i think dogecoin and the likes are running on sentiments of their support community, these guys keeps developing and updating but I dont know how long they will keep that up? I guess most of them will die off in the long run but those with working services will eventually be the only ones left.
I am currently writing a contest entry for such platform, it has been in existence for 2 years with about 500k users, they need the ICO money to scale and also make information provided by their travel site more trustworthy. Such coins are not subjected to investors emotions or market fluctuation (in my opinion) but on the growth of the business behind it. They are less likely to disappear.
Steemit, to me is also a good example although they would find a way to monetize the site (i mean get money from third parties, not us).
I agree that most companies will die over the long run. Regarding Steemit - it will be interesting to see how it evolves over time. It could end up being like facebook - starts out as a free service with no advertising, but then eventually they added adverts to the site to generate revenue. I believe steemit is working on smart media tokens (though I haven't followed that progression). If this ends up being the case,it will change things and possibly add to its sustainability.
it will be great to see how all that plays out. I do not know about the smart media token but if they end up putting ads, they will pay holders dividends (hopefully).
Yeah i guess we will see. It is interesting
