Managing a casino is a serious business. Most people think it as a passive income where you just set up your money printer and forget but it is nowhere close.
It is really nowhere close to that if an operator thinks that way he will find himself eaten by the competitor, for them to earn money they need to spend money and a lot of effort, yea there is money to be made for operator but with so many gambling sites vying for the big slice of the market, they are not resting they set up massive promotion and a lot of giveaways to keep the gambling site always in the limelight.
