have you ever booked a course with a trading expert in the past, for example? the courses are definitely justified, as the information is conveyed much better and in a much shorter time than if you have to teach yourself everything via youtube and co. so especially for people who want to get into the subject relatively quickly, such courses are very suitable, but of course they also cost (sometimes even a lot of) money.
Experts can teach helpful and insightful things for newbies and learners but they can always be wrong with their predictions on the market.
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.
