It would be nice to have a table or a list where we see how much we earn from our referrals.
I get about 20% from my referrals, am I right? this is true for level 2, level 3 until level 5?
Yes it would be nice to have such statistics.
20% you get only from 2 and 3 levels. The 4th level gives you 15% and 5th level 10%. Check their website for further description.
For the 3d level you get 20% only if you have at least 10 nodes at the 2nd level, otherwise you get 10%. The same restrictions apply to the 4th level.
Please also note, you always get 90% from your own computers, rigs etc. and 2% from your referrals having such heavy equipment.
