People do not believe in crypto currency. They say that crypto is not fixed. As fiat - gold. Where does the value of crypts come from? What do you tell people?
I don't quite understand your question completely, sorry!
Those who don't believe in cryptocurrencies don't seem to really understand it. Maybe it's just a mixture of investments and stocks, funds, and futures. This is a mistake. They should first understand the origin of Bitcoin and talk again!
