That is a very nice challenge, I think I will give it a shot. But what if this site is not going to pay me???
Duelbits had given away prizes way more than what is offered recently. If you are around during the previous holiday season, Duelbits gives away more than $100k in prizes, not including its art contests and other stuff. So you need not to worry if Duelbits will pay or not. It is certain, the casino will pay.
