About streamers, it is indeed a profitable venture if the streamer happen to get sponsored by a casino. Since these streamers can have an income on views generated by the platform and at the same time get paid by the casino. I like streamers that always remind their viewers to gamble responsibly and that any amazing result on the stream has nothing to do with the viewers gambling experience since the result of gambling is always random.
Exactly, in terms of additional income streaming really paid well if you get sponsor and you have a huge network who followed you and watch your stream videos, plus the chance that you can also earn from referrals, though in the sense of streamers who will give that kind of advice or reminders it's always in the gamblers end playing responsibly and taking care of their finances.
It's your money to take care and even there's some advice like that. If the person/gambler doesn't have that kind of responsible mindset, he will still go to suffer.
