The crypto world is once again witnessing a public spat between two of its most prominent figures: OKX founder Star Xu and Binance's Changpeng "CZ" Zhao. This long-simmering rivalry has boiled over, with Xu leveling accusations of "habitual lying" against CZ, reigniting a decade-old contract dispute that traces back to Zhao's early days in the industry.
The Memoir's Spark: Reopening Old Wounds
The catalyst for this latest flare-up? The recent release of CZ's memoir. Xu claims the book forced him to revisit past issues, specifically a 2015 incident during CZ's brief stint at OKCoin, the exchange founded by Xu. According to Xu, he had "no intention of revisiting these old issues involving CZ [...] but since I’ve been dragged into this again because of the book, let’s restate the facts."
A Decade-Old Grievance: The OKCoin Contract Dispute
The core of the historical contention dates back to Zhao’s tenure at OKCoin, when he was accused in 2015 of "harmful acts of conduct" and misleading statements tied to a contract dispute involving early Bitcoin investor Roger Ver. Zhao has consistently disputed these claims. In his recent posts, Xu pointed to a video he says shows evidence of conflicting contract versions, reiterating his assertion that Zhao had misled the public about the matter. "After spending four months in prison, he continues to make false statements to the world," Xu wrote, adding that "a habitual liar never changes their nature."
Escalation to Personal Attacks: Divorce and Binance Stake
The dispute quickly veered into personal territory, moving beyond historical business disagreements. Xu questioned CZ's marital status, referencing earlier CoinDesk reporting in which Zhao’s spouse was described as his "wife" in a letter submitted to a judge. Xu publicly demanded proof of divorce, promising an apology if Zhao could produce a signed divorce agreement.
CZ's Counter: A Billion-Dollar Bet and Dismissal
CZ swiftly retorted, confirming he is "officially divorced" and challenging Xu to a substantial wager. He offered a $1 billion bet, or any amount Xu chose, on the finalization of his divorce, stating that lawyers could verify the agreement while declining to publish the documents publicly. Xu rejected the wager, citing compliance considerations tied to running a regulated exchange. Instead, he pressed CZ further, questioning whether his Binance stake had been legally separated as part of any divorce proceedings. Zhao dismissed this line of questioning, stating his Binance stake was "none of your business" and accusing Xu of deflection.
Why It Matters Now: Implications for the Crypto Community
This public spectacle between the founders of two of the world's largest crypto exchanges isn't just personal drama; it highlights the deep-seated rivalries and often-turbulent human element within the industry's highest echelons. For traders, investors, and the wider crypto community, such high-profile disputes, even if personal, can introduce an element of uncertainty. They serve as a stark reminder that even the most established platforms are ultimately steered by individuals, whose public conduct can influence market sentiment, trust, and the overall perception of leadership in a still-maturing industry. The ongoing animosity between these titans underscores the competitive and often contentious landscape of global cryptocurrency exchanges.
