You have not experience casino who pays the withdrawal fees for they players? Try sportsbet.io. how could you miss it lol
I have used Sportsbet several times to win free bets in bitcoin, their withdrawal fee for bitcoin is 0.001 BTC. If I do not win up to the price, I will not be able to withdraw.
I prefer casino who allow small fees just to pay the network cost. Some casinos makes it as another revenue streams which is bad.
J do not think it is bad if the difference is not much. Like if bitcoin network fee is $0.1 and the casino charges $0.5.But people will have their own preferences.
