How to win items in blackmarket

I made this video a couple days a ago and now I post it here..


Summary:
First buy crates (32k gp)
Put your arrow on spin button as accurate as possible when ever you spin
That's all.


Note:If you already won a permanent item u can't win another one with this metod.

i think this is bullshit. because its completely random.
my method was: looking at the time when some1 won sometin, like i got my xm8adv right on 00.00AM
