What currencies do you use to bet in the casino? USDT, BTC, BFG?

I've notice that in some games (such as dice or dicespace), if I'm using USDT, I can't bet less than $1, which is too much in my opinion, because if I have set a % increase in the bet amount on a win or loss, this value can become very large and run the risk of breaking the bank, I saw that with BFG I can bet with $0.001 if I want.
