Three cryptocurrency executives extradited from Singapore appeared in federal court in Oakland as US prosecutors expanded a major crypto wash trading case involving 10 foreign nationals linked to four market-maker firms: Gotbit, Vortex, Antier, and Contrarian.
The US Department of Justice (DOJ) said the charges stem from alleged schemes dating back to 2018, where coordinated trading activity was used to inflate token prices and trading volumes, making assets appear more liquid and in higher demand than they actually were.

Multi-Year Crackdown Targets Market Manipulation
The current case builds on an undercover operation first unsealed in October 2024, when US authorities charged 18 individuals and entities in a global crackdown on crypto investment fraud and manipulation.
According to the DOJ, Gotbit-related charges were filed in March 2025, followed by Vortex in August 2025, and Contrarian-Antier cases in September 2025. Authorities reported that Vortex CEO Gleb Gora, Contrarian CEO Manu Singh, and employee Vasu Sharma were arrested in Singapore in October 2025 before being extradited to the United States.
Wash Trading Methods and Related Guilty Pleas
Indictments describe tactics such as wash trading, matched orders, and prearranged transactions designed to create artificial trading volume before insiders sold tokens.
In related actions, Gotbit agreed to cease operations and forfeit about $23 million in seized cryptocurrency. In another case, UAE-based CLS Global pleaded guilty in Massachusetts to manipulating trading of NexFundAI (NEXF), an FBI-created token, agreeing to pay a $428,059 fine, forfeit funds, and accept a US trading ban.
