I think cryptos will replace FIAT in few years. It will be an hard trip and fll of problems, but there is no sense to continue with a government-centralized currency. that's why I'm motivated to invest into cryptos, and I don't care about crypto fluctuations. I just HOLD, the time will come..
It is OK to believe in Crypto but I do not think it will replace fiat ever. Fluctuation is the nature of crypto, this is the main reason why crypto cant replace fiat. But if you do not care about the fluctuations then how will you make profit? HODL till the time is come? No specific target of profit or how long you'll hold?
