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.
yes., you can refer as much as you want bro., but about the bonuses that you will received, it is still a question. i think you will also get a bonus, but its not as much as the first or at level 5 bonus. but the important here is that you can get additional bonus if you can refer more.
