There's no such thing as perfect trading so it is normal to fail in crypto trading especially if we are just at the beginning of our journey. Failing doesn't mean that you won't succeed but rather it can be a big motivation for us to learn and be better. If we have experienced failure, we already know what to expect and through that, we can handle our emotions. Dealing with our emotions is quite hard sometimes because trading could give us a roller coaster ride of emotions so we should be firm in handling what we feel.
Failing is horrible if you do not learn from it. But it is one of the best teachers if you have learned something from it as well. I have failed many times while trading and some of them were out of nowhere and I couldn't understand why I lost, and yet when the time comes I learned from my mistakes and thanks to that I am not making as many mistakes as I used to, which is an amazing thing.
I hope that most people will do something similar when the time comes and we will end up with something much better on the long run. I know that's not going to be easy for the newbies, wasn't easy for me neither, but when they start to learn from their mistakes, they will start to become a great trader.
