The reward now might only be enough for some gas fee and can only sustain few minutes of gaming in any casino or just second depending on how big we bet, however it can still be a good way to acquire more btc of crypto. Since the price of crypto were too volatile now and better to do trading, i would rather hold it in the meantime or use for my trading transactions.
Maybe yes it is more practical if we use altcoin in our bets rather than our bitcoin salary (assuming that it is btc since most of our sig camp now pays in usdt or tokens), I want to save more bitcoin maybe convert some into xrp or doge if I want to use it in gambling but most of the time I am not using my earning to play, because it is risky for me and the price of altcoin are pumping now so when I lose the greater decrease in my assets, so I rather put it in investment.
