BTW, my sponsor joined under Veronika Česalová, the owner of biggest PTC/Online earning web pages in CZ/SK. I am really not worring about referrals at all 
For you it is easy to have referrals, but for many people having referrals is a real problem.
The problem with this type of investment is that you depend a lot on the goodwill of other people (referrals) and the goodwill of the program managers.
Many people register at these Matrix sites, pay the membership fee and can not get referrals and the money ends up with the administrator
That's why I said that these matrix sites are only profitable for the creators of the site
