Bitcoin prices will probably crash if that type of QC gets discovered overnight, so will the stocks market. QCs are after all not the primary threat to Bitcoin, but to all existing internet infrastructure.

centralized organizations---military, corporations, banks---can harden their systems extremely quickly if necessary. bitcoin cannot. millions of coins will remain vulnerable.

I wouldn't really believe that the adversary, if it's a government would truly be interested in attacking Bitcoin as it's merely a low hanging fruit with fairly low rewards.

how about in 10 years? how about when bitcoin is bigger than gold's market?

i just don't understand the blind optimism. everything boils down to "even if it happens, nobody cares enough about bitcoin to attack it" or "everyone on the network---including the former owners of lost coins?---will magically move their coins the second before QC is a real threat". neither of those are believable to me.

Good point, but you forget that race attack can start when quantum-resistant address is available for use. If it's deployed before quantum computer with sufficient qubits exists (some source mention 1500 qubits for 256-bit ECC), then the owner have big start.

right, and you think that applies to everyone on the network? is satoshi gonna move his coins to quantum-resistant outputs too?

If QC technology is used to crack bitcoin private keys, it will probably be too late to move away from EDSCA and confidence in bitcoin security will be lost/damaged.

+1. the inertia around this subject, and the blind optimism that it will never have real consequences for bitcoin if we do nothing, is very frustrating to me.
