U.S. federal prosecutors have charged ten executives and employees from four cryptocurrency market-making firms in connection with alleged fraud schemes designed to manipulate digital asset prices and trading volumes.
The indictments, returned by federal grand juries in California, target individuals linked to Gotbit, Vortex, Antier Solutions Private Limited, and Contrarian.
Authorities allege the defendants engaged in coordinated “wash trading” to artificially inflate the value and activity of certain cryptocurrencies before selling them at elevated prices to unsuspecting investors.
According to prosecutors, these pump-and-dump schemes generated illicit profits while causing financial losses to investors in the United States and abroad.
Wash trading involves executing trades in which the same parties act as both buyers and sellers, creating a misleading appearance of market demand and liquidity.
The investigation was led by the Federal Bureau of Investigation and IRS Criminal Investigation, which conducted an undercover operation that included the creation of digital tokens to expose fraudulent practices in the crypto market.
Three defendants, including senior executives, were arrested in Singapore and extradited to the United States, where they made their initial court appearances in Oakland, California.
Among them are executives tied to Vortex and Contrarian. Several others have already faced legal consequences, with two individuals pleading guilty and receiving sentences in federal court.
Authorities have seized more than $1 million in cryptocurrency linked to the schemes so far. Prosecutors said the defendants face charges of wire fraud and conspiracy, each carrying potential penalties of up to 20 years in prison and significant financial fines if convicted.
U.S. officials emphasized that the case highlights growing enforcement efforts against market manipulation in the cryptocurrency sector.
The crackdown also underscores the increasing use of international cooperation, with assistance from Singaporean authorities enabling arrests and extraditions.
The cases remain ongoing, and all defendants are presumed innocent unless proven guilty in court. The prosecutions signal a broader push by regulators to address fraudulent practices and improve transparency in digital asset markets.
