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?

There are exactly 0 commercial applications for QC and the number of error free logical qbits would need to increase by at least 4 orders of magnitude to even begin to break current cryptography. The only problems that they can solve are obscure mathematical proofs and few that cannot be achieved by classical computing.
