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.
Yes! In the whitepaper, its indicated there that you can refer up to 5th level. But on the excess of 5, its not mentioned if there's additional bonus or incentives you will get.
