Yes, you are right. No one helps in the beginning. It doesn't help with proper guidelines; we must learn from mistakes. The more mistakes we make, the more we learn from them and aim to avoid making the same mistakes in the future. No one teaches someone by hand; you must know yourself and strengthen your foundation. Problems must be faced, and one cannot enhance oneself. Be firm at any moment. The only thing that must be achieved anyway is to smile in victory at the end.
But as a beginner, you can still reduce the number of mistakes you make before you finally learn how to trade and reduce your losses.
I believe one of the reasons why some traders add their mistakes and trading experiences online is for people to watch, read, and learn about them so that they can also avoid making such mistakes again in the future.
Mistakes can't be avoided completely, but most times we can use the mistakes made by other traders to enlighten our crypto trading knowledge.
