Crypto Exchange CEOs Fight: OKX's Xu Calls Binance's CZ a 'Liar'

The leaders of two of the world's biggest cryptocurrency exchanges are in a heated public argument on social media.

Star Xu, who founded OKX (a major crypto exchange where people buy and sell digital currencies), called Changpeng Zhao (known as "CZ"), the founder of Binance (the world's largest crypto exchange), a "habitual liar" on X (formerly Twitter).

This fight isn't new. It goes back to 2015 when CZ briefly worked at Xu's first company, OKCoin. Back then, there was a messy dispute about contracts and business dealings. CZ was accused of misleading people and harmful behavior, which he denied.

The argument heated up again this week after CZ published his memoir (a book about his life). This prompted Xu to bring up the old accusations again, even sharing videos he claims prove CZ lied about their past business dealings.

Key points of their dispute: • Xu questions CZ's honesty about old business contracts • The fight has gotten personal, with Xu asking about CZ's divorce and ownership of Binance • CZ responded that he is officially divorced and called Xu's questions irrelevant • In January, Xu also blamed Binance for causing a cryptocurrency market crash

This public feud shows how personal rivalries can affect the cryptocurrency industry. Both men run exchanges that handle billions of dollars in digital currency trades daily, making their conflict significant for the crypto world.
