If we bookmark their market, price predictions from their Youtube videos or posts on X/ Twitter, when we check back some days or weeks later, we will recognize inaccuracy of their predictions.
Experienced and knowledgeable experts can teach us many good educational things and it's good if we can follow and learn from them but we should not make all of our investment or trading positions with complete dependence on their opinion and predictions.
You should try to screen them very carefully, if they are actually good experts then they will be able to provide you proof of how good they are on live, meaning they will tell you something before they even buy it, like tell you "buy when it reaches X" and if it actually reaches that and you buy and then it goes up, you have a proof. I bet you that fake ones will never be bale to provide you that, because they can't.
if you done it well then it could really be making out that kind of long term benefit on which its just normal that you would be having those kind of considerations too.
