Haha...I wouldn't single out any of them because the end of the day it is money we're talking about. And don't forget Cryptos can be bought to in s much as Fiat has a quality of being difficult to get. If it's your money then it's your money That's how i see it. Coz using $100 worth of BTC for betting wouldn't be any different from using same $100 in Fiat.
Whether fiat or cryptocurrency, both are money and none is bigger than the other when trying to earn it or get.
Moreover, you don't have to gamble with $100 before you gamble. One can gamble with as little as 10 dollars and still earn some money. It's all about the strategies you use.
The bigger the amount you've spends in gambling, the more you'd think to win also but it wasn't just easy, and the risk of loss will also be bad.
If we would like to be in gambling and spend money, please see to it it won't comprise any, not from lending institutions nor a borrowed money from your friends cause we know already the possible result and I don't want to see people been in regrets just because of this.
