The U.S. Department of Justice has charged market makers and employees over alleged artificial inflation of cryptocurrency prices and trading volumes.

Case overview

The case involves firms Gotbit, Vortex, Antier and Contrarian, with 10 individuals accused in related federal filings.

Allegations

Prosecutors say the defendants engaged in wash trades, executing phony buy and sell orders to create artificial demand and inflate token prices.

According to the indictment, operators later sold those assets to outside investors at elevated prices, generating misleading market signals.

Reported tactics

• Executing self-directed trades to simulate volume and sustain higher quoted token prices.
• Coordinating order flows among affiliated accounts to create the appearance of genuine demand.
• Converting artificially supported prices into sales to external investors at inflated values.

Extraditions and enforcement

Three defendants have been extradited from Singapore to the United States, and related proceedings are currently active in federal court.

The Department of Justice has filed charges alleging manipulation within digital-asset markets and continues to update court filings as the investigation proceeds.

Undercover element

As part of investigative efforts, agents from the FBI and IRS reportedly issued tokens to trace trading activity and collect evidence of coordinated misconduct.

Authorities say that operation helped uncover coordination among market-makers and intermediaries that created misleading volume and price signals.
