Guys, my advice! Tested different networks, income was plus - minus equal, but I was tempted by popularized monetization of trafficback + redemption of ios in zpush - I have mobiles mostly, and apple traff is even more than half. Income went up significantly, about 1.5 times, and the base has not even gained yet. A little later I want to mix it - to leave the ios in zpush, the rest of the redemption in another network - but now I am completely satisfied with the income, I will not do it yet.
Out of the inconveniences I can note inability to withdraw to PayPal, otherwise everything is ok
