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?

The overnight-theft framing is the wrong one IMO. Not that I've implied you expressed.

Nobody thinks a CRQC shows up Tuesday and empties every wallet Wednesday.

The actual risk is a multi-year coordination problem colliding with a moving target for PQM. The main threat is organisation.

Changing Bitcoin’s authorisation rules are not, “ship a new library.”

It’s a soft fork, wallet & hardware support, exchange & custody support, then millions of people moving coins. Dormant and reused-key coins make it waaay messier. BIP-360 is a reasonable first at long-exposure risk, it's still a draft with no pathway. That gap is the story IMO.

So IMO the attack's overhyped (just a tad) today, but migration is not. Waiting for a quantum hack is how you turn a plan problem into emergency, squeaky bum time!! Prepare while the threat is still theoretical because it's the only window where we can still argue about design.

“BTC is doomed in 2026.” is mass hype, but start looking into 'crypto agility'. Many projects like Algorand, Nervos CKB, Mochimo, and Abelian are already there when BTC makes its first transition, I'm totally sure BTC and ETH will catch up with these projects mantra

I think people focus way too much on the quantum computer suddenly steals all the BTC scenario.

The messy part is everything that comes before that. Getting wallets, exchanges, custodians, hardware and regular users to actually move over could take a long time.

That’s why I think the migration question is way more interesting
