I agree that cryptocurrency has a ton of UX issues to work out in practice, but you don’t need the level of explanation in the top post in order to use it, so the issues mentioned aren’t relevant in practice, and aren’t a good example of “poor cryptocurrency UX for end users”.

What the redditor did was analogous to ignoring the exposed UI elements on a web page and instead opening up the console and calling the JavaScript functions directly. The average user doesn’t try to do that, and so any such failure is not an issue of the website “needing an advanced understanding”; simply following its UI elements is enough.

So it’s unfair to equate the understanding needed for the top explanation with the understanding needed to use a cryptocurrency app.
