1 BTC Raffle - www.stakeabit.com

The idea is good.
But if you do some changes then it may get better response IMO.

1. You have to make sure that the system is provably fair.

2. You can keep the option to buy stakes in several values. Such as BTC0.00010000, BTC0.00050000, BTC0.00100000 and so on.
    In this case, you may bring add funds system instead of direct buying / deposit option.

3. At least make 10 winners in a round instead of 1 winner.

4. Escrow some funds for some months to gain trust from your users.

5. The platform should be highly secure as the users will make deposits.

6. And the last thing will be needed is a good marketing plan.

0.0015*999=1.4985BTC total stake and only 1 winner who will get 1BTC, means that you will take .4985btc for every draw? I dont what I should call this, maybe fees or house edge but it is just too high for such raffle. You are going to take more than 30% of the total stake. How could you think that it will attract players? I do not even think it will happen after months or years, you should reconsider and revise your project.
