The more the merrier. I think adding more crypto currency in your casino currency is always a good idea for gamblers since they can deposit their altcoins holding without the need to convert it to currency that casino supports.

I knew one casino that adds bunch of altcoins even low caps that impress me since I can directly deposit my shitcoins investments to casino and gamble while still holding my original investment. @Coinbox1 just keep adding coins because this update is always appreciated by players.
