Well, if you transfer real time and you'll take and convert it into your main coin.
It doesn't matter whether it is ltc or doge. As long as transfer is very quick and cheap.
You can't control the volatility of a certain coin, it could drop 10% to 20% in just a matter of minutes, or the opposite could happen. Just face the reality that volatility is here, you don't only play to win in gambling, you also play to win the volatility... if you want ot stay out of volatility, then use stable coins in gambling.
If it's the volatility that's being concerned, you should stick to the fiat-deposit option of the casino or yeah, stable coins.
We gamble and deposit with the amount that we've decided to transfer and that's the quantity that we've already thought of. The concern of mine is just all about quick and cheap transfers.
Stable coins also have a stable transaction fee, especially if under erc20 tokens.. I guess altcoins with cheap fees are still favorable, especially for gamblers with small bankrolls in gambling. Well, we just have to analyze in what way we can save money, otherwise, we will already lose money the moment we make a deposit due to high fees.
