At 2 a.m., my phone suddenly kept vibrating nonstop. An alert from a trader kept coming in, with all the voice messages filled with hurried breathing:

"I used 10,000 USDT to open a full position with over 10x leverage. It only pulled back 3%, and everything was gone—how did my money disappear?!"

I checked his trading record—using 9,500 USDT to open a full position with 10x leverage, without even setting a stop loss. This is one of the most typical liquidation cases I’ve seen.

Many people get it wrong. They think that full position means they can withstand larger fluctuations. In reality, improper full position operations actually lead to faster liquidation.

**The real culprit of liquidation: not the leverage multiple, but the position size ratio**

For example, in a 1,000 USDT account:

- Opening with 900 USDT at 10x leverage causes a 5% adverse move, and the account is directly liquidated.
- The same 10x leverage but with only 100 USDT, requires a 50% adverse move to be liquidated.

The trader who used 95% of his principal all in, and was triggered to liquidate after a slight pullback. This isn’t the fault of leverage, but a problem of position management.

**Three ironclad rules: I’ve been using full position mode for half a year without liquidation and even doubled my funds**

**First rule: No single position exceeds 20% of total funds**

For an account of 10,000 USDT, invest at most 2,000 USDT each time. Even if you’re wrong and stop out at 10%, only lose 200 USDT. The principal remains intact, and you can wait for a rebound opportunity at any time.

**Second rule: Limit stop-loss to within 3% of total funds**

For example, with 2,000 USDT at 10x leverage, set a 1.5% stop-loss in advance, risking at most 300 USDT. A few consecutive mistakes won’t hurt your core.

**Third rule: Don't open positions during sideways trading; don’t add to profits**

Only enter when the trend is clear. Even in tempting sideways markets, exercise restraint. Never chase after opening more positions once they’re set. Emotional interference is the invisible killer of liquidation.

**The purpose of full position: a buffer mechanism, not a gambling tool**

A fan once kept liquidating every month. After following these three rules, he increased from 5,000 USDT to 8,000 USDT in three months. He then said: "Turns out, full position isn’t about gambling your life; it’s about surviving longer."

This sentence captures the survival rule in the crypto world—the goal isn’t to earn faster than others, but to outlive them. Manage your positions well, accumulate slowly, and opportunities will always be there.
