Very interesting post indeed. I could imagine, for example, a scenario whereby financial transaction validation on the Steem blockchain is performed via SaaS (Steem as a Service). Steem could charge nominal fees to parties for large-scale volumes. Small players would essentially next to nothing (attractive selling point for on-boarding) as fee from the but players would cover costs and generate sustainable profits.

If can demonstrate it ability to scale, ensure secure transaction provide rock solid reliability, then Metalpay could serve as a good test case for Steem. Success could attract other key players with the industry and help the drive towards getting reliable crypto to the masses.
