OKX CEO Star Xu publicly challenged claims by Binance founder Changpeng Zhao about selling a house to buy Bitcoin, raising questions about ownership and funding. Xu shared the remarks following the release of CZ’s book. He said the story omits key details and resurfaced older disputes tied to OKCoin.
Star Xu Questions CZ’s Bitcoin Purchase Story
Star Xu questioned CZ’s claim that he sold his apartment for $900,000 to buy Bitcoin at $400. He asked where the initial down payment came from and who owned the property. CZ has built a fortune out of crypto.
CZ from Binance said that when he first got into Bitcoin, he sold his apartment for $900K to buy the dip at $400.
Even though he didn’t even have a job at the time.

As Coingape reported, CZ is among some crypto leaders who were in the Forbes billionaire list for 2026. Additionally, Xu suggested the house may have belonged to CZ’s in-laws, not CZ himself. He also raised concerns about how the story has been repeatedly presented publicly.
According to Star Xu, in an X post, the narrative overlooks the role of family members who supported CZ during that period. He added that the portrayal may ignore the feelings of elderly in-laws.
Also, Xu said he avoided discussing these matters publicly in the past. However, he stated that a recently published book forced him to respond. He described the book as containing falsehoods about his own history. As a result, he revisited details he previously chose not to disclose.
Dispute Extends to Personal and Legal Claims
Star Xu also raised questions about CZ’s marital status, citing inconsistencies in public statements. He referenced reporting by a top media outlet, which included a letter submitted by CZ’s wife. In that letter, she reportedly referred to them as husband and wife.
However, the CEO of the top crypto exchange OKX said CZ has described their relationship differently in interviews and his book. He asked whether a divorce had occurred and, if so, whether assets were divided legally. Xu referenced examples involving Jeff Bezos and Bill Gates, who followed legal processes during their divorces.
Also, Xu stated he would issue a public apology if CZ provided a signed divorce agreement. Otherwise, he said claims of divorce would amount to public misrepresentation.
Old OKCoin Dispute Resurfaces
Star Xu also revisited a 2015 controversy involving a contract linked to early Bitcoin investor Roger Ver. At the time, allegations emerged about contract falsification during CZ’s tenure at OKCoin.
The Binance founder addressed the episode in his book, denying any wrongdoing. He described the conflict as a disagreement over leadership and vision rather than misconduct. However, Star Xu rejected that account and said previously published evidence still stands.
Star Xu referenced archived materials and a notarized video shared online years ago. He also recalled CZ’s earlier response, where CZ suggested his QQ account may have been accessed by another employee. Xu disputed that explanation and maintained the evidence remains unchanged.
