Quantum computing is coming: the security crisis for Bitcoin has been seriously underestimated

【CryptoWorld】Recently, a topic has exploded in the community—will quantum computing blow up Bitcoin? The global investment research director of a major trading platform, David Duong, recently issued a warning, saying that as quantum computing technology becomes more mature, Bitcoin’s long-term security is entering an “unknown territory.”

It sounds a bit alarmist, but data doesn’t lie. The entire crypto market size has now reached $3.3 trillion, and there is insufficient awareness of the threats posed by quantum computing. Duong pointed out that approximately one-third of the Bitcoin supply has exposed wallet public keys, which could face the risk of quantum computing brute-force cracking of private keys in the future.

You might think, isn’t quantum computing still in its early stages? Theoretically, yes, but the problem has shifted from a hypothetical on paper to a real threat. Many believe that the biggest threat of quantum computing is not mining efficiency, but the security of digital signatures. Once quantum computers have enough computing power, attackers could derive private keys from your public keys and directly transfer your Bitcoin.

This is not a new concern. Large players like BlackRock have already explicitly listed quantum computing as a risk factor in their Bitcoin ETF application documents. Some researchers even estimate that quantum computing could pose a real threat to Bitcoin’s cryptographic system within 4 to 5 years. So instead of waiting for surprises, it’s better to start paying attention now.
