" (Steem tokens) have no place to go except up"
Technically speaking, as an infinitely inflationary currency, they have nowhere to go but down in the long term.
"The number of accounts have now probably about doubled"
Too bad we retain almost none of them due to our toxic culture and flagging SJWs.

"I don't see why a lot of people would suddenly lose interest in something as great as Steemit!"
Incompetent company, focus on SMTs, toxic culture, SJWs/flag wars, open hatred for investors and success stories...
I was just offering my opinions.
After getting into Steemit a little further since my original comment, I see a few reasons why Steemit could fail. You touched on one ("Too bad we retain almost none of them due to our toxic culture and flagging SJWs.".)
Also, the fact that many writers seem to post only to make money, with some having exactly zero interaction with those that comment on their posts, and still others never giving an upvote to worthwhile comments, those that offer something more than, "Good Post," will also turn people away from bothering to participate. I thought rewarding others was at the heart of this financial Utopia?
Steemit could eventually become a place for those holding substantial Steem in order to accumulate more, but once those having little Steem start to give up and exit in droves, it'll be a race to dump what's left and exit with maximum gains. Utopia destroyed.
At one time I was about to invest cash into Steem, but I don't see that happening now. Unfortunately, I can easily see it going the way of the 'Pet Rock.' I wish that wasn't my opinion.
