Less volatile, low fees, fast confimations time are the things that we should search before decided to pick which coin is suitable for gambling purpose. For me dogecoin is the best one so far.
What's the difference?
You will deposit some funds, doesn't matter which cryptocurrency, you will lose or you will win and cashout, it's not that you will gamble for a month with that money.
Or you are one of the guys who are thinking that gambling with 100$ worth bitcoins isn't the same as gambling with 100$ worth doge or 100$ worth ethereum? It is all the same.
