In theory, Bitcoin will take off again, but if capitalists don't want this to happen, Bitcoin will fall. Now that the economic cycle has entered a 100-year cycle, many countries will have huge problems.
Probably Bitcoin wouldn't easily to fall because it's been supported by some big whales as we say. If there is an economic crashed, well or will probably have some reaction and to think it would probably make the value to go down.
Probably depends on what caused that economic crash. Imagine if ww3 broke out wiping most country's economic structures. I don't think even crypto would be able to survive that with basic essentials like online connection possibly becoming compromised.
