Now about whether or not you need to learn market analysis, the answer is yes, there are two main branches when it comes to this, you can either learn fundamental analysis, technical analysis or both, fundamental analysis takes a look as the name implies at the fundamentals of a coin and tries to determine if the coin is good enough, and if it is then you invest in it for the long term, technical analysis on the other hand concentrates almost exclusively on the price as those that use it believe the price already reflects everything you can know about the asset you are trading, both are effective you just need to choose the one it fits you better and then dedicate a lot of time to improve your skill in one or both of those disciplines.
