I'd love to see more discussions about "But where does the money come from?"
In July of 2016, I did a bitcoin pizza challenge contest to get more people thinking about this stuff. Many people spend their entire lives working a job to make money, but they've never stopped to think about what money actually is. Cryptocurrencies have come along and forced people to ask these questions, and I think that's a fabulous thing. So yeah, my question would be, "Where does the money for the Steemit rewards pool come from?"
(my perspective: investors have something to do with it and financial value can only be determined in the moment of transaction)
