The market is unpredictable—manage risks to avoid big losses. For most beginner traders, it's recommended to divide your capital into 100 parts for trading, with each trade's stop-loss not exceeding 1% of your capital. Once you become a mature and stable trader, you can make adjustments. Cherish life, say no to all-in. Position sizing calculation: Position size (BTC) = Total assets × Single trade risk / (Entry price − Stop-loss price)
