What other cryptocurrency are you using and which casino are you playing at? BTC is getting to expensive to be depositing and playing in just BTC.
Bitcoin is constantly increasing in value and I do not think it is wise to gamble with, especially if your purpose of gambling is to get enjoyment and fun. I would suggest to use Doge coin instead, as it is the cheapest coin and there is hardly any charges for depositing and withdrawing Doge.
Yes, you are right today the price of Bitcoin increase too much high and it is not a good idea to spend Bitcoins in gambling because transaction fee might increase. So it is good to have fun with the Doge because the value of Dogecoin is very low in the market.
As a gambler we should smart and it is true, bitcoin is getting expensive and most of the gamble can't play with bitcoin, because it is out of afford then better to play with other coins and now i agree with you doge is better to play gambling.
But i suggest you richest gamblers who have don't matter of money, they should play gambling with bitcoin, because in betting with bitcoin and if win then too much good to make your bitcoin double.
