So much of what we see in all of crypto is colored with a perception easy money - a way to get rich quick - and that extends to HIVE as well: people think they will miraculously get rich by blogging (of course, there is nothing new about that either as people have begun traditional blogging with visions of gaining thousands of followers for ages now). PREDICTION: someday the vast majority will just comment and upvote knowing they will never be 'star' bloggers, and they will do so because they have HIVE, not the other way around. They won’t be buying HIVE to blog, rather they will blog because that is a nice “extra” that comes with the core attraction which will always be the underlying cryptocurrency. Remember, bottom line, blogging/commenting/curating (the pay is the same now) is nothing more than staking. People don’t buy crypto so they can stake. They stake because they have bought, and they buy the underlying currency for the reasons they buy any cryptocurrency: trustless and secure / widely distributed, and decentralized.
In my opinion, the core you refer to will be the creators, the hundreds of millions of other users will be those hodlers just mentioned above who read, comment, upvote, participate and receive their, albeit small, but nonetheless proportionate, share of the rewards too.
In-so-far as ETH goes, I'll be brief: birds of a feather fly together. Where in crypto have we seen more scams? Where have we seen more hacks? More incompetence? There're doomed. The ultimate ETH killer is ETH.
And, remember, HIVE will end up doing a lot more than it was designed to do. :-)
