Rented referrals (RRs) are not profitable for free members.
Standard members earn 20% of click value
20% x $0.005 = $0.001 per click from Standard Ads
That means if your RR clicks 4 ads daily for 30 days then you will earn:
$0.001 x 4 x 30 = $0.12
But, take it in mind that it is hard to get an average of 4 from RRs.
