Yes it's true Prediction fails many times I have experience and to my knowledge I think we have two type of Analysis
Fundamental Analysis
Technical Analysis
Please In crypto market which one work most?
Seems that you are rushing things here. Crypto trading can't be learned overnight.
Fundamental/Technical Analyses are important here, but they are just only part of your trading skills.
When you are long enough in crypto trading, those analyses are just your guide but when it comes to particular project, better follow their updates and progress.
Some projects don't even follow what you have learned with TAs because they have their own world where their performance depends on what's happening with their developments.
You will find out soon that most of the times here, those TAs/FAs don't matter when it comes to crypto trading.
