The Golden State Warriors were sued on Monday by an FTX customer who accused the reigning National Basketball Association champions of fraudulently promoting the now-bankrupt cryptocurrency exchange. Elliott Lam, a Canadian citizen and Hong Kong resident, filed his proposed class-action lawsuit in San Francisco federal court on behalf of "thousands, if not millions" of people outside the United States who traded on FTX's platform. Other defendants include Sam Bankman-Fried, who founded FTX, and Caroline Ellison, who led Bankman-Fried's trading firm Alameda Research.
