Could I make a suggestion? Perhaps make a contest with a larger amount as a prize but only those who deposit a certain amount are eligible to win. I feel the majority of those who are going to be enticed by a 0.0001 BTC giveaway will likely not deposit significant amounts of funds in the future.
Good idea ! thank you.
I'm currently working on a tournament version of the game, If everything goes smooth it will be available starting the end of next week
