Crypto has never gone through a major economic crisis and when there were short term panics it always dropped significantly. Being without a central bank also means there is no limit to how far it can drop.
Do you mean there haven't been major economic crisis related cryptocurrencies or we don't know what happens to cryptos if (and when) a major, general economic crisis happens in the world? I'm interested in what would happen in the latter case. Probably cryptos would crash even harder but are there cases where people would trust cryptos more than cash in crisis?
It would recover later probably if investor confidence is not completely destroyed. Because as we all know, the entire space is still completely without any real world use case and entirely useless other than speculation.
