Right now, what is the expected rev of, say, 10000 NEM? I know that with POI the more you are active the better, but just to understand... is it me or it's very very low?
Also, the supernodes (that cost a bunch of money), are they giving like 2% of revs/year?
It's very, very low. If you buy 10,000 expecting to make a regular income you'll be disappointed for now. Many blocks are still empty. It will improve as more actual use arrives.
Supernodes share 140,000 XEM between them per day. It seems to average about 2-300 XEM per supernode per day depending on how many are active.
