If you are offering "0% Fees" how are you planning on making money?
If your casino is offering PvP games, it would make sense to have lower fees than "traditional" bitcoin casinos because players are not playing against you, but some fees would still be appropriate because you are providing a service and venue.
0% Fees is short term to attract players and money isn't the biggest concern, if it was it wouldn't have taken almost 3 years to develop if it makes money it makes money, I am going to try and keep this project running for a really long time. The goal is to build reputation and trust between the players as this popped out of no where and people have suspicion. I will be doing giveaways quests and puzzles over time to hopefully attract players :^)
