Sadly, the "crypto space" was quickly invaded by hordes of people who never really cared about the technology itself, how it works and what it's actually useful for. (and what it's not useful for)
These people, who know nothing about it, and for years had dismissed it as a joke, suddenly began to talk about it very seriously as a very serious "investment" in self-proclaimed "expert" capacity.
You know the type of person I'm talking about! We've all seen them, and most of us can probably count one or two amongst our friends.
The potential for cool applications of blockchains is still there, but so far it seems to me cryptocurrency has mostly just been abused as a vehicle for crazy, baseless manias, and little to no meaningful application.
