I am sorry for criticizing your "beloved" project but being a responsible bitcoiner, I must talk what I feel.
I like you to invite you to your own topic:
https://bitcointalk.org/index.php?topic=5118164.0 and please answer all the doubts by providing proof (for example, for previous pay-outs ) then I promise that I will DELETE my all posts in this topic.
We are a new platform, growing day by day, taking users feedback and making improvements. However, we do not care about Irrational criticisms of our project.
With regards to payouts, the funds are added to user accounts of users who got winning tickets. The user then decides what he/she does with the funds, it can be withdrawn or use in placing more bets.
Requesting for payment proof is essentially requesting for all withdrawals processed by our service. Which of course doesn't make any kind of sense. You are more than welcome to provide any user of any other form of evidence of us not making payouts, as we process all withdrawal request every hour.
