How does it make money?
Well, when people make deposits and gamble on your site, they will 100% lose if they continue playing. The adage "The house always wins" is true in its entirety due to something called the "House Edge" that gives the casino a statistical advantage.
This is too good to be true, 100% in favor to the casino will not attract gambler and that could result to a big loss for someone who are planning to deal with this kind of scheme. Casinos should be fair because this is how it works and most of the top site right now are fair enough not to take advantage of any gambler. If you are going to introduce any site here, i will also not support it because your intentions are not good, that's too much greed and not a business anymore.
