I think if the deposit method to increase the VIP level will be easy for gamblers to get.
For example, they make a large deposit and a few days later they withdraw the deposit capital and repeat the same thing. Is that considered valid to push our VIP up.
Well for a start, it's not going to be that easy, once you have a deposit, you maybe be required to first wager it before you think about withdrawing. Chances of losing a bet are also possible.
I also don't really understand the deposit strategy to reach a higher VIP. Because I often play at stake, the bets that are counted reach a higher VIP level, of course that makes sense and also requires a lot of processes to reach a higher rank.
Maybe that's their business model that seems to work for them. At the end of the day, the casino is just looking for all ways of making money. Larger deposits mean larger bets and possibly good making opportunities.
