I only bet on regulated sites. You can make thousands a year in the VIP programs, especially if you're hedging the free bets and promotions.
That's a lot of free money and privileges if you're a VIP and of course it's good to take advantage of this.
I prefer a site to have a VIP feature because once there's a big player in the site you can at least have the assurance that the site is ok and the site will continue to grow more because of the number of their gamblers and the volume of money coming in on the site. Most of the top site have their own VIP program, and that is their big difference to other site.
But to get free money and many other privileges, you have to wager a certain amount of money to get bonuses from the casino. This amount of money is more than that of ordinary members, which does not require them to risk too much money. That is why not many gamblers are able to achieve VIP membership because there is a larger amount of money to be able to achieve VIP. Besides that, there may be a longer time to become a VIP member, and it depends on how much money they use and how often they gamble. VIP membership at each of these casinos is clearly different from other casinos, but each casino provides attractive bonuses.
