With your thread I can say that you strongly believe in Fiat currency than crypto currency and I don't know the reason for your decisions but crypto is better as pertaining the privacy and security but you don't get that with regular fiat casinos which is why you need to trust online crypto gambling and talking about coins not having value,how about trying stable coins and see the outcome.
You are quite right however both crypto and fiat casinos have their distinct advantages and disadvantages. However since we are currently in a dynamic era, people tend to prefer crypto currency accepting casinos to regular fiat casinos based on different reasons. One of them is the fact that fiat casinos usually tend to have. Bigger percentage allocation to taxes, compared to crypto casinos on the other hand which usually has very little or no tax at all. Another importance is the convenience of crypto casinos over fiat casinos since you are able to deposit funds into your casino wallet any time and anywhere without any form of fiat currency restrictions.
With crypto casinos gamblers are able deposit in crypto currencies and still stake with the individual rates of their local currencies.
