I do not use stop loss again since 3 years ago when I saw its disadvantages. You will know what that I am talking about.
I trade with low leverage.
I average. People that average will likely not be using stop loss.
Those traders that uses stop loss are those that uses high leverage, or trading a very volatile altcoins and not averaging.
yes, we need that even if your analysis is 100% perfect, remember that crypto is very volatile, many things can happen so if you want to take care of your capital, set a stop loss for your safety, even if you can sleep on it, and of course, put a take profit, that would help
