Why? Because it's prob the easiest way to earn some btc here and there are many, I can't tell what campaign is the best, read the info and what are they looking for and demands and that's it. So far, I've earned about 110e with campaigns here, and Im here for about 4 months now (wasnt a part of any campaign over the last month). So I would def recomend a campaign to you. The one I joined looks promising.
