I have no idea how much he's actually earning, but clearly it's enough that he keeps doing it and not a whole lot else.
As far as how much can he be making? I know a fairly low level YT/Instagram "influencer" that makes 6 figures doing that. So, yeah, he could easily be making his living just putting out those BS videos. I don't think UTG is making that much, but maybe he doesn't need to. Beats me. I've only ever watched a couple of his videos, there was so much BS and misinformation in them I usually don't bother anymore. Wouldn't want him to get paid on my account.
