I agree with a lot of the reasons you give why the price of Steem is going down more compared to other cryptocurrencies, but isn't there way more selling pressure with POW (Bitcoin) than with DPOS (Steem)?
With POW, there is always an incentive to put in more hashing power as long as it pays for the electricity. This means that the price of mining 1 BTC should ultimately correlate with the price of 1 BTC. Of course, electricity prices are not the same everywhere, but it would still create incentives for someone to make a profit somewhere.
With DPOS, you don't have that amount of selling pressure. You have the monetary inflation which goes to content creators, curators, witnesses, (worker proposal). And you might have (big) stakeholder selling their stake for whatever reason that could be, one of them certainly is paying for development on the Steem blockchain.
You had it right with your article named 'The Steem Name Is Mud Within The Industry'. Steem(it) is perceived as having failed. It's the "Friendster" or "Myspace" of Web 3.0 Social media in their opinion.
There is only one way out IMO and that is massive REBRANDING. And I think for it to be successful, it could only come from Steemit Inc.. Not too much is needed, but Steemit.com needs to be retired and replaced with something else.
