I have contest idea for primedice. Every player in the contest gets a set amount of fake btc to gamble with. Every player pays a entry fee to be in the contest. They all gamble for a hour and the highest balance wins 80% of the entry fees. Before, during and after tips, deposits and withdraws are disabled until contest winner is decided.
Just a idea.
20% fee for running the contest?
And I think many people will complain about not being able to bet.
