Well, some say that you need three active refferals, before its better to upgrade. This is because you are only guaranteed 4 one cent ads every day. But if you are active, you will make more like 7-8 cents everyday, because of the 15 sec and 3 sec ads. Im not sure, but I believe its better to go premium, no matter what, if you are active.
However, you should try getting some refferals! Its hard, but its worth it! I only have one active refferals, but I make 3-5 cents everyday for just one refferal! My income (not including tasks and clixgrid) is boosted with about 60%, just for one single refferal. Imagine what alot of active refferals what result in.
