Yes. Back then it survived without any major CEX that time.

So it'll survive even though the countries banned it, the volume will be gone but there are many DEX out there where we can trade BTC and people will just transfer there. There are bunch of DEX today that has perpetual features and they keep improving, we have a lot of options in cryptocurrency. The volume will just get low and of course the price will react but if people learned to adapt to what's the meta, it'll eventually go back what it deserves. The solid foundation of BTC is the community so better be positive about it.
