I dont mean insurance in a literal sense, but in a practical sense. The only negative I am hearing about steemit is that the whales have too much power, but as I write, this power is needed. So, like in the real world, the millionaires all do charity work. That way the masses accept them as they directly or indirectly benefit from the massively wealthy.
Already steemit is close to a viral propagation and explosion, so if the retention rate issue is solved, then that "insures" its success based on the fact that people like money. So if to choose between not getting paid and posting on facebook or posting on steemit and getting paid, then most will choose the latter. All that is needed is for there to be no big negative, like envy.
but if the entire system is tilted so that the rich upvote for the less rich, all the way down the line, the envy part is for the most part squelched.
not sure why you downvoted my post??? [he un-downvoted!]
