited to the United States. Two others have already pleaded guilty, while several remain under indictment. If convicted, each defendant could face up to 20 years in prison and fines of up to $250,000 per charge.
Court filings outline a multi-part series of indictments in 2025. On March 25, 2025, three individuals tied to Gotbit were charged with wire-fraud conspiracy related to token price manipulation. On Aug. 28, 2025, Vortex executives—including CEO Gleb Gora, 24, and CFO Sergei Ryzhkov—were charged in a similar case. On Sept. 4, 2025, four individuals associated with Contrarian and Antier were indicted for allegedly planning token price pumps. Several defendants were arrested in Singapore on Oct. 2, 2025, and later appeared in federal court in Oakland.
The investigation followed an undercover operation led by the FBI and IRS Criminal Investigation. Authorities said investigators created multiple test tokens to identify manipulation methods, alleging the defendants repeatedly inflated trading volume to draw in buyers before selling their positions at elevated prices.
Regulators have intensified scrutiny of market makers and liquidity providers accused of creating artificial demand across crypto markets, and the DOJ framed the latest case as part of that broader crackdown.
