#钱包安全漏洞 This wave of quantum threat discussions, after all these years observing the ups and downs of the crypto world, is essentially just old wine in a new bottle. Quantum computing cracking Bitcoin by 2026? Industry consensus is already very clear — it will take at least another ten years to become a real threat. Currently, 90% of the hype around this topic is just marketing gimmicks.

But that doesn't mean we can relax our vigilance. I have experienced the exchange scandals of 2011, the Mt.Gox collapse in 2014, and various wallet vulnerability incidents since then. Each time, I learned one key lesson: the real threat often isn't how strong the system itself is, but the weak links in human nature. Now, there are addresses with exposed public keys holding 4 million BTC, which is a signal that history might repeat itself.

The most critical insight is the attack scenario of "collect first, decrypt later." This isn't something that will only happen in 2026 — it's happening right now. Just like back then, when we watched cold wallets gradually exposed through exchange hacks but couldn't respond in time — history repeats, only in different forms. The old problem of address reuse has become a fatal flaw in the quantum era.

My advice is straightforward: don't wait for quantum wallets to mature before migrating — it might be too late by then. Now is the time to clean up addresses with exposed public keys and diversify holdings. This isn't paranoia, but a necessary caution learned from past lessons. The rules of cryptographic security have never changed — you must always stay one step ahead of threats.
