At 3 a.m., my phone suddenly rang.

It was a friend from Hebei, speaking urgently: I opened a full position with 10,000 USDT at 20x leverage, and the market only pulled back 5%, but my account blew up! How could this happen? There were no signs at all.

I looked at the trading record, and my goodness, full position with leverage, no stop-loss set. This isn’t trading, this is suicide.

Actually, many people misunderstand this. The biggest problem with full position trading isn’t leverage, but position management.

Let’s look at it from a different perspective: you can handle 100 kilograms, but suddenly a 500-kilogram weight appears—that’s definitely death. That’s the logic of full position trading. With the same leverage multiple, the outcome can be worlds apart depending on the position size.

Specifically, suppose your account has 1,000 USDT, and you invest 900 USDT to open a 10x leverage position. A 5% market fluctuation will wipe out your account. Conversely, with the same 10x leverage, if you only invest 100 USDT, it takes a 50% move to liquidate. Same leverage, vastly different results. That’s the problem with that guy—putting 95% of the principal into a full position, and the market moves slightly, and it’s gone.

So, if you want to make big money, first learn how to survive longer.

I’ve been trading full positions for over half a year, never blown up my account, and instead doubled my funds. There are three key principles:

**First: No single trade should exceed 20% of total funds**

With a 10,000 USDT account, invest at most 2,000 USDT. Even if you make a wrong call and set a 10% stop-loss, the loss is only 200 USDT. Limited damage to the total funds, with opportunities for rebounds at any time.

**Second: Single loss must not exceed 3% of the account**

This is crucial. With 2,000 USDT and 10x leverage, if you set a 1.5% stop-loss, the loss is 300 USDT, exactly 3% of the total. Even if you hit stop-loss several times in a row, it won’t hurt your core.

**Third: Avoid opening positions in choppy markets**

When the market is sideways, do nothing. Wait for a real trend to emerge before entering. Also, don’t add to positions impulsively—emotions will lead to mistakes.

In short, the true purpose of full position trading isn’t gambling, but to give your account a buffer. The premise is to test with small positions, strictly follow risk control, and aim for stability, not overnight riches.

A follower once kept testing the edge of liquidation every month. After following my approach for three months, a 5,000 USDT account was suddenly turned into 80,000 USDT. He was stunned and said, “I used to think full position was like risking my life gambling. Now I realize, full position is actually to keep myself safer.”

Really, spend less time guessing market directions, and more on managing positions and risks. Patience is faster than rushing.

There are many opportunities in the market, but only by surviving long enough can you truly seize those huge profit moments.
