Alright guys, I’ll try to be clear as possible.
I decided to give this a try and bought traffic pack+high quality upgrade in hitleap (around 40€ in total).
I did everything as author was said and got 1.6K of hits in very first hour or two.
But in the short-link service for some reason I saw 2K of hits and only 0.06$
After 2 more hours I had 3K of hits and 0.09$.
After one more hour my account was blocked from short-link service.
I contacted the hitleap administration for refund (as they provide that option) and they kindly accept my request. So I didn't really lost anything.
I’ve used only first method, maybe second one is working. Based on experience that I get I strongly do not recommend to spend your time on that one.
