We need to see what are the currencies are accepted on the gambling site we choose to play for because of most gambling sites have bitcoin and other few currencies as accepted. Basically there is no issue with gambling on stable coins but if you won billions in stable coins and wanted to cash out on any exchange you may face issues regarding KYC and others so stick with bitcoin so you can convert them into money if you won in millions.
Well thats an another story if you do win up stablecoins but i do only see a few who do accept stable coins atm yet most of them do really have that common payment of BTC and other top alts as well.
When it comes on my gambling activity it do really indeed vary on whats the site is requiring but if i dont have a specific coin that they do ask out then i do simply skip out yet sometimes
i dont really like the feeling on spending up some btc but rather do like to play up some doge.This is why i do much prefer on some sites that do have internal converter to other crypto coins as well.
Internal converters actually is a good feature of a casino. Also, when you decide to withdraw your funds, you can select options other than bitcoin. And while you are playing inside the casino, you feel you have a lot more money if you have doge, based on my experience though.
Anyway, if you won large sum of stable coins inside a casino, you can always convert to other alt like eth or btc or whatever is available within the casino that will not cause you any trouble in withdrawing your funds.
