I do think that traders needs Technical Analysis knowledge and can get more benefits from it if mastered. While investors would get more benefits from Fundamental Analysis. I come from that decision because :
Indeed, a trader needs knowledge about TA and moreover master it in order to analyze the market once they want to take the position. This analysis is very helpful for trading in the Spot market or even in the future or trading with leverage, to set the Long or Short position.
Basically, TA is more complicated to master moreover it is about analyzing the graphic, and the possibilities of the charts to rise up or go down at the certain rate. TA is always needed for traders even there is no specific news that will be the FA. But if there is specific news in this case certain FA, it will also help to get a stronger TA at that time.
I wouldn't really be believing the situation to be fair, it sounds like that TA and FA are not even in the same room for me, and I agree with you that any good trader should be able to just read the TA with just corner of their eye and know what they are looking at. Like if they see a chart, and a line drawn, they need to understand what it is without further explanation, and that is how you become a great trader.
However, crypto is easier than that and doesn't require you to master it, even if you understand the momentum, you should be doing fine, and if all else fails, just buy and hold it for a decade, you will profit one way or another anyway.
