ZioMio:The money you earn from moving up in tiers is already awarded in credits.
Please excuse me, that's no money, it's credits. The only real world money here is used at "buy WGT credits", it disappears in our host's pockets.
Unfortunately, the $$ "earnings" displays contradict their T&Cs and create the illusion of real money retrieval. Your post shows that the illusion works. We can smell the money but we'll never get it - just like strawberry yoghurt without any fruit in it, only flavour.
