1. Definitely not. But I think it's a lot better for streamers and casinos to put it in at least just for most people, who are not aware of it, that they aren't using their own money and that's why they can make those reckless decisions that they do in stream. I don't think anything is honestly lost there imo.
2. Transparency is definitely a must, why not? I mean it's something like a marketing as well or the casino if they were able to reveal that they were transparent as much as possible. Nothing lost is there imo and would probably be better for the long term
3. No not really. At the end of the day it's money that came from the casino imo.
4. Naturally the 1st one lol. Some streamers can and are able to hide and play their emotions perfectly but most of them can't, they're much better off just being transparent with how they play so that it's a lot more relatable to their audience. Building a sort of rapport between the user is more effective after all imo.
