One more thing that i can`t understand. As for me it is just a waste of time. I can`t say nothing bad about these people - they find a way of easy getting money playing for fun. And i can understand when someone watching it for 15-30 minutes for relax. But lots of spectators watching it all day long... I can`t understand it.
That's the entertainment industry nowadays. Many young people don't watch TV. They watch a guy or girl doing stuff on Twitch or Youtube.
Maybe this creates some kind of artificial emotional connection. Maybe it's the chat feature on Twitch and the comment feature on Youtube, which creates a sense of interaction and giving feedback.
Anyway, OP has compiled a nice list of gambling streamers, but I don't think that this list would be useful to anyone in the gambling forum.
Maybe a bunch of crypto casino owners can use this list to find and hire some influencer to promote their casino, but I don't think that this would work, since most crypto casinos don't have a gambling license in the USA.
