At 2 AM, a brother from Jiangsu sent me a voice message, his voice trembling.

"10k USDT, 10x full margin, dropped 3%, how is my account gone?" $VELVET
I opened the records and saw he went all-in with 9500 USDT, without even setting a stop loss.
Many people think full margin is safer and that liquidation is caused by too high leverage. Actually, that's wrong. #美光市值超越Meta跻身全美前十
What really kills you is never 10x or 20x—it's you betting 95% of your capital.
Think about it: a 10k USDT account, full margin 10x with 9500 USDT. A small pullback in the market and you're out. $AAVE
But if you only use 2000 USDT, same 10x, even if you're wrong, you lose a little and still have a chance to bounce back.
$LAB So I've always stuck to just three rules:
First, max 20% per trade. For a 10k USDT account, use at most 2000 USDT at a time. Small losses are acceptable; big losses ruin you.
Second, a single loss must not exceed 3% of total capital. With 2000 USDT open position, set a stop loss in advance, take the loss at 300 USDT and leave. If you're wrong, admit it; admit it and you can keep going; if you don't, next time you won't even have a seat at the table.
Third, avoid sideways markets, only trade trends. The real money is always made when the trend is clearest. Sideways, choppy, wick movements—they look exciting but are the easiest way to get wiped out. #0成本拿2股SK海力士
I had a follower once, 5000 USDT, got liquidated 4 times in a month. Later I made him follow these three rules, and in 3 months he grew it to 8000 USDT without a single liquidation.
He said something I still remember: "I used to think full margin was going hard, but later I realized that position sizing is what truly keeps you alive."
Crypto doesn't lack opportunities—it lacks someone to tell you when to go in and when to stop.
