A casino is a for-profit comoany and they have to make a pre-determined income in order to remain profitable and don't find themselves forced to shut down their doors. The percentage of profit a casino has to make does not differ much from one casino to another, it's almost the same.
So, if a casino is offering huge rewards and/or bonuses, be sure that they will componsate somehow (ie. higher wagering requirements, higher house edge..) and vice versa. It's up to the player which plan suits him more but the end result is always the same.
They do only differ on very small gaps but we know that some gamblers are really that keen even into those small differences thats why they do make transfers and choose another place but in overall
they are really been hooked off due to perks and bonuses which we know that wager requirements are into those levels which are almost impossible for someone to achieve thats why we do end up
losing in the end without able to reach out those threshold which its not surprise for any business.They wont really be setting up things that they would be putting themselves into disadvantage
which is understandable.
