This will probably be perceived as arrogant, but I really don't even have to do any math, or any investigating to know this to be false. With the amount of vote selling going on, it's simply not even a possibility that the distribution is leveling. Whichever witness wrote that, is most likely cherry picking stats, or perhaps simply overlooking other variables. For example, more accounts does not mean more Steemit users. Many of these early adopters have a great deal of accounts, some have openly admitted to having thousands. So, one cannot be sure that the small accounts which are getting more STEEM, are not simply swiss bank accounts of long time abusers.
