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.

Yeap 100% 
Opinions almost never have anything in common with the reality.
The simplest example I keep experiencing every time are the sports commentators/expectations/loud headlines that are like 80% of the time happen to be incorrect.
