Chinese poker master and crypto investor Hu Zhewen is pursuing lawsuits against Jump Trading and Rutgers University professor Zhang Yongfeng after losses across three consecutive crypto market cycles. Hu is seeking at least $500 million in damages from Jump Trading and affiliated entities in a Chicago court. Between May 2021 and May 2022, he invested about $80 million in TerraUSD (UST) and LUNA; the holdings later exceeded $800 million in value before the tokens fell to near zero. Hu also sued Zhang for securities fraud after investing millions of dollars in tokens issued by Zhang’s institution, which have declined more than 99.6% from their 2025 peak. Earlier, Hu said an investment in Stratis generated returns exceeding 1,000 times, but later bets on algorithmic stablecoins and AI tokens produced substantial losses.
