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?
Very much possible! During the last prominent economic crisis, we didn't have the option to move to crypto. So most people had moved to so called safe heaven like Gold or other precious metals. Historically, gold has been used as a safe heaven during any financial crisis. I don't think this trust on gold will not end anytime soon and will continue even during the next financial crisis.
But this time, we have cryptos! So its no wonder that a lot of people will flock into crypto market during uncertain times. However, such incident will definitely increase its adoption as well as the price. But considering the price of bitcoin is so volatile, it may scare some people out of the market. Because a safe heaven usually stays stable uring bad times. Bitcoin has not yet shown such resilience and maturity. So a major impact may not happen!
