But the system of casino users themselves who are given the opportunity to contribute to the casino's Bitcoins for a share/percentage of the profits is not new. I don't know if Crypto.Games continues to have it today, but users can deposit Bitcoin to the casino, and you can "invest" in the site by letting them use your coins as capital. BlackJack.fun currently has it now as a new feature. It's the same system, but without the token.
I guess it would be the same if tokens can be acquired only by purchasing them, in that case, it would be almost the same if you invest in casino bankroll directly with your coins or you have to buy tokens and stake those tokens. I say almost the same because it's not the same if you are staking Bitcoins or some new token, the level of risk is different.
But investing in casino bankroll or buying tokens for staking is one thing, earning by playing is something completely different. Basically, you can wager a lot even with a small bankroll, with a bigger bankroll you can wager even more. The point is that in dividend-based casinos there's a chance for you to get a bigger share of casino profit if you are focused on wagering. Of course, that comes with risk, what gambling actually is... but besides the possibility to make more tokens (and get higher daily payouts) simply by playing we also can enjoy and have fun playing our favorite gambling games.
