I spent 100u to join the group, and ended up losing 1200u😅

Sigh, I'm still a newbie, lacking understanding. Today, I was browsing the square and saw a post from some jerk. He made suggestions that sounded quite professional, but in reality, they were nonsense. If I relied on my own practical experience, I would still earn steadily. This is just ridiculous, I lost everything back! I couldn't handle it anymore, so I closed my position! It seems I need to stick to my own ideas in the future and strive to achieve ten thousand oil!
