> Can the government seize Bitcoin directly? No.

A government could seize miners, and given that ~50% of the world's Bitcoin mining capacity appears to be located in one country, that might give them considerable leeway to rewrite the blockchain to their liking.

Yes. The solution to this is a software fork.

Did you mean "soft fork", or are you thinking of a different concept I'm not familiar with?

Forks can and have been used to deal with isolated malicious incidents, but do you think they can be successful against an actor in extended control of a substantial part of the hash rate?

[doggosphere]

You can alter the hashing algorithm to one that is more ASIC resistant. Monero did this.
