Very interesting, for me that I am new and I do not understand very well this system has cost me to have some significant gain apart from my initial presentation, my rewards have been on the ground, and that I do not expect so much, because in a country like Venezuela with 4 or 5 $$$ are enough to help you half a month, however I want, anxious, know how to improve, for me any tool that helps me to get that income that I need is very helpful.
