Honestly, I think that perspective is way too pessimistic. Quantum computing is advancing, yes, but the kind of large-scale, fault-tolerant quantum machines needed to break Bitcoin’s secp256k1 keys are still many years away, likely well beyond 2030. Meanwhile, Bitcoin’s upgrade path is slow on purpose because security is paramount; rushing changes could introduce more risk than a theoretical quantum threat.

Arguing that “a Shor’s attack will come first” ignores that Bitcoin’s cryptography has decades of scrutiny, and any real threat would likely be spotted and countered with post-quantum upgrades well before keys are compromised. The focus on JPEGs or blockspace debates is actually a sign of normal network development, not a vulnerability indicator.

Bitcoin has survived scaling wars, censorship attempts, and economic shocks. Claiming it’ll fall to quantum computers before it adapts underestimates the resilience of the network, the community, and the gradual, deliberate upgrade process.

I like your optimism, but this is something different. This is a math attack. I think most everyone would agree that if a shor's attack comes suddenly tomorrow, that will be the end of Bitcoin. I think most everyone would also agree that if a shor's attack comes in 15 years then Bitcoin will be fine. So there is a point between now and 15 years from now when Bitcoin moves from being ended to being fine. You're betting everything on that point being soon in time enough. I'm guessing it won't be.

With that guess of yours, you probably don’t even have Bitcoin, so gather some fiat. You’ll find out soon.

I think that to get a better answer, you should seek guidance from specialists and experts in this field.

I’ve stated my opinion firmly. You have your opinion, and I have mine.

In the future, we’ll see who guessed correctly. I’m on the Bitcoin side, and I say it always wins. And you’re on the Shor’s attack side.

I'm on the side of math. what math giveth, math taketh away. but let's check back in some years and see, guesses are guesses.

no, it is possible that we will have working machines able to get private keys from old type addresses within 2 years

What is often glossed over is that advances in math are just as serious as advances in hardware. Like a classical algorithm that massively reduces the input size for shors. AI is knocking on the door there.
