For me, every loss will give us insight into where we made a mistake while trading. It might not be useful for the next move but it can be applicable for the future one when the time calls for it. Still, to be precise, it's a maximum of 2-3 losses because by then I came to know that my strategies aren't working and what to do for next. To not make the situation complicated, I will start to apply different strategies for one coin to another. Everyone in the crypto industry must have experienced the loss at least a time still we all stands here and trading. We shouldn't stop trying until we succeed.
