#恶意攻击手段 Recently, I came across a somewhat terrifying topic—will quantum computing crack Bitcoin? 😰 As a newcomer to the scene, I instantly panicked, feeling like my assets might be unsafe... Later, after carefully reading experts' opinions, I finally relaxed.

It turns out that in 2026, quantum computing breaking encryption is still mainly a theoretical threat, and the real danger might not appear until ten years later. But there was a detail that scared me—about 4 million BTC are stored in addresses with exposed public keys, which indeed pose a higher risk 😅

More importantly, I now understand that attackers' current strategy is "collect data first, then decrypt once the technology matures," kind of like laying a long-term trap. So besides waiting for quantum-resistant wallets to go live, what we can do now is: **Don't reuse the same address**. This advice is super important for beginners!

It seems the crypto community has already started to prepare—some projects are upgrading their defenses. Although there is no urgent danger, this reminds me to pay more attention to wallet and address security management. Can experienced users explain what exactly counts as "reusing an address"? Does it mean receiving multiple transfers to the same address? 🤔
