OK, got vouch copy from OP. I'll give fairly review.

Method is easy to understand, and i tested since last night OP give his method to me but you need to patience.

So far his method is working well, but there are only few case method failed to working.

Well , because this is gambling, there are always probability you'll lose.
if you already get some profit , just cashout it.

Good luck with your sales OP
