Last night, I was scrolling through my phone and saw a voice message from three months ago. It still sounds shocking to me.

The person sending the message is a friend who has been trading contracts for two years. At that time, his voice was breaking: "Brother, save me! I opened a long position on ZEC with 10x leverage using 10,000 U as the principal, and I was forcefully liquidated after just a 3-point pullback. What kind of logic is this?"

Let him send a screenshot of his position, damn it, 9500U went all in directly, without even setting a stop-loss.

This is the biggest misunderstanding most people have about the full margin mode - thinking that full margin can withstand fluctuations, but in reality, using it incorrectly can lead to faster losses than isolated margin.

The main point is: the root cause of a total liquidation does not lie in the leverage multiple, but in how much money you bet on one direction.

Just understand it by doing a simple calculation -

Similarly, 1000U principal:

- Open a 10x long position with 900U, if the market reverses by 5%, it goes directly to zero.
- Use only 100U to open 10 times, it requires a 50% drop to trigger forced liquidation

My buddy just dumped 95% of his funds into one cryptocurrency, then leveraged it 10 times, and as soon as the market fluctuated a bit, he got wiped out.

**So how should the full position be played?**

I used a full margin for half a year without getting liquidated, and I even doubled my investment, by strictly adhering to three rules:

**Rule 1: Do not exceed 20% of total funds for a single position**

An account with 10,000 USDT can move a maximum of 2,000 USDT at a time. Even if there's a 10% stop-loss due to a judgment error, the loss would only be 200 USDT, and the main force is still there, ready to start over at any time.

**Rule 2: Each time, the allowable loss must be controlled within 3% of the total assets**

Use 2000U to open 10 times, set a stop loss at 1.5% in advance, triggering a loss of 300U (exactly 3% of the total position). If you make three consecutive wrong trades, you can still preserve 90% of the principal.

**Rule Three: Do not act during sideways markets, do not increase position when in profit**

Bet only when the trend is clear; no matter how tempting the fluctuations are, they are traps. After opening a position, never add more chips; don't let greed take over your account.

**What is the essence of full margin?**

It is not a tool for gambling with one's life; it is designed to leave a way out for oneself. The core is summed up in two words - **light testing + strict control**.

A fan named Yueyue was liquidated before. Following this set of rules for three months, he steadily grew from 5000U to 8000U. He said, "In the past, going all in was a gamble for my life; now going all in allows me to sleep more soundly."

Keep a close eye on these three lines (20% per transaction, 3% stop-loss, no movement in sideways markets). In the crypto market, it's never about who makes money the fastest, but rather who survives the longest.

Less guessing on direction, more focus on positions. Slow is truly fast.

Don't wait until being liquidated to regret it; try lightly and control strictly to survive longer and earn more steadily in this market.
