I've been hearing a lot lately about how quantum computers might threaten Bitcoin. But in reality, I think that sense of crisis is being greatly overestimated.

Looking at the latest report from CoinShares, there's some quite interesting analysis. It's true that theoretically, about 20% to 50% of all Bitcoin could be vulnerable to quantum attacks, but that's a different matter from the actual market impact.

Specifically, about 1.6 million Bitcoins stored in old P2PK addresses, roughly 8% of the supply. That part is factual, but what's important is what comes next. Among these, only about 10,200 BTC are at risk of being stolen in a way that could cause significant market chaos. The remaining funds are spread across more than 32,000 addresses, averaging around 50 BTC each. Even if quantum attackers try to decode these individually, it would take too long and be too inefficient.

Furthermore, breaking Bitcoin's cryptography apparently requires a fault-tolerant quantum system with about 100k times the performance of the largest current quantum computers. While Google's Willow has 105 qubits, Ledger's CTO points out that actually cracking the keys would require several million qubits, which is convincing. In other words, this threat is at least over ten years away.

Therefore, the key is not to treat this as an emergency but to approach it as a long-term engineering challenge, gradually addressing it. Proposals like BIP-360 exist, and planning a transition to post-quantum signatures should be more than enough to keep pace.

It's understandable that Bitcoin's price volatility draws attention to various risk factors, but regarding the quantum threat, I think we need to stay calm. Market anxiety and actual risk assessment should be considered separately. Currently, Bitcoin is trading around $74,240, and these technical concerns might be influencing the price fluctuations.
