re: Twitch streamer, xQc signs 2 year deal for $100M

How in the heck does he make money playing video games? Who pays him? With what incentive? Do people really pay to watch him play? Are there really enough payers watching him play that it warrants $100 MM? This makes no sense like NIL. Who is benefiting off giving Angel Reese over $1 mil to where they get a return of greater than $1 mil? I can guarantee Angel Reese posting 5 posts on instagram of whatever brand is not going to get them near $1 mil from people seeing the brand and then going out buying it. How does someone who has $100 MM or $1 M smart enough to get that money but so stupid to blow it on these "performers"

Who is dumb enough to do all this? I need to see the math.
