Bitcoin collapsing would be funny, in hindsight. Probably a pretty emotional event for some in the moment.

But banking is already not that secure. Credit cards suffer from massive ongoing fraud. Especially in places like the USA where chip systems are less common.

There is still a pretty sizable difference between “a patchwork system that fails a lot in small ways” and “you can’t use a computer for anything financial, ever”.

I get the impression that the community would have enough consensus for a snapshot at a certain block number, and continue the chain with new quantum resistant keys

I think for the attacker with a quantum computer, they will need to steal low amounts for a long time so that people brush other user’s missing funds off as user error

But these investigations often do quickly give users the benefit of the doubt so I would see the network being at high alert really quickly

Chip is fairly common nowadays in the USA.

Fraud liability was shifted from card brands to retailers if they don't support chip. That was a big deal to start supporting it.
