I can imagine what will happen here ... everyone will pile in the second the round opens and after that nobody will put in any more money for the rest of the round.
Actually not I have a unique idea which sounds really fun and has never been implemented before.
The operator can easily write some doo dad (technical term) to ensure that the bulk of the early money is his. How do you stop that?
In that case there in no way to prevent this the operator and gamblers takes the same risk and has the same chance of having most of the funds on the top.
Or they play it out rake in a high amount of fees, an unknown amount of scammed joins (from payouts to self) and dont even have to hide. Sounds like the perfect crime.
I realized that I will make far more in along run from fees than I will earn from scaming and running with the coins so I am not afraid to do all the business with the most trusted escrow here. Would you still add negative trust for me?
