It's not even that crypto is bad, it's that it's not good. The user experience is bad universally. I say this as a tech person that didn't care about it as a technology and had to deal with it anyway and I can't stand it. The first crypto service to actually, God forbid, go study Stripe, Shopify, Google Pay, Apple Pay, please understand, actually understand how people pay for things and compete with their actual competitors in a real way, is going to steal the show I'm sure. Until then it's crypto scammers competing for crypto users and crypto dollars and again no normal people want to put up with this shit at all because it's a stupid game and we're just trying to buy things.

EDIT: I clicked on the PDF out of a sense of good faith interest and curiosity and I regret it. I hope you find something else to do.
