When I started trading I made a lot of stupid mistakes. Yes, you can do stupid things even trading on spot. I purchased a bunch of random coins during their ATH. I used copy-trading and lost everything I invested because of some random Chinese guy I delegated my money to. But looking at these now, I understand that I paid for a valuable experience.
Don't blame yourself for making mistakes. But you MUST learn from them, otherwise you lost your money for nothing.
