It’s nice to see numbers to what I have assumed for a while now. Increased price and less people using their full voting power are only ways.
I don’t think reward pool will increase at a fast enough rate. Even more so if bigger and bigger follows come over here from places like YouTube, Instagram and whatever else. I’m sure a year from now we all will have been grateful at how easy it was just to earn a single Steem. It will be interesting to see at what point do they increase the visible decimal places in our wallets as a higher Steem price will warrant that.
Some of the bigger holding of SP seem to get this and don't vote to their max potential. Or they least delegate it off to try and get it to the causes they wish to support.
Somewhere between all the vote selling and delegation selling there will have to be a balance. If large invests truly want their holding to grow in value they would be better off looking at long term increase in price over short term of just selling their vote to highest bidder no matter what it is.
