That's interesting! I remember the good old steemit and their stake that it was going down constantly as time was passing by... With lower inflation and curation rewards, it has no sense that whales gain more than others, but if data says so, then it's true :)
Btw... that's even worse news then... lol... HIVE sucks in decentralization big time... :(
That's the problem... protectionism in a small pond.
