I wanna proof my theory

Buying 100 Case
Today i just bought 100 case at 3.98 which means it cost 398gold for 100 case.

What i get?
I get a piece of shit! Not even one purple item f**k !!!

And i dismantle all of that shit then get 1.5k scraps

I sold that all my scrap and get 360 gold
WHICH MEAN 398-360 = -38gold
F**k !!!
I will open another 100 case if this article get 30 like !!!
OR SHOULD I STOP GAMBLING?
