@Gurgling no, actually, it's worse.
When they first started it, it was:
3x the original, double that offer, then 1.5x the most recent offer, 1.7x that, 2x that, 5x that, 7x that, 10x, 15x, 20x, 40x, 50x, 100x
So if the original was $50, it would've gone:
$50, $150, $225, $382.5, $765, $3 825, $26 775, $267 750, $4 160 250 (that's 20x).
100x is about 800 billion - so it's even more of an idiotic thing than you originally thought
