Gachapon Boxes: could it be that..

Ive sold well over 800 keys so far and its all random. Ive seen ppl get really lucky and VERY unlucky. Ive been selling since day 1 and there has been no 'time' when ppl were luckier than other 'times' as far as I can see.

You spend way too much money on maplestory.
800 keys sold = 1,440,000 nx cash = 1440 dollars
Assuming you sold it for a 1k nx = 9m mesos rate
You've made about 7.2billion mesos

now my real question, was it worth it spending 1440 dollars for some virtual money?
