Recently, there's a topic worth discussing— the threat of quantum computing to Bitcoin security. David Duong, the research director of a leading compliant platform, recently issued a public warning that approximately one-third of Bitcoin could face risks from quantum computing attacks.

Why is this so serious? The key lies in the fact that the development speed of quantum computing is much faster than market expectations. What was just a theoretical possibility a few years ago has now evolved into a tangible risk. Specifically, Bitcoin wallets with public keys already exposed on the chain are most vulnerable— once quantum computers become powerful enough, they can easily crack elliptic curve digital signature algorithms to obtain private keys, leaving the funds in the wallets at risk.

Research institutions predict that this cracking capability could be achieved within 4 to 5 years. Even traditional giants like BlackRock, when submitting trust fund documents in May, specifically listed quantum computing as a major risk factor. This is not unfounded; the entire industry is taking this seriously. If your Bitcoin address has ever been used for a transaction, the public key has already been exposed, so you should stay alert.
