It sounds like you're talking about domestic mass surveillance but there's no way the US would use such a dangerous tool just to find random cryptocurrency geeks.
NSA employees used PRISM data to spy on romantic interests, I don't see why this is any more dangerous
And AFAIK those employees were fired because that is against NSA policy and tons of laws.
Why weren't there controls in place to prevent them looking at it in the first place? And that's assuming all the ones who did so were actually caught
I think OP was being sarcastic....
Your comment highlighted a point I consider valid, though likely not the one you intended; I’ve added a footnote about non-US countries, as many of them have no such reservations about wiretapping network traffic to catch financial criminals.
