Understanding of what? The technical side? It seems HN seems hell bent over discussing all the scams and get-rich schemes, and completely discards the cool technology and things that it enables (see https://news.ycombinator.com/item?id=31996612 again, as stated before).

Yep, exactly as I stated, focus on all the scams. That has absolutely nothing to do with technical expertise you know.
Edit: crypto is a cool technology, and has at least 1 use-case (see link above). Try to argue with that instead of sidetracking the discussion towards the scams and get-rich-quick schemes.
