When I find something tough and publicly proven to be difficult to obtain, and then someone suddenly in his chair starts doing few seconds magic to convince the world that it's truly easy, I find it very hard to accept such a concept. We are all aware that to win in gambling is sometimes accompanied by luck and skill, no one can sit on his wheel and tell me differently.
Even if you read the comments on the streams, if you are a curious person, you will find it hard to believe the games as genuine.
It's unethical but is not prohibited that's why they continue to promote. I'm sure there are people trying to expose them on their comments, I've read some of the comments given by the viewers which they are saying the strategy isn't working and that means they really tried what the streamer is doing. Victims are complaining.
Streamers continue to do it even after they changed their terms as twitch introduced restrictions on gambling-related links.
What makes it unethical? Watching those streams is a form of gambling since you know that if you follow the procedures, you will either lose or gain.
Actually, there are decent YouTubers that preserve their reputation and have taught many of their techniques, but I don't believe in following one's approach, only the foolish do so, and that's why they fall prey.
Tips: Loosing is part of gambling, you can't always outsmart the house or another player. Go with the vibes and learn yourself.
