I was thinking of wagering for the sole purpose of reaching Platinum 1 but now I am in no rush lol.
Advice for you.
Just do these, at the time your waggeing around 10% left. Focused on the waggering is fine but not all of them, the rest just do at usuall (betting). Meanwhile for chasing VIP you can do these at the time 10% left for under Platinum Rank.
Meanwhile Platinum I-III you can focused at the time 5% left.
