Three executives from cryptocurrency market-making firms have been extradited to the United States and appeared in federal court, marking a significant development in a growing case of alleged crypto wash trading. The US Department of Justice (DOJ) has charged a total of 10 foreign nationals connected to four companies: Gotbit, Vortex, Antier, and Contrarian.

Expanding Crackdown on Market Manipulation

The case centers around schemes designed to artificially inflate the prices and trading volumes of digital assets. Prosecutors allege that these actions created a false impression of liquidity and demand in the market.

Timeline of Charges

  • October 2024: Initial charges were unsealed, launching an international enforcement effort.
  • March 2025: Charges were filed related to Gotbit.
  • August 2025: A case involving Vortex was brought forward.
  • September 2025: Charges were filed against Contrarian and Antier.
  • October 2025: Vortex CEO Gleb Gora, Contrarian CEO Manu Singh, and Contrarian employee Vasu Sharma were arrested in Singapore and subsequently extradited.

Alleged Tactics and Charges

According to indictments, the defendants employed tactics such as wash trading, matched orders, and prearranged transactions to generate artificial trading volume. These actions were allegedly intended to support token prices and mislead investors.

The schemes targeted various tokens, including NexFundAI, a token created by the FBI to expose fraudulent market-making practices. One entity involved agreed to pay a $428,059 fine, forfeit funds, and accept a US trading ban as part of a settlement with prosecutors and the Securities and Exchange Commission (SEC).

Ongoing Investigation

The DOJ describes the operation as targeting “market-manipulation-as-a-service,” indicating a broader effort to address fraudulent practices within the cryptocurrency industry. The investigation, dating back to 2018, continues to unfold as authorities pursue those allegedly involved in these schemes.
