From this post alone you have $79 listed reward. As much as a quarter of that goes to curators, that leaves about $59, and then half of that goes into steem power. This single post therefore pays you 30 SBD, which is about $90 USD.

Steemfiles, which is for digital downloads for a fee, provides a way to monetize content. The ideas expressed here might also help me improve Steemfiles. I would love to run my own RPC node for Steemfiles instead of having to rely always on others for that.
