Earlier quoted context omitted.
During a lunch the topic of cryptocurrencies came up and a co-worker of mine said he'd invested in IOTA and EOS (another nonsense coin). The thing is I think he's smart and a programmer with the head in the right place and has made a ton of very good decisions at work. So if you think these projects only attract idiots and fools you're wrong. Smart people can also be fooled.
Gullibility and analytical intelligence are not mutually exclusive.
A lot of these crypto companies frame themselves as liberators from the banks who don't want to give you a share of the pie and so on, targetting vulnerable people who seek opportunity. It's very cynical.
Another space where I have observed this is online education startups. Lots of "you don't need a degree", "the universities are just trying to keep you out", "we're bringing education to the masses" etc. Same sales pitch.
