After registering in the program each user receives a unique link which is used for inviting users to the system. Based on these unique links, the system records the referral connections on who invited whom to calculate and distribute the referral rewards generated by the users when they pay for services. There are 10 levels in the system, which means that the referral connections go down to 10th level, where the level determines the percentage of rewards for each referral level: the further down in the referral structure, the lower the rewards percentage, but more people due to multi-level marketing effect. (See Example below)
Example: Referral structure
A user Mike invites Alice, then Alice invites Peter and Peter invites Bob. So: Alice will be registered as a direct referral to Mike or his 1st-level referral, and Peter will be registered as a 2nd-level referral to Mike, while Bob will be a 3rd-level referral to Mike. Such a structure continues all the way down to the 10th level when more users join and continue building the network.
