Binance founder Changpeng Zhao, known as CZ, has pushed back on growing fears that artificial intelligence could crack Bitcoin and other crypto networks.
In a recent post on X, he noted that the internet and banking systems rely on weaker encryption, even as worry about AI hacking crypto spreads.
“Everyone worried about AI hacking crypto, but the internet and banking systems rely on weaker encryption,” he wrote.
Zhao's point is that AI does not need to break Bitcoin's cryptography to cause damage.
Leaked data, he said, already enables more phishing and social engineering. In other words, the weak point is the person holding the keys, not the code. He signed off with "Stay SAFU".

“AI doesn’t need to break Bitcoin’s cryptography to cause damage, leaked data already enables more phishing, social engineering, etc,” CZ said.
The warning matches his earlier advice to users: avoid clicking links in emails and use hardware security keys such as Yubikey, which he said block most phishing attacks.
In an earlier X post, Zhao posted a broader reminder that no crypto wallet is fully safe, no software is free of bugs and no technology is completely secure. Risks exist in everything people do, he wrote, and also in doing nothing.
Problems and setbacks will come. His advice: stay updated, manage risks and solve problems as they arise.
In the post he wrote, “No crypto wallet is 100% safe. No software is bug free. No tech is 100% secure. There are risks in everything you do. There are risks if you don't do anything. There will be issues, setbacks and problems to solve. Stay up-to-date. Manage risks. Solve problems.”
Taken together, the posts shift attention from a distant technical threat to everyday habits. Users who reuse passwords, click unknown links or share personal details online give attackers plenty to work with.
Users should treat unexpected emails and messages with suspicion. Security, in Zhao's framing, is an ongoing routine, not a one-time setup.
