One real problem is am not a great author, thus I power down every week; however I love Steemit so i keep my steem active and do not sell it off.
But for others who hold a lot of steem or are not committed presenters or just lucky enough to gain some platform rewards or simply unable to Steemit they will always be selling.
Over time some things will balance out, however this is cryptocurrency so nothing will ever stabilize; wild swings are normal with bitcoin and other internet monies.
To expect steem to ever gain anything like a predictable price history is about the same as wishing the government would cancel income taxation. this means I might be a nice wish and is likely to happen just after cancer is cured and peace on Earth . . .
Maybe when aliens land and conquer the world their first act for humanity will to mandate a stable steem price point ; )
Thank you for being a miner ! ! ! : )
