This looks very suspicious because this website seems like it is brand new and still they are claiming to have a 30BTC jackpot that's going to take place is about 38 hours. They also claim that they have paid other jackpots before to people but it seems impossible to find out who those winners are and a payment proof of their winnings. I suggest that everyone should stay away from this, at last until we get some clarification about the website from OP, because at first it seems like a big scam.
Let us wait for this thing to happen and we will know for sure if they are bluffing or manipulating the numbers. And has anyone tried their free tickets? Most of the time there's a certain catch to it, either you need to deposit to activate the ticket or play first in their platform.
