people dont believe in the capability and existence of crypto. some said that its waste of time knowing this kind of currency. they believe that this is some kind of invented kind of money,.
In my opinion, I think that people do not believe in cryptocurrencies for the reason that they do not know anything about it, and if they do, they think that it is irrelevant. Most of the people are still into fiat money, and only few people know about crypto so I am not surprised that something they know nothing about will make them invest or get involved into.
