I think players will flee in this situation, considering the large amount they have to pay to withdraw their money from this casino.
I dont think they have real player, or they are not using bitcoin but only altcoins.
After visiting their website I saw their live betting update is not very active and bitcoin is not last used coin.
Both casinos and exchanges have one thing in common though: withdrawals are not in their interest.
Some casinos are better than exchanges and they dont charge any fees for withdrawals, you can see that in first page of this topic.
