The cool thing about cryptocurrencies is that they don't obey to the physical market. It won't be effected at all, obviously if we don't have anything to invest that's quite useless, the most anticipated idea is to build a backup now, for those dark times that I hope will come really past in the future
Of course theres an impact whether its negative or positive, we cannot say it unless things happen. If there is a global crisis again I think many investors will come because they think crypto is safe from that crisis or people will convert their cryptos to fiat money so they can secure personally their money. So basically there is effect of global crisis in everywhere and it will depend on how people react on that situation.
