If Servicenodes were available, I'm sure a lot of people around here would set-up a fair few and donate most of their profits (after hosting costs).

You would probably see donations in the region of $3,000 to $7,000 / month, mainly because it would end up being a self funding mechanism where more development would equal higher price, would generate higher value donations, would generate more Bittrex activity.

Servicenodes would become the main patrons.
