That's the reason why I've stopped watching those crypto vloggers, they all say the same thing and just because they've got something to say, makes them an expert.
But no matter what the situation of the market, they'll just continue to do it as they've loved it as a passion and also because of monetization. It's better to read a brief news about the market and good to read topics and articles about what had just happened to the market.
The YouTubers usually give you a positive side of the picture and they will most probably say that bitcoin and crypto will pump in the short term. Most people want to hear this and hence their focus is to make content that is liked by many people but it may not be authentic.
I think if you are a crypto trader, you should avoid those crypto vlogs and advice through youtube as they will lead to a loss. Also sometimes I see these YouTubers shilling some low cap coins to go 1000x. I wonder if they are being paid by the project's owners to make such predictions for their coins

It could be that what you say is true, but back to their media because making content or vlogs is the same as us who want to be paid, so sometimes what they make is beyond our instincts, yes or no from their explanation.
I've tried to practice it from the results I saw on their youtube but the results are nehi aka I feel like I'm losing.
