Anyway, I really wasn't interested in these kind of targets or whatever, that's why I stayed away. These kind of promos only try to keep you wagering to achieve whatever, that's not how I roll.
Have you checked their VIP program details? The total rank up bonus for $1 million wager is going to be more than the amount which they have offered to you. You will reach platinum 2 rank with $1 million wager. The total rank up bonus amount will be $1960 if you start from the beginning. While they have offered you $1750 for $1 million wager
