I don't really think so.
IMO most of the current coin is an-average coins being listed on the casino, I guess they only listed the most regular coins listed on all casino. So, If user want to moving from one casino to other casinos.
They no need to go in exchange first, since you can make a direct transaction between the casino. Remember, add a coins need a few years in "Stake" ~XD.
