The fact that you keep saying the word "cryptos" which is too vague to have any meaning in 2021 and keep talking about this imaginary conflict between "cryptos" and fiat, tells me you are firmly stuck in 2017 and have no idea what's been going on in this space. First, I don't own Bitcoin. I got into this space for smart contract driven blockchain technology, not fiat replacement. I hold a fair number of tokens. Some of those tokens represent protocols that earn more revenue than 30+% of the companies in the S&P500. None of the tokens I hold are trying to be or replace money. All but 1 aren't even blockchain tokens, they are protocol tokens. I fully expect to move my fiat into and out of tokens in the same way I move my fiat into and out of stocks, commodities, bonds and real estate. No difference. All of that being said, if someone believes in the Bitcoin narrative and wants to move some of their fiat into it, more power to them. And if they happen to make huge profits then I'll celebrate with them.
