It's not worth going point by point when there's so many fundamental misconceptions. Best to reject the entire comment.

What HN needs is less engagement with useless, time consuming misinformation, and more outright rejection of it.

That may work if you're a known entity who is known to be an expert on the subject, but for an anonymous forum, just saying "you're wrong" without any explanation is stupid and useless.

No, This is incorrect

If you don’t go through it point by point and just reject the entire comment, then how is everyone else supposed to know that it’s misinformation? Right now it’s just your word that it’s incorrect. You have to back your claims up.

I usually don't comment at all on HN crypto threads, it's never been a productive use of time. I slipped on this one, totally on me.

The fact that you made a second comment, yet provided absolutely no refutations of any of the points in the original comment under discussion, suggests that you cannot refute their points.

Although, the phrase "What HN needs is less engagement with useless, time consuming misinformation, and more outright rejection of it." instead suggests that you are of the totalitarian nature that prefers to suppress dissenting thought entirely, so I'm not sure what to think.
