Their concept looks very well. I think this could have a success and attract a lot of players and investors as well.
I like this concept too. 0% edge is possible if they will have a stabile income of new players and tokens price will increase. The first problem will be that people need to understand this is possible, after it they will be one of the best. Nobody wants to pay extra fees and everybody wants to fair chance beat the casino.
Ofc the players will say that this model suits them, but who in the world operator will be willing to operate such a casino on a large scale?
Now the next level of so called "attracting people" and new members will be having house edge in "negative". That might gain a lot of traction, but again, who will run this? You ? Me?
