DOTUSDTTechnical analysis is just like when you take a survey for a new business you are about to get into. it helps you make better and informed decision on what ever financial market you find yourself (whether crypto, forex or stocks)... on the best possible zones to enter and exit the market... it also helps you make plans for informed risks and rewards associated with the trade youre about to take..
given that there are many trading strategies, its best to stick to a mentor you trust and learn diligently so you can formulate your preferred pattern... this is necessary because it helps you avoid the confusion and frustration that comes with information overload that lingers in from trying to learn too many strategies.
