Most of the people who invest in the crypto market are those with stable jobs.
I am in this category, and I earn way more money with my real job than anything in crypto. Bitcoin is just a neat hobby to me, and the signature campaign stuff is just gravy on top of the beautiful Thanksgiving turkey that is bitcointalk.
If I lived in the Philippines or Cambodia or some such place, I'd probably be able to support myself and buy a new house. Except then I'd likely be a 3rd world country shitposter, because I have yet to see a member from one of those places be a fully contributing member of bitcointalk. Where I live, the cost of living is extremely high and thus the campaign earnings pale in comparison to what I have to spend--but it does make a difference, I have to say. And I can see why so many shitposters from these backward countries flock here to do what they do. Fortunately a lot of them not only don't get accepted, but they get blacklisted as well.
