I also think that way, that paper money is better than crypto. The reason is because my country does not accept payment using crypto. So paper money looks better than crypto.
Honestly, I am not even sure abbot the percentage. Those people who are investing in crypto currencies consider them worthy of being trusted and money. If they had supported fiat then it is not possible for them to buy these coins. Then there are those people who dont understand technology but I think that kind has still not discovered anything about digital market.
