Key Takeaways:
(P1) The U.S. Department of Justice charged 10 executives from four international crypto market-making firms with orchestrating pump-and-dump schemes, culminating in the extradition of three individuals from Singapore to a federal court in Oakland.
(P2) "These so-called pump-and-dump schemes caused losses to investors in the United States and elsewhere," prosecutors from the U.S. Attorney's Office for the Northern District of California said in a statement, noting that authorities have seized more than $1 million in cryptocurrency assets to date.
(P3) The indictments name employees and executives from Gotbit, Vortex, Antier, and Contrarian, who are accused of using wash trading to artificially inflate the price and trading volume of various cryptocurrencies. The charges, including wire fraud and conspiracy, stem from a multi-year investigation that utilized an undercover FBI operation involving a bureau-created token to expose the alleged manipulation services.
(P4) The case highlights a significant expansion of U.S. enforcement reach, targeting foreign nationals operating outside the country whose actions allegedly impact U.S. investors. The collaboration with Singaporean authorities for the arrests and extraditions signals a growing international focus on crypto market integrity. If convicted, defendants face up to 20 years in prison and fines of up to $250,000 for each violation.
According to the Justice Department, the core of the investigation involved an undercover operation where the FBI created its own cryptocurrency tokens. Investigators then engaged with the defendant firms, who allegedly offered "market-manipulation-as-a-service."
The firms are accused of employing wash trading—placing simultaneous buy and sell orders for the same asset—to create the false appearance of organic trading volume and demand. This tactic was designed to lure unsuspecting investors into buying the tokens at inflated prices, allowing the firms and their clients to sell their holdings for a profit.
The most recent development saw three defendants—Vortex CEO Gleb Gora, Contrarian CEO Manu Singh, and Contrarian employee Vasu Sharma—arrested in Singapore in October 2025 and extradited to the United States. They made their initial appearance in a federal court in Oakland, California, on March 30.
The Justice Department acknowledged the "valuable assistance" provided by the Singapore Police Force and the Attorney-General’s Chambers in securing the arrests. This international cooperation is a key feature of the broader U.S. crackdown on crypto-related crime, which has also involved actions against privacy tool developers and other illicit financial networks. Two other defendants in the case have already pleaded guilty and been sentenced.
