Probably not the best, but I use adfun on my iOS. Use a different account on each one and send the points you earn to one account as a gift. You can gift points.
Tell me why does it take so long to make money on adfun? or am i missing something? i have 8,852 points at the moment and it took forever to get those points using 4 or 5 devices i finally got fed up and stop using adfun months ago. I would turn them on channel 3 and 5 and let them run
