Yeah when they released it first it was like 0.5 per day and they have been upping it fairly regularly. I think they are reigning it back in a bit now though. I got like 20 a few days ago but last couple of days has been around 10.

I had exactly the same thoughts as you that it's a lot to be just giving away so easily. There is around 80,000 "mining" at a time so that's nearly a million ETN per day. They say they are giving away all the un-bought ICO coins which I guess is in the billions.
