Is there a referral limit or I can refer as much as I want then all the bonuses will be attributed to me? I haven't read regarding limits on referral in the whitepaper.
It looks like there's none, you may refer all the people you want. I think the only limit they have when it comes on referral is you can only earn a portion (1%) of the payment that will be made by the referral of the 5th person in your downline.
