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
my opinion
1 - could be right
2 - design doesn't matter
3 - he could escrow but IMO not needed because if he doesn't pay this small amount he is KO in first round
4 - agree...... 1 or 2 day contests
5 play money should be fine for all as long as real prices are paid out
