It's good until it's not. A successful quantum attack on a bitcoin address would end it permanently - sure we might be "decades" away from that, but we also knew it took years to make a vaccine until Moderna/Pfizer made one in ~2 days.

Right now bitcoin is like a castle with massive walls - everyone knows where the castle is and what's inside, but nobody can get over the walls. It makes sense to feel safe from attack. Quantum computers are the equivalent to the enemy arriving to your castle walls with a helicopter.

Tbh yeah that makes sense. But only state actors are going to have first control of a quantum computer... Aka one of the US or China. Neither have a ton of incentive to mess up the chain. Plenty of Chinese have btc and plenty of americans have btc. Idk what do you think?

I think that's correct, but I think the broader point is that unlike gold or real estate or other long-term stores of value, bitcoin has a few improbable but catastrophic ways to rapidly lose value.

Also don't put it past the CCP to rapidly change their mind on bitcoin if they detect that it facilitates capital flight.
