I bought some cryptocurrencies at the worst time possible, right before the big crash in 2018. However I still consider them a good investment. Fiat currency in my country is plummeting rapidly so I think one of the good options is to invest in cryptocurrencies, especially stable coins that don't fluctuate like bitcoin. In economic crises, investing in cryptocurrencies besides gold and real estate is not a bad choice IMO. Also for transacting in short amount of time and with a meager fee, cryptocurrencies are the best.
