Many people say that full-position liquidation is because of excessive leverage, but the root of the problem actually lies in position allocation. Let's look at a straightforward comparison to understand:

For an account with 1000U, if you open a 10x leverage with 900U, a mere 5-point move in the opposite direction will wipe it out; but if you only use 100U to open the same 10x position, it takes a 50-point move to be liquidated. Both are full positions, but the tolerance for error is worlds apart.

Many people around me have been wiped out because they pressed all-in orders and encountered small market adjustments. In contrast, traders who stay alive rely on these three strict rules:

**Three Ironclad Rules for Position Management**

1. Limit single-position size to 20%. For a 10,000U account, invest at most 2,000U per trade. Even with a 10-point stop loss, only lose 200U, leaving the overall account intact and with capital to recover.

2. Do not lose more than 3% of total funds on a single trade. For example, with a 2,000U account using 10x leverage, set a 1.5% stop loss, which results in a 300U loss—exactly 3% of total funds. Even if you make several mistakes in a row, it won't break you.

3. Do not open positions during sideways markets; do not add to profits. Only act when there's a trend breakout. Stay put in volatile ranges, and once entered, stick to the plan. Avoid being led by emotions of rise and fall, which helps prevent deepening losses.

The essence of full-position trading is not gambling, but scientifically allocating error tolerance within limited capital. A fan once kept getting wiped out every month, but by following these rules for three months, he grew his account from 5,000U to 8,000U. Staying alive in the crypto world depends on this discipline.
