Position management advice for everyone: For example, if you take out 30,000 U to trade contracts, my suggestion is to divide it into three parts, each part being 10,000 U. Each time you Enter a Position, use one of the parts to open the position, with a fixed 10,000 U, BTC not exceeding 10 times, and altcoin not exceeding 5 times. If you lose money, for example, a loss of 1,000 U, you can supplement 1,000 U from outside. If you make 1,000 U, you can withdraw 1,000 U. Ensure that every time you Enter a Position in the recent period, you can maintain a fixed position of 10,000 U. Until you have earned 60,000 U using the 30,000 U in this way, increase each part of your position to 20,000 U and trade that way. The benefit is:

Point 1: Split Positions + Low Leverage to avoid being liquidated by the exchange's spike, which could result in losing all your funds.
Point 2, avoid problems like the one you mentioned. If you get overconfident one day and lose everything, at most you'll lose 1/3, and the remaining amount can still give you a buffer opportunity.
Point 3, maintain a fixed Position. Whether you are in a loss or in profit, you can keep a relatively calm mindset, which can help stabilize your mentality.
My habit when entering a position is to go all in at once. For example, for a 10,000 USDT position, I fully invest in one altcoin at a time during market movements. Going all in means using 1/3 of my funds for the position, investing in altcoins at 5x and BTC at 10x, thus entering and exiting with a full position. This approach allows me to have a more precise and accurate grasp of my entry points. If you always use stop-loss orders and low leverage, it's impossible to get liquidated.
If everyone is tight on funds, or currently facing significant losses, or in debt, don't deposit too much money. Just deposit 1000 or 2000 yuan and divide it into 3 parts, and take your time with it. Don't think it's too little; 1000 yuan per part is only 300 yuan, and in this market, any amount can be significant. This is an important point.
Suggestions for reducing losses: 3 points:
First, do not use high leverage. Altcoins over 5 times and BTC over 10 times are considered high leverage. Using high leverage is always a one-way street.
The second point is, do not go against the trend. When the price has risen and you want to short, although there are shorts available, you need to remind yourself that you cannot participate in this market. It is better to miss the entire cycle than to try to touch the top or catch the bottom against the trend.
The third point is that trading must be logical. Don't just look at the charts.
