I don't think a real high-roller gambler would want to stream his gambling because if people knows he can afford to do that then he is putting his life in danger.
Not be so paranoid about security, but I remember seeing some videos or some clip online doing this and it doesn't matter to them so you can say it's okay for them.
Mentioning about a high roller gambler doing streams, well, they have their own security measurements of course, rich people wont just walking on unsafe place alone. Or living in a simple house without any kind of securirty knowing his making huge profits and do high rolls.
I'd like to believe that there are many fake streamers trying to manipulate the results, they are being paid by casinos to make it look like its easy to win in the casino they advertise, they are not spending their own money, why would they if they want the casino to look good they will strike a deal on the casino that they are going to promote.
That is casino streaming is a very popular advertising preferred by casinos because the audiences see the streamer's winnings and they are enticed to play in the casino, hoping to get the same results.
Would you mind giving examples of this fake streams that manipulate results? Seems a huge claim to be exact. If it's an advertisements that saying you can win $xxxx when playing or gambling then it's bullshit and that's fake, gambling is not designed to make someone rich unless you're already rich. But if it's just a stream review to check and experience the website of course the gambling will provide the streamer's account balance to play for free, then i guess that's okay, as long there's no too good to be true offers there.
