If you know anything about trading, I am confident you can tell yourself that if you see something on YouTube or Twitter, you will know if the influencers are telling the truth about trading. Because, in my opinion, the majority of them have only a rudimentary comprehension of trading.
They just appear to have a broad knowledge of trading, but the truth is that they only know the fundamentals. That's what I've found among YouTube content providers, even though they occasionally miss the essential explanation in trade.
The majority of those influencers are either lying through their teeth, and they are simply making it seem as if they know what they are talking about, something not too difficult as the majority of those that watch their videos know nothing about trading, or they know how to trade for real, but since they are trying to get views and subscribers they have decided to twist the facts a little bit in order to give more interesting predictions and attract people in this way.
