A jackpot takes away from getting paid out and with 1.00 btc it isnt worth making a jackpot
That's the wrong philosophy, though. You need people to invest to make any profit, and if there's no jackpot, there's no incentive for anyone to invest after a certain point, which in your game is right at the beginning.
When I made my game, I took this into account, and it currently has 15 investors (including me a few times). The biggest problems with my game are that there are 1% transaction fees (psychological deterrent, doesn't actually produce much profit for me - also it creates a mess in my BTC client) and that it lasts 72 hrs, which is probably too long. The two other games with similar structure to make are also doing very well (I won't name any of the three to avoid advertising on your game).
