This dude has 350K viewers on a Friday afternoon. That is absolutely insane. I checked it out to see what this streamer university stuff is and I think i'm a bit too old for it. But still, bruh... just to put this shit into perspective. 125K subs, he gets minimum $3 per sub. With his contract, i'm sure it's more than that. That's $375K. Ad revenue is hard as hell to calculate so i'll leave that out. Have to leave all these donations he's getting out too, and there are a shitload of em.
Then, his team cuts these same videos up and uploads them to his youtube and his social media. I wouldn't be surprised if dude is clearing $600K a month before his expenses. That's not even including sponsorships, commercials, etc. Dude found a lane and perfected the hell out of it.
