Wintermute Trading Ltd., one of the biggest cryptocurrency market makers, was accused in a proposed class-action lawsuit of helping former Celsius Network Ltd. Chief Executive Officer Alex Mashinsky dupe investors in his now-bankrupt crypto lending firm, Bloomberg News reported. Plaintiffs who sued Mashinsky and other Celsius executives in July 2022 amended their federal lawsuit in New Jersey this week to add London-based Wintermute as a defendant, entangling another major industry player in the fallout from Celsius’s collapse. According to the lawsuit, Wintermute engaged in “wash trading” — which creates the illusion that an asset is trading far more often than it actually is — and other improper activities starting in March 2021 to inflate the value of Celsius’s native CEL token and loan products. Wintermute also played a key role in Mashinsky’s futile effort to prop up CEL in May 2022 after the collapse of the Terra and Luna tokens, the investors alleged. “This wash trading activity corrupted the CEL Token prices, as well as the reported trading volume, all in a strategic pattern to deceive investors,” lawyers for the investors said in the suit. Celsius froze all accounts on June 13, 2022, and filed for bankruptcy the next month amid a $2 trillion market crash that wiped out some of the industry’s biggest names and exposed hundreds of thousands of investors to steep losses.
