VIP rank is not an easy height to come by and you are right on the need to spend a lot of money in wagering before reaching that level, and if care is not taken, the gambler may become VIP when he/she has already lost interest due to the hustle in attaining that height.
-Casinos are well aware of all the benefits that come with the various ranks and just like bonuses tmcasino already have an established system that places them on the winning at all time.
That's not really true, a lot depends on your game session. There is a chance that with a deposit of only $1,000 a player can make a volume of bets 50-100k dollars?
Here's an example of my stats on the VIP program (BetFury):
So anything is possible
But not everyone is willing to risk spending $1,000 straight away just to gamble. They prefer to deposit a certain amount of money and play gambling. If they lose, they may deposit money again or not return it for a few days. That is why getting to the VIP level can vary from one person to another because not everyone has a lot of money to gamble with.
For the little gambler, reaching the VIP level might just be his dream and he won't know when it will be. And it's better for him to play as it is by not chasing anything because later, they will also reach that VIP level one day.
