If a client executes a trade, 80% of that profit goes to the client while 20% to Koinexpert. This 20% is the standard Koinexpert service fee.
However, in the case of the client being referred by someone, Koinexpert only maintains 16% of the profit while the remaining 4% is allocated between those who referred the client. The 4% is further divided with 50% of the referral fee being allocated to the direct referrer and the remainder is shared amongst up to 4 additional referrers, should there be that many that referred the client and their referrers.
We recommend reading through the "Referral Agreement", which explains this in much more detail. Click here for more information on the Referral Agreement.
