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.
Bitcoin is very expensive and day by day price of bitcoin is increasing so it is not good to spend your bitcoin on useless things, try to save and spend only money for gambling but bitcoin is not suitable for gambling at this moment. As we know we can use so many other coins which cost low price for gambling which can make money for us.
