It was only a handful of engineers who "created the space" to begin with, so even though there isn't much overlap, it's pretty much always been a community made up of shady folks, it's only that the fraudsters have become less technically sophisticated and more brazen as activity has increased and the blockchain community has grown and continued to radiate cosmic rays of hype.
> always been a community made up of shady folks That's not fair. Shady folks are just getting more publicity. Noone talks about people who created stuff that works and doesn't scam people. And there's a lot of such stuff. This space is growing because of such people, despite the shady folks.
