I think the best question should be, "how to increase my chances of winning at gambling?"

Technically, using fiat or crypto won't change the chances of your winning. You are still gambling regardless of the currency you used.

If you come back here with that question I mentioned, tell us the specific gambling game you preferred to place a bet then we will give you some pointers on how to increase your chances of winning. But remember, if those are luck-based games, there's no way you can increase your winning chances there.
