#数字资产市场动态 In contract trading, position management is the first hurdle. My experience is to memorize this formula: never risk more than 2% of your principal on a single trade. For example, suppose you have a capital of 10,000 USDT and want to go long on BTC, opening at 60,000, with a stop loss set at 58,800 (a 2% drop). Then your position size is 200 USDT ÷ 1,200 = 1.67 BTC, with leverage controlled at 5-10 times for safety. $ETH Similarly.

Especially for beginners copying or leading trades, it is strongly recommended to use isolated margin mode, allocating 10% of your capital to trade a single asset. This way, even if you hit a bad trade, your entire account won't be wiped out. Many people lose money very quickly; frankly, it's because they didn't manage their positions properly—this is how contracts work. Larger positions turn small gains into small losses, and small losses into liquidation. Instead of chasing those tiny profits, it's better to stay alive and wait for the next market wave.
