Trading rules are right there; only those who survive can make money.

Last year, a friend came to me with 1800 USDT, looking very determined: "I want to learn some real skills, I don't want to play around." To be honest, I thought—what can this small capital do in the crypto world? But I still decided to give him a try. Three months later, he reconciled with me, and his account showed 80,000 USDT, all without a single liquidation.

This is not luck, nor is it some black technology; it’s because he strictly followed the three survival rules I summarized. These rules are lessons learned from real money. Today, I’ll share them.

**First Rule: Position Sizing is Discipline**

Many newbies go all-in as soon as they enter the market—excited when prices rise, unable to sleep, and staring at the K-line all night when prices fall, completely driven by the market.

The first thing I told him to do was to split the 1800 into three parts: 600 for intraday trading, only one trade per day, and if the market is unclear, better to miss it; 600 for swing trading, stay still until the trend is confirmed; the remaining 600 is an emergency fund, untouched even in dire situations.

It was this allocation that allowed him to retreat unscathed during that sudden crash. Black swan events are common in crypto; overexposing a single position is suicide. The beauty of position sizing is—it gives you an escape route, keeps your mindset stable, and prevents falling into the strange cycle of "earning and reluctant to sell, losing and reluctant to cut."

**Second Rule: Don’t Be Greedy for the Whole Fish**

Most of the time in crypto markets, it’s just oscillation; staring at the screen until you go bald only results in paying fees and being fooled by false breakouts.
