I just we t ahead and visited your website to understand the concept. Frankly speaking I do not have a clue how it will work? The next big question that comes to my mind is that how will you guys earn?
What exactly does decentralised means? Your platform is being controlled by you. Which means it is a centralized sports book.
I think I know how they will earn. When a user create an event then people will bet on it and then when a person lose the bet then they will take an amount of it. I really don't know about it if how much percentage of the amount they will get to earn from bets that are losing and then rest will be rewarded to the winners. In my opinion, it's much the same as the other sportbook but the difference is that the events are decided by users in the site. Not 100% sure so it's better that the op should clarify this question.
