The basical referrer system gives you 100% of what your referral earn.
But this is only the seeable part of the iceberg.
You can earn much more:
Each time your referrals earn 5000 satoshi you earn for this 500 satoshi.
Have you claimed the 400 satoshi?
The more you claim if you are my referral...the more I can offert you 5000 satoshi...thinks about.
