The long-standing dispute between Star Xu, founder of the cryptocurrency exchange OKX, and Changpeng Zhao (CZ), founder of Binance, has resurfaced following the release of Zhao's memoir. Xu has accused Zhao of being a 'habitual liar' regarding a contract dispute from Zhao's time at OKCoin in 2015, where he faced allegations of misleading conduct. In his posts on X, Xu shared a video claiming to show conflicting versions of contracts and reiterated that Zhao misled the public. The feud has taken a personal turn, with Xu questioning Zhao's marital status and the implications of his divorce on his Binance stake. Zhao responded by asserting his official divorce status and challenged Xu to a $1 billion wager on the matter, which Xu declined, citing regulatory compliance concerns. This public spat highlights the ongoing tensions in the cryptocurrency industry and the personal animosities that can arise among its prominent figures.
