Everyone I know who is into this is very strongly into it, and they can never really explain why. Lots of non-specific sentiments emerge, and rather quickly, but no real this-changes-things-because-of-X details or explanation about anything. It's the same pattern I've seen from people who believe in psychic readings and Tarot cards, except those two groups can get very specific, it's just about imaginary things.
Age is a superpower. I have a few decades behind me. You see patterns in behavior, because people are not snowflakes, and incoming generations make the same mistakes the outgoing generations have made, and must learn the same lessons previous generations have learned. This generation is trying the things that the other generations already tried, etc. Some things change, but the fundamental things people try to do with their lives, those don't really change much generation to generation.
Experience is a good teacher. Now, maybe I'm wrong about cryptocurrency, I'll gladly admit that. And I would counter by saying that "I'm seeing the same broad strokes I've seen previously, with different names."
From what I know this has mostly been described in dystopian sci-fi before, not really tried in earnest.
I'm curious about what you've picked up as well. Like people not being able to explain why they're into it. Could you elaborate on those things a little bit?
That's my (of course limited) experience with cryptocurrency advocates.
Your whole comment sounds like confirmation bias to me. You don't like crypto, therefore all the new terms you've never heard of must be bad stuff, everyone is out to scam people and crypto isn't "on the level".
