fake.
they are just marketers/commercial who sell their courses (but they arent real traders)
My mentor for exemple , i was very lucky to find him because he dont show signs of being rich (no ferrari/lamborghini , no dream selling, no building photos/beach, no clickbait). he just make a webinar per week and post it on youtube (with more or less 1000 views per webinar). I found it thanks to God , cant tell you how but finding a real trader who sell real course its like searching needle in a haystack
its really modest, really hard to find but when you find it you know he is very rich without him showing it ( you can observe it in the way he explained the trades he take)
the best advice i can give you to find a mentor through youtube is not looking into videos with hundred thousands views or millions views. you’ll have more chances to find a real trader who have very few view (like 1000 views per video) even if it still difficult to find one
