l gamble with crypto preferably (USDT) tether to avoid fluntuation of the price of regular crypto like bitcoin, ethereum etc, which I believe is better, swift and faster and can be done anonymously, I haven't tried fiat yet in my country there are physical gambling kiosks and Casinos where gamblers who are not using online sites do go to play their bets and play games with fiat, though I personally detest that idea because of the presence of a lot of people where some don't have any business there, however both methods has equal chances of winning a bet.
