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?
In my opinion if global economy will crash definitely Bitcoin and other crypto will crash too, and i think it would be hard for Bitcoin to recover cause will priorities their basic need rather than digital assets.
But you are leaving out the most important part, if we take a look at what happened during the crisis caused by this pandemic we can see that there was in fact a crash but after it we saw a meteoric recovery, and it is not difficult to guess that something similar will happen the next time there is an economic crisis, the fundamentals of the economy are bad, there are raising prices, unemployment and many small businesses are disappearing, if that was not enough countries are heavily indebted and consumer spending is low, this tells me a crisis is coming and when that happens people will do what they can to find a way to protect themselves from it and bitcoin will be there to help them increasing its value in the process.
