Guys we created a jackpot draw. It works very simple. People can make a contribution to a pot. Every 7 days we select 1 winner who receives all the money that is in the pot. The probability of winning is determined by your contribution to the pot. We were inspired by this article: The Perfect Lottery — Ethereum contracts enable trust and maximum payout
