A great post @preparedwombat.
This is exactly what the numbers I run each month state. The distribution is flattening out as time goes by. Collectively, the smaller accounts are gaining much more power.
Going back 6 months or a year really shows this. Give it another year with an increased sign up and, hopefully, participation rate, and we will see these numbers move even further.
The bottom line is there is not enough STEEM to go around meaning that it will go up in price since demand is there.
