upgrade to member premium or not?

It's not that hard to rent referrals after you upgrade. You just have to smart on choosing your renting time and of course you got to be really quick in renting. Trust me, a millisecond will count! I upgraded with only 30 rented refs and I was able to rent 100 packs of refs everytime my renting schedule hits up. But you may not end up like I do. I just want to tell you that it's really hard to rent but it's not totally impossible. And by the way, getting 500 refs before upgrade I think would give you massive loss since it's so hard to gain from renting refs if you're just a standard member. Plus considering the time it would take before you upgrade, it's 5 weeks. So 5 weeks of maintaining refs with high probability of losing is not good at all. shadow41
