Steem-engine makes forking out stinc a real possibility, once they are ready to spin up their own consensus witnesses.
The rose colored stinc glasses are getting handed out to fewer and fewer newbs.
The old users have turned on stinc in increasing numbers.
I think steem will be fine once they shame/downvote the abusers from the pool.
That may take a couple years as they gave themselves enormous sums of stake in the ninjamine, but the trend has already begun.
