If I can only keep one habit: write down "what's the worst possible loss" before opening a position, and avoid it if it exceeds that. To put it simply, I can't hold onto spot positions because I get itchy, and I get stubborn about liquidation when trading futures; it's not that my skills are poor, it's just that my position management isn't disciplined. Recently, cross-chain bridges have been hacked again, and oracles are giving strange quotes, and everyone is refreshing "waiting for confirmation"... I'm the same, waiting first, don't rush to be the first to be smart. After seeing the liquidation line so many times, I understand that staying alive is more important than checking once; let's leave it at that for now.
