Changpeng Zhao says thereโs no need to panic about quantum computing, as its real impact on crypto security remains limited for now.

Steady attention without excessive speculation.
1 April, 2026: Changpeng Zhao (CZ), founder of Binance, has stated there is no need to panic about quantum computing threatening cryptocurrencies. In an X post, Changpeng Zhao, founder of Binance, said that cryptographically relevant quantum computers capable of breaking current blockchain security remain many years away. He reassured the community that the crypto industry has ample time to migrate to post-quantum resistant algorithms before any real threat materializes.

@cz_binance "So, no need to panic. ๐" That is oversimplified and a false sense of security. Even with a quantum solution in place, all of the lost (millions of coins) and unmoved coins (think satoshi's wallets) could be confiscated by quantum computing and dumped onto the market. So,
Saw some people panicking or asking about quantum computing's impact on crypto. At a high level, all crypto has to do is to upgrade to Quantum-Resistant (Post-Quantum) Algorithms. So, no need to panic. ๐ In practice, there are some execution considerations. It's hard to

@cz_binance Locking Satoshi's coins is unrealistic. Bitcoin has no mechanism to selectively freeze addresses. The only scenario where this happens: a state actor cracks it first with quantum and migrates everything into a new centralized system. And if Satoshi's coins ever move. That's the

@cz_binance So let me get this straight if satoshi moves his funds, bitcoin is fucked if he doesn't move his funds, bitcoin is DOUBLE-FUCKED got it

ฦThe idea that quantum computing could threaten blockchain security has been around for years. In theory, powerful quantum machines using Shorโs algorithm could break elliptic curve cryptography (ECDSA) used to secure blockchain signatures on networks like Bitcoin and Ethereum. Because of this, every new breakthrough in quantum tech often triggers fear and uncertainty in the crypto space. Hash-based components such as SHA-256 are not vulnerable to Shorโs algorithm in the same way.
How CZโs view reframes recurring quantum-computing fear in crypto markets
While the message of Changpeng Zhao is reassuring, the theoretical risk to current elliptic curve cryptography remains real. Cryptographically relevant quantum computers running Shorโs algorithm could eventually break the private keys of most blockchains, including older Bitcoin addresses that have exposed their public keys.
The crypto industry is already researching post-quantum algorithms, but a full migration across decentralized networks will be technically complex and require years of careful coordination. Until clear upgrade roadmaps and on-chain activation plans are in place, some long-term uncertainty will persist despite CZโs calm outlook.
