I guess we can go back to the height of bitcoin during 2017, we all know that confirmation times is so f** slow, I myself experience days withdrawing. So if you are a gambler and the casino that you are playing have options like ethereum, doge any other crypto's besides btc then I guess it will come in handy when that kind of scenario happened again in the future. At least you don't have to wait for longer confirmations times that might affect your playing habits though.
