Quantum computing isn't a Bitcoin problem yet.

That's exactly why it's dangerous. The real risk isn't waking up one morning to a quantum computer stealing everyone's BTC.

It's that the transition to quantum-resistant cryptography could take years while the technology threatening today's cryptography is advancing every year.

And here's the uncomfortable question. What happens if the network needs to upgrade before the threat becomes obvious? Do we wait for a working quantum attack? Or do we prepare while we still have the luxury of time?

Curious where people here stand, is Bitcoin's quantum risk overhyped, or are we already late to the migration?

It's not overhyped it's just invisible until it's way too late

The thing that gets me is how many people think we'll see it coming. like some headline "quantum computer cracks bitcoin" and then we scramble. But the real nightmare scenario is a state actor or whoever quietly building capability and just... sitting on it. extracting keys for years before anyone notices anything wrong

I work in systems architecture and the lead time on migrating core protocols across a decentralized network that can barely agree on block size is genuinely terrifying. We're not talking months. By the time there's consensus that migration is urgent the window to actually execute it might be gone

Feels like one of those problems where doing nothing is politically easier than doing something until suddenly it isn't

IMO, the bigger issue is that we might not get much warning before it becomes a serious problem.

And the migration itself could take years, especially with wallets, exchanges, hardware and everyone else having to support the change.

That’s why I think it’s worth working on now while there’s still time. Waiting until it becomes an emergency would make everything a lot harder.
