What is likley to happen to BTC in the imidiate aftermath of a global economic crash, and what will a recovery look like in comparison to the economy?
Look at Cyprus in 2013, exchange controls etc. Look at the totalitarian takeover of Hong Kong, and Venezuela, if bitcoin had been around. Smart people will have some of their assets in a portable, non-censorable asset like bitcoin to protect themselves and provide an escape hatch.
Bitcoin will do just fine and survive. Who knows about the fiat price, of course, but bitcoin itself will be fine.
