Is it easy for lets say the bottom and mid hive holders to get a post to trending?
Why should it be easy? Is it easy to get a starting spot for the Lakers or Real Madrid? Could you get a starting spot for your local city team?
The next two on the list have 700 HP and 129 HP
That is the top 15 in Trending. Also, most people don't use Trending, they use communities to find their content these days.
You should have a look a bit deeper.
This is way off my point, the point is, the middle and lower holders barely pushes a post to the top, and worse they don't curate enough.
Making content rewarding centralized to only whales and curation guilds.
None of this depends on Hive power.

As said, you are very narrowly focused and no matter what I say to illustrate, you stay narrow. You are sounding very ignorant.
