A long-standing rivalry between two powerful men in the crypto world, Star Xu, and Changpeng Zhao, founder of the rival exchange OKX, has escalated into a billion dollar showdown after Zhao's autobiography, 'Freedom of Money', released. Zhao claimed that Huobi founder Li Lin had told him in 2025 that he had been arrested due to a whistleblower report linked to Xu, but Xu denied this, calling it a lie and stating he never reported Li to the authorities. Xu accused Zhao of spreading "purely false information" and challenging his personal and professional integrity. Zhao responded by offering to bet $1 billion that he was officially divorced long before today, but declined to publicly disclose this bet. The dispute stemmed from a dispute when Zhao was a senior executive at OKCoin, the predecessor to OKX.
