I believe that in the crypto market there are 2 ways to learn if you are a beginner. The first method would be to learn from your own mistakes. This is a method that is generally applied in everyday life and is the most efficient, but it is not indicated on the crypto market because it is about losing money. The second method involves more information and you learn from the mistakes of others. I recommend good information.
I think you are right, But do you know that you can also learn when you do not make mistakes ? By trying out a new stuff and doing things differently.
I think it is hard to learn from others mistakes, because you will not be made aware the steps that led to the mistakes.
And regarding good information, you need to source for that yourself.
Thats why personal research function is compulsory for every crypto currency trader or investor and even bounty hunters.
