Can i give my opinion?

1 - Your rewards aren`t so attractive
2 - Your design not so much attractive
3 - We have not sure if you`ll honor this free btc contest
4 - Long time to finish, you should make it dynamic... maybe share this rewards for 0.01BTC every 2 days for 2 weeks (reset point count after each round), i have sure you`ll get more player than waitting 2 week..
5 - Maybe changing you contest, on really playing with a ~fake~ money not so attractive, not cool... maybe making new user signup btc bonus or something like that more interesting


Hope your business can survive, good luck
