Op is also a lier you don't win that much with that number of referrals
It's easy to calculate.
Op said that:
1. he has 40 referrals
2. he "made 0.00077324 BTC in a month".
As soon as owner of 40 referrals receive 13.5% of their earnings, that mean that his referrals earned 0.00572770 BTC in a month together. Or 0.00014319 per referral. 477 satoshi daily.
It is possible. But not on qoinpro:)
