Quantum Computing Breaking Bitcoin in Seconds? That's Not Really How It Works

Honestly, how powerful are current quantum machines? Give them a simple task—calculate what 21 equals (3 times 7)—and they still have to "guess." If you really expect this thing to break SHA-256, you're completely dreaming.

The obvious technical challenge: Grover's algorithm theoretically requires hundreds of thousands or even millions of perfect qubits. But in reality? The industry's top level is only a few hundred noisy physical qubits, which are nowhere near the same scale. Plus, Bitcoin produces a new block every 10 minutes, and you need to compute the private key in real-time within this window—that gap is at least 20 to 30 years to bridge.

So, your Bitcoin is safe for now. But the problem lies ahead—what if someone intercepts your data first, and when the quantum era truly arrives, they slowly decrypt it? That becomes a sword hanging over your head. The industry has already realized this, and the race to upgrade cryptography has begun.

What do you think? Is the "quantum threat" exaggerated, or is it something we really need to prepare for? Share your thoughts.

Haha, coming with the same routine again? I'm already tired of hearing it; it's just FUD and FUD. --- It's been twenty or thirty years, and we've already gone through countless transfers of our coins. There's really no need to panic this time. --- The industry has been advancing in cryptography upgrades for a while, but we must admit that there are still pitfalls in post-quantum cryptography. --- Basically, it's a matter of time difference. Some people are hoarding data now, waiting for future decryption, and that's the real heartache. --- The design of one block every 10 minutes has really cornered quantum technology, and we must respect Satoshi Nakamoto. --- The shortcoming of noisy qubits is hard to bypass; it seems this hurdle isn't so easy to overcome.

Ha, it's the same old story. I analyzed quantum matters two years ago, and back then the technical aspect was just weak oscillation. It's still the same old situation now.

In short, it's just a false alarm. Currently, quantum cannot break through, and the future is still a long way off. We're still in the stage of unnecessary worry. Hey brother, isn't this just hype about concepts? It's a routine to scare retail investors. Wait, the post-quantum threat part is worth pondering. Twenty or thirty years? Then I’ll be long gone haha. Quantum research is like this: papers are hyped up wildly, but the technology is ten thousand miles behind. Actually, the most concerning thing is that now data is being eavesdropped and stored, waiting to be decrypted once quantum is broken. That’s a pretty ruthless tactic. If it can't break SHA, then forget it. Plus, it has to wait for a 10-minute cycle, which is extremely difficult. Alright, better to prepare in advance, but don’t let those quantum news mess with your mindset.
