Disgraced FTX founder Sam Bankman-Fried (SBF), currently serving time in federal prison, has sparked fresh controversy after implying that blockchain investigator ZachXBT might actually be Changpeng Zhao (CZ), the former CEO of Binance.
The comment has ignited fierce debate online, with the community divided over whether it was a miscommunication, a sarcastic remark, or something rooted in truth.

The wild claim emerged during a series of tense exchanges on X, where ZachXBT questioned SBF over allegations of concealing details about a $40 million transfer to Chinese authorities.
“Come on, CZ, don’t you have better things to do with your time than this?” SBF’s monitored account posted to ZachXBT.

The comment followed a heated back-and-forth that began when ZachXBT challenged SBF over a 2023 BBC report alleging that the FTX founder had authorized a bribe to unfreeze $1 billion in crypto funds held by Chinese officials.
ZachXBT wrote: “Riddle me about the $40 [million] transfer to Chinese authorities you hid from the public.”
SBF’s account responded: “Chinese exchanges stole $1 [billion] and offered to give $960 [million] back. What should we have done — said ‘nah, keep the full $1 [billion]’?”
The exchange quickly escalated.

ZachXBT replied: “A Bahamian exchange stole $8 [billion] and offered to give users only a % back. What should we have done — said ‘nah, pardon the founder’?”
SBF then fired off the now-viral message invoking CZ’s name.
ZachXBT shot back, referencing SBF’s long-running feud with Binance’s founder: “After three years, you somehow still dream about CZ every day.”
Adding: “You only have 22 more years to continue those delusions.”
While SBF’s “Come on, CZ” remark may have been sarcastic, it comes amid renewed tensions between the FTX estate and Binance.
Last year, FTX sued Binance and CZ to recover assets linked to pre-collapse dealings, alleging that $1.8 billion was “fraudulently transferred” by FTX management to Binance.
Rival exchange Binance, led at the time by CZ, initially moved to acquire FTX’s overseas arm as the company faced a liquidity crisis in November 2022, but withdrew from the agreement shortly after announcing the plan.
“By this lawsuit, the Plaintiffs seek to recover, for the benefit of FTX’s creditors, at least $1.76 billion that was fraudulently transferred to Binance and its executives at the FTX creditors’ expense,” FTX administrators stated in court filings.
Despite the lack of tangible proof or evidence, SBF’s cryptic post has sparked widespread online speculation.
In one X post, a skeptical user noted that removing certain letters from ZachXBT’s name leaves just “CZ” writing, “He could be on to something here.”
The surreal exchange also comes at a challenging time for ZachXBT, who recently faced criticism from parts of the crypto community for partnering with BNB Chain.
On Wednesday, Nov. 5, BNB Chain announced that the investigator would collaborate with its community “to help keep the ecosystem cleaner, fairer, and more transparent.”
Many users expressed skepticism toward ZachXBT’s intentions.
One X user wrote: “…you’re just being a hypocrite. If you claim to fight scams, you need a code and a line you won’t cross.”
“Everyone knows what Binance/CZ are, yet you never wrote a word about it despite having receipts,” they added.
The investigator, who remains pseudonymous, has not directly addressed SBF’s insinuation.
