yes, in earn.bz, whatever the type of membership, the cost of renting referral is $0.3/ref. so is it expensive?
  1. For being a standard member you will get $0.002 each your referral clicked. So for 1 rent refferal a month you will get maksimum profit = $0.002*4*30 = $0.24. But you must spend $0.3 each rent ref and that is a minus. in conclusion, for being standard member DON"T RENT a REFERRAL
  2. For being a silver member, you will Earn 50% of what your referrals earn. is it $0.005? no, it's a tricky one, in fact you will earn $0.004 (50% of $0.008) of what your referrals earn. Then for 1 rent refferal a month you will earn maksimum profit = $0.004*4*30 = $0.48. Yup, for being a silver member, your renting referrals become profit. so that, if you wanna rent a ref, start upgrading first.
  3. How about being a golden member? you will earn 100% of what your referrals earn so that means you will get $0.008 from each your referral clicked. then your maksimum profit for a month each referral is = $0.008*4*30 = $0.96 and you just paid $0.3 each rent ref? is good? nope, it's a best decision.
with that basic calculation, we know that being a member at earn.bz is more profitable if you are upgraded member. are you gonna upgrade your account or not? it's your decision to make.
