As long as I know the reward for leveling up to Platinum 5 is $3,200 and usually there are also 2 other bonuses. They are recent gameplay bonus and reload bonus, these 2 other bonuses will be based on your recent activity (maybe the last 7 days activity). What I like with your strategy is that you did not force yourself to level up by deposit and wager although you are closed enough to the next level. It shows your patience, because I believe most other players will try to do it quicker by depositing and risking few hundreds dollar to get the $3.2k but you do it differently. Well, once you get this month monthly bonus, I think you should start do spam bets on dice with high odds such as 1.1 or below to wager the remaining requirement amount to level up. Good luck mate.
