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.

I think that technical analysis works from the point of view that many people believe in it and trade as if it exists — hence we have all the figures; 
It doesn't help us to identify whether the price goes up or down, but helps to identify points of interest (potential big movements) - where trading basically makes sense (higher risk - higher reward)..
When making the decision itself it’s perfectly fine to use basically any pattern, they all are equal in predictability, — be it technical analysis or a coin toss, or any esoteric practices — if (and until) that actually works for you (call that luck)..
