After many years of experience, I realized that losses are part of the proccess trading. Losses happen to the best traders. The best traders I know do not have a 100% win rate.
When I take a loss, I sit down in order to:
a) review the trade
b) learn from my loss
What do you do when you take a loss?
It's true and right what you say here, op. As long as you don't forget that while you're doing trading, you shouldn't stop learning here. Be an empty cup; just always absorb what you teach or discover your trading knowledge because this will push you to rise and move forward in life.
And what others have said here is also correct: there are no perfect traders. Remember that trading is not easy to understand, but once you know how to make a profit here, you will definitely be able to make a profit in the crypto space anytime. .
