if bans or ever simple regulations leads to killing of any cryptocurrency then we should stop using them right now and right away without losing any time because we are wasting our time on those.

the start of cryptocurrencies with bitcoin was mainly for the purpose of creating a decentralized payment system which can remain censorship-resistant. and that means any ban or regulation should not affect said cryptocurrencies. and if it does then something seriously is wrong with them.

as you can see the "real bans" of bitcoin has never affected bitcoin at all. people in those countries (which i bet 99% of people don't even know these countries) are still using bitcoin.
the "fake bans" like the China, Korea, Russia,... bans are causing drops because they are FUD.
