Their predictions are not the same, though. Of course, few of them are right. Personally, I believe in them, especially if my analysis would align with theirs. I mean, we don't have to follow them blindly; we can only agree if their technical analysis is backed by various reasons or factors that would affect the price movement going towards the price movement they are predicting.

Any platform is useful; there are lots of traders who make vlogs for content. But you can easily spot those who have good analysis because they have a good number of followers or subscribers.
