you are right. If you have active many referrals in this case it is profitable but if you do not have it it is a waste of time. I was reading emails for 1 month and my income was $ 0.12. Of course I did not lose much time but this is a very small incomeI have never tried it, in fact this is my first time hearing about it, but I will give it a trial despite the fact that its payment rates is too low, I will try as much as I can do visit the site.
