how about leverage additional coins to use as clam? and then winnings are in clams, and loses get sold off for clam
this way if an exchange is down, players can go without waiting
What do you mean, an exchange inside the casino, like in Crypto Games or Luckygames?
In my opinion, may not be a bad idea to have an exchange that's centered around clams. That way it'll be easy for people who don't have clams, but have btc or other coins, to convert and start playing immediately.
Just my 2 cents...
