Before this grid there were 3 grids where I tested the pops and they failed to turn a profit. My friend advised adsterra which I have been using for a long time. I googled 50$ coupon for $200 and more. I have refilled my account 250$, I adjusted my tracker, companies and go) Setting up easy, plus-minus, as in other networks, but there are a couple of cool chips, this increase or decrease the bid on individual sites, I really liked it, you can immediately increase the price at sites where the conversion is burning or vice versa lower where necessary. Moderation companies in general pleased within an hour approve. I liked the traffic, it was of high quality, I received 250$ in addition to blacklisting and got 36$ in profit, if I use coupon 86$. Sometimes it disappears at me, although it happens in other grids, some large advertising comes, but it was not often. I am satisfied with the grid so far, I will test it.
