I made no specific claim about "crypto" one way or the other. My point is that to decide if some activity is legal, or moral, etc., you have to look at what is actually done.

It's not enough to look at whether the day-to-day work "feels like a normal job", or "looks like a normal job" from the outside. You can have a highly respectable job while interacting with people who all look like stereotypical movie mobsters (e.g. prison social worker). You can also sit in a respectable office all day wearing a nice suit while committing genocide.
