Most of these streamers think everyone is gullible like others that would be always curious to see more and look for strategy to make fast money from gambling especially when they expect it to be consistent. Gambling is all about risk taking and one need to focus on switch games looking for how to get better luck for profits. I have realized that when you are too curious to make profits just like people that based their success of make money on the perspective of streamers about particular game. Once a gambler does not feel entitled to winning consistently, he will understand that making profits is not always based on what others think.
But it's not a lie in my opinion, it really happens, there are quite a lot of people who believe in what the streamer says, for example with the pattern or strategy they give to players who want to win, so there are people who believe and follow the instructions of the streamer with their strategy or pattern, maybe if they succeed in winning with the pattern given by the streamer, they will believe even more that they can make a profit consistently with their strategy, even though it's nothing more than luck on their side.
No matter how good their strategy is, it won't make them win consistently, because if that really happened, I myself would do it because I want to get money easily just by gambling.
