One of the most insane things that people seem to take seriously is "technical analysis" of crypto or stock prices. I have never seen any predictive power behind this, its basically akin to astrology and is more like a fun hobby to help with fantasizing about future wealth. 

Social media has created an entire genre of freelance technical analysts with lots of charts and predictions that never seem to correspond much to reality. Its good fun if you look at it that way but please do not take it too seriously.

So much noise in the TA space. There is one account I follow that has taken a data based approach and doesn't offer advice, but instead creates a thesis. The key difference between this accounts and most is he also provides a negation for the thesis. I have seen him use a data driven approach to predict shifts from bear to bull and back. He isn't always right, but he doesn't pretend to be. I've found his model to be very helpful for investing.
