As a gambling site it is always important to keep deploying the best methods to attracts people who gambling, and of course every gambling site has their sets of rules and regulation that governs them but that doesn't mean that gamblers aren't that permitted to have those choices while gambling. When gamblers do explore those things in a casino and they understood that such gambling site are more friendly they wouldn't mind putting their efforts over there or start using that site gambling.
You're right, there are things that attracts to some gambling sites, like that's minimum deposit and minimum withdrawal, how fast the site can be accessible too, there are some gambling sites that takes time to load, varieties of different game apart from casino games, there are some gambling sites that doesn't have sports book, it also a problem I know that they might have their own reason for doing that but this can also make some gamblers to stay away from such gambling site, before any rules and regulations will made by gambling firms, I believe they consider many things, let not forget that those are peoples business, so strategically put up rules that favours them the more without minding anything, although am not saying that they are right always but just that they put up all those stuffs to safeguard their business that's just it.
Yeah
that is true though but most times when gambling site are too strict in their rules and they are not that flexible it would definitely affect gamblers therefore, they locates those site that are much flexible while using their services. And again, just as you said varieties of games and also listen to community demands could also boost the casino so faster and growing exponentially.
