According to documents from the U.S. District Court for the Southern District of New York, a New York federal judge has granted class certification to the plaintiffs in a market manipulation lawsuit against Tether and Bitfinex, dividing the case into two groups of plaintiffs: spot investors and futures traders. The case reportedly alleges that Tether and Bitfinex manipulated cryptocurrency market prices between 2017 and 2019 by issuing USDT, causing investors who purchased BTC and ETH to lose hundreds of billions of dollars.
