I would say that paying $100 or $200 to promote your post, is on the one hand admirable as the amount you pay is 'burned SBD' which is a benefit for the whole of Steemit...on the other hand it is probably expecting a payout from the reward pool of many times the amount paid, that in itself suggests a little (or a lot depending upon your viewpoint) of greediness.

Is expecting a payout from the rewards pool of at least $100/$200 or more for a single promoted post, greedy or not?
