Good idea but not necessary there's a cons and pros such as it can be used to money launder but at the same time it can also have extra profit through exchange fee but so far they have a BTC LTC ETH and USDT which is for me is enough since I don't use other coins aside from BTC, LTC and USDT they also don't limit in cryptocurrency but have a flexible deposit. I was curious does the players can withdraw their crpytocurrency to back to bank or only cryptocurrency wallet?
