When doing contracts, you must set a stop loss; when you make money, you must stop profit and withdraw cash; you must not carry orders against the trend. The first step for many people to lose money is to carry orders and think that they will run away after they get their money back, and run away after they make some money. If you carry one loss out of 10 contracts, your principal may be gone🤷‍♀️#BTC走势分析
