It happens with technology sometimes, but all time the with finance. Having worked in hedge funds most of my career (as an engineer but I see enough of the business side) it's hilarious how clueless but confident people on HN are about anything that touches finance, trading, stocks, crypto, etc. Nothing wrong with being clueless, but the hilarious part is the confidence of the posters about what they are writing, which they probably got from Medium. If you don't know better you'd think they know what they're talking about.
