If crypto needed a reality show, the latest chapter in the decade-long rivalry between OKX founder Star Xu and Binance founder Changpeng “CZ” Zhao would easily make the season finale.
After CZ recently suggested that Xu’s repeated criticism stemmed from jealousy, the OKX founder wasted little time responding.
“I’m not jealous of him. I’m ashamed of him,” Xu wrote on X, before listing what he described as Binance’s past compliance failures, CZ’s prison sentence, market controversies, and allegations surrounding his time at OKCoin.
The exchange marks another escalation in one of crypto’s oldest founder rivalries—one that predates Binance itself.
A feud older than Binance
Before founding Binance in 2017, CZ briefly served as CTO at OKCoin, the predecessor to today’s OKX.
His departure from the company in 2015 led to years of public disagreements over contracts, company governance, and competing accounts of what happened behind the scenes.
The dispute resurfaced earlier this year after the release of CZ’s memoir, Freedom of Money, which revisited his departure from OKCoin and made fresh claims about Star Xu and other early crypto figures. Xu rejected the book’s account, accusing CZ of repeating falsehoods and misrepresenting past events.
Now, following Binance’s recent regulatory challenges in Europe, the war of words has resumed.
From “jealous” to “ashamed”
Xu’s latest post was unusually direct.
He questioned why anyone would be jealous of a founder who had served prison time, referenced Binance’s anti-money laundering settlement in the United States, criticized what he described as past compliance failures, and challenged CZ to publicly revisit historical disputes “with evidence” if necessary.
The remarks also referenced allegations concerning events during CZ’s time at OKCoin and claims made in his memoir. Those allegations remain disputed, with each founder maintaining sharply different versions of the events.
CZ has previously rejected similar accusations and has argued that Binance significantly strengthened its compliance program following regulatory actions in multiple jurisdictions.

The bigger story isn’t the insults
Behind the social media drama lies a more consequential battle.
Five years ago, major exchanges competed on:
- Trading volumes
- Token listings
- User growth
Today, the competition increasingly revolves around:
- Regulatory approvals
- Compliance culture
- Institutional credibility
- Global licensing
- Corporate governance
That shift has become even more apparent after Europe’s Markets in Crypto-Assets (MiCA) framework forced exchanges to compete on regulatory readiness rather than marketing alone.
Recent scrutiny over Binance’s European licensing efforts has only intensified that conversation, with rivals positioning compliance as a competitive advantage rather than merely a legal requirement.
Why it matters
Founder disputes are nothing new in crypto.
But this latest clash illustrates how the industry’s priorities have changed.
Where previous bull markets rewarded rapid expansion and aggressive growth, today’s environment increasingly rewards transparency, governance, and regulatory trust.
For exchanges seeking institutional adoption, reputation may now be just as valuable as trading volume.
The public feud between Star Xu and CZ may entertain crypto Twitter—but it also reflects a broader industry transition from “move fast and break things” to “prove you’re trustworthy.”
Whether either founder changes public opinion remains to be seen.
One thing is certain: crypto’s longest-running rivalry isn’t ending anytime soon.
