I'm not sure about these since you don't think anyone has ever used these methods and been successful in their trading activity. Have you ever met someone you know who you think uses these methods and has made money while trading on them? I'm not sure OP you haven't seen, I believe you just noticed it now, and you bring it up here for people to go check.
However I want you to let you know that there are many other videos like this and some that are even more fascinating than this one, but we are not employing that method since we are unsure of it. Therefore, I believe that in order for a trader to succeed, there is no need to duplicate another person's strategy; rather, all that is required is that you have the essential trading knowledge, develop your own trading style that works for you, and put it to use.
There is no absolute sound financial advice to adopt other than your own analysis of the assets of your investment choice. If your analysis is no better than anyone else's, then you may need to learn to improve that ability instead of trusting 100% in other people's analysis. Crypto investing and trading is done with real money, so don't even try as long as you can't afford to lose.
I'm not interested in watching videos like that because I tend to be more confident with my own analysis. Some experienced people can be made teachers, but I hope it's not more than figuring out how we can add insight, not 100% do what they do.
