I find that I can't hold onto spot positions, and I always want to "hold on a little" with contracts. To be honest, it's not that my skills are lacking, but that my position size is too greedy. My straightforward advice: first solve the "Will I die?" problem, then think about "Can I make money?" Before opening a position, set a maximum loss limit, for example, losing no more than 1% to 2% of my total position. When reached, close it—don't tell yourself stories; don't go all-in on spot either, split it into several parts. If it drops, you still have bullets; if it rises, you won't be left with an empty position and regret. Recently, hardware wallets are out of stock, and phishing links are everywhere. The more these situations occur, the more you should avoid impulsively clicking or authorizing transactions. Safety operations are often more valuable than guessing the market direction.
