To make the devils advocate
Low barrier of entry and even lower cap of profits. Even if someone is a top witness, top author and has a dhf proposal passed maybe they can make at current prices what? 150 USD ? The diminishing user base suggests this number will only continue to go down.
On the other hand there are plenty of YouTubers making ten times that with much less effort. And overall, I bet there are way more monetized YouTube users than the current user number of hive. So, in a way even the main argument of "lower entry" for hive is problematic.
