In my opinion, the main driver for people loving cryptocurrencies is because of the profit they make from it, and not because they think crypto is the future. For example, if Musk thinks that crypto is the future and he knows that he can move the market, by exchanging all his fiat money to crypto will see crypto value take off like a rocket, at least for a period of time. For many, cryptocurrency is easy money, where you invest in some machines that will then passively generate extra income. Or they invest in it and hope that it will appreciate drastically due to its crazy volatility. So while they claim how good cryptocurrencies are, those are not the main reasons why they are so into crypto.
