The live esports betting caught my attention since I appreciate following and listening to tips from other bettors, but I don't think I would be able to watch the streams as much since I rarely tune in to kick streams.
If there's a giveaway, people will surely tune in. I doubt there will be many viewers from the forum because gambling streams don't usually last that long.
AFAIK, twitch is kind of difficult with these gambling related contents but you can probably also stream there at the same time.
It's possible if he's only doing the esports betting part, but I think he's better off sticking to kick if he's going to stream both casino games and sports betting.
