CZ and Xu Star relive decade-old dispute on X with accusations and $1 billion bet

A long-running dispute between OKX founder Star Xu and Binance founder Changpeng “CZ” Zhao resurfaced Thursday, with Xu calling CZ a “habitual liar” in a series of posts on X that revisit allegations dating back more than a decade.

The clash traces back to Zhao’s brief tenure at OKCoin, founded by Xu, when he was accused in 2015 of “harmful acts of conduct” and misleading statements tied to a contract dispute involving Roger Ver, claims Zhao has previously disputed.

This latest flare-up also follows an earlier public disagreement in January, when Xu blamed Binance-linked market dynamics for amplifying the Oct. 10 crypto crash, a claim Binance and other market participants disputed. The latest flare-up was triggered by CZ’s memoir, published earlier this week, Xu said.

He revived the decade-old issues, saying 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,” he wrote.

“Out of the blue, Star [Xu] said that I had somehow forged a contract when working there [at OKCoin],” CZ said in his book. “… In May 2015, I got annoyed and made a public post on Reddit, obviously denying forging any contracts … while I was at it, I detailed a few problems I saw at OKCoin.”

Xu, in his recent posts, pointed to a video he said shows evidence of conflicting contract versions and reiterating 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.”

The dispute escalated when Xu questioned whether Zhao had misrepresented his marital status, referencing earlier CoinDesk reporting in which Zhao’s spouse was described as his “wife” in a letter submitted to a judge. Xu said he would apologize if Zhao could produce a divorce agreement signed by both parties.

Zhao responded that he is “officially divorced” and challenged Xu to a $1 billion bet or any amount Xu chose, that the divorce had been finalized, saying lawyers could verify the agreement while declining to publish documents.

Xu rejected the wager, citing compliance considerations tied to running a regulated exchange, and instead pressed Zhao on whether his Binance stake had been legally separated as part of any divorce.

Zhao dismissed the line of questioning, saying his Binance stake was “none of your business” and accused Xu of deflecting.

Federal judge blocks Arizona from bringing criminal charges against Kalshi

Federal judge blocks Arizona from bringing criminal charges against Kalshi

A federal judge has blocked the state of Arizona from bringing criminal charges against prediction market provider Kalshi, at least temporarily, in response to a motion from the Commodity Futures Trading Commission.

District Judge Michael Liburdi, in the District of Arizona, ruled Friday that Arizona cannot hold an arraignment of Kalshi as scheduled on Monday, April 13. Arizona announced last month it would file 20 criminal charges against Kalshi for offering what the state claimed were betting products in violation of Arizona law.

“Defendants are temporarily restrained and enjoined from enforcing AZ’s gambling laws in any criminal or civil enforcement actions to any contracts listed on CFTC-regulated [designated contract markets],” the judge ruled in the temporary restraining order, according to Paradigm senior regulatory counsel Stefan Schropp.

In a statement Friday, CFTC Chair Michael Selig said the regulator “appreciated” the judge’s decision.

“Arizona’s decision to weaponize state criminal law against companies that comply with federal law sets a dangerous precedent, and the court’s order today sends a clear message that intimidation is not an acceptable tactic to circumvent federal law,” he said.

The CFTC sued Arizona and two other states arguing that prediction markets, otherwise known as event contracts, are swaps subject to the federal agency’s supervision, and that its role preempts state law.

It’s a view that’s seen largely mixed results in court; state courts have often sided with states, such as when a Nevada state court ruled that the Gaming Control Board could temporarily block Kalshi while a broader case moves forward.

Federal courts have had different results; the Third Circuit Court of Appeals ruled earlier this week that prediction markets are subject to CFTC rule, and it was up to the CFTC’s discretion on if it wanted to block providers from offering sports-related products or not.

The Ninth Circuit Court of Appeals declined to weigh in on the aforementioned Nevada action, allowing that state court to block Kalshi, but it will hold a hearing on a consolidated case next week allowing various providers and other parties to argue.

Judge Liburdi of Arizona granted the CFTC’s motion to block the Arizona state action against Kalshi two days after denying Kalshi’s own motion for a preliminary injunction against the state.

Bitcoin Community Weighs Reports of Hormuz Oil Tanker Fees Payable in BTC

Published

Dollar, Iran, Stablecoin, Bitcoin Adoption

The Bitcoin (BTC) community is discussing the feasibility and implications of the Iranian government accepting BTC for tolls paid by oil tankers crossing the Strait of Hormuz, a critical shipping lane through which about 20% of the global oil supply passes. 

The reactions were sparked by a Financial Times report, published on Wednesday, which said that the Iranian government was considering BTC payments for oil tolls to avoid sanctions imposed by the United States.

Several conflicting reports have been published since the Financial Times article, which suggest that the tolls are payable in stablecoins or Chinese yuan, according to Alex Thorn, the head of firmwide research at crypto investment firm Galaxy.

BTC advocate Justin Bechler said that stablecoins can be frozen by the issuer and cited the compliance controls introduced in the GENIUS stablecoin regulatory framework as reasons why the Iranian government would not collect tolls in US-dollar stablecoins. He said:

“USDT and USDC include built-in blacklist functions at the smart contract level. When an address is flagged, the issuer can freeze the tokens, rendering them completely illiquid. The law’s enforcement depends entirely on the compliance of issuers.

Bitcoin has no issuer, no compliance officer to pressure, and no freeze function. Iran’s pivot toward Bitcoin follows directly from this structural reality,” he added.

If the Iranian government begins accepting BTC for oil tanker payments, it would boost Bitcoin’s credibility as a neutral settlement layer for international transactions, advocates say.

Iran would likely use QR codes to collect BTC payments

Thorn estimated that each oil tanker would need to pay between $200,000 and $2 million in tolls to pass through the Strait of Hormuz.

The initial reporting from the Financial Times cited a spokesperson for Iran’s Oil, Gas and Petrochemical Products Exporters’ Union, who said that ships would have a “few seconds” to complete payment in BTC.

This suggests that ships would pay via the Lightning Network, a layer-2 payment solution for BTC that allows parties to send transactions in seconds, rather than waiting for the 10-minute block confirmation.

However, the largest known transaction over the Lightning network to date has been for $1 million, Thorn said. 

“More likely, the Iranian authorities would provide a QR code or alphanumeric Bitcoin address to the ships upon approval of their requests to pass through the Strait,” he added.
