An Affiliate can receive a bonus only for those Referrals who have fulfilled all the conditions and have not been disqualified in accordance with the Referral program rules.
You can receive the bonus only for the first 5 Referrals who have successfully fulfilled the conditions. For the rest of the Referrals, an Affiliate doesn’t receive a bonus.
Let's say you've invited 5 Referrals using a referral link. All of them have successfully fulfilled all the necessary conditions, but one of them was disqualified in accordance with the Referral Program rules.
Since you can receive $15 only for the first 5 Referrals that met all the conditions, you will get $15 for 4 Referrals and $0 for the last Referral (disqualified one).
Then 2 more Referrals registered an FBS CopyTrade account using your referral link. This way, you will get $15 for one Referral and $0 for the last (the 6th one).
In total, you can receive up to $75 for 5 Referrals.
