By simple supply and demand economic principles, I think the price of HIVE is under pressure from this inflation of the supply. Your last graphic shows most of the new supply coming from HBD to HIVE conversions, but in the middle we see Author rewards which was 500K in August.
Let's BURN HIVE!
I wanted to so something about inflation so I went to https://peakd.com/me/referrals and set @null as a 5% beneficiary of my author rewards. Sure it is a small amount but at least I can say I am doing something instead of complaining about it or hoping someone else will do something about it! :)
