how it works
say you have joined cashcrate but you are only making 20-50 dollars your first month. (realistic) your second month you decide you want to make more money, so you start referring people. now you have succesfully referred 10 people. and their each making 30 dollars a month. in all they are making 300 dollars a month. Since you referred them you get 20% of their earnings. if your referrals get a referral you make 10% from their referrals also!
(dont worry all the money they make they keep, cash crate gives you extra money for referring.)
Now that you have 10 referrals making 300 dollars a month you get an extra 60 dollars a month! now you do the math, you keep getting new referrals and your referrals get a referral you keep making more and more money every month!
