For me, it sounds like bait, events like this could be easily rigged, they could create an account on their own casino and claim the 1st 2nd and 3rd prize, and people will not be able to prove it was rigged. And that's a problem because this kind of promotion can hurt the casino's trust.
I don't think this promo is real, to be honest is just a nasty move.
I wonder when will the decentralized method of choosing will be applicable on casino lottery considering there’s a blockchain tool that can be use on this kind of promotion like what being use on forum game and rounds developed by @bitmover.
Maybe @Upgrade00 can suggest @bitmover tool to the team?
