The best learning is from your own trading experience. Perhaps some courses offer premium lessons on trading but it would be better to learn from the experience of trading on your own. or you can see tradingview how those who are experts in predicting.
Basic technical learning must be known before starting to enter trades, especially crypto that fluctuates highly. There are many traders who until now didn't use the technique at all because they didn't learn it since they started trading.
Maybe they are profiting even without technique?because if not for sure they had already quit trading and just holding now.
Actually i believe that the BASIC technical Learning can be acquired along the way,specially if you are active in this forum that offers too many knowledge in all terms of profit options.
It's true tho that you can acquire basic technical learning along the way however, it is better to learn it before even starting so you can minimize your chance of losing. And so, he would not be like those who quit trading immediately because they lose huge money at the beginning of their trading journey.
