At 3 a.m., my phone was vibrating wildly.

Ahao's friend called directly with a shaky voice: "Mr. Wang, I used 10,000 USDT with 20x leverage to go long on full position. The market just retraced 5%, and all my money is gone in an instant!"
I looked at his trading record and immediately understood—full position + 20x leverage, and no stop-loss.
Many people think that full position can better withstand volatility, but actually the opposite is true: the larger the position, the faster the liquidation.
Here's a simple example: with a 1,000 USDT account, if you open a 10x leverage with 900 USDT, a 5% market reversal can wipe you out; but using only 100 USDT with 10x leverage, the market would need to move nearly 50% to liquidate. His problem was simple—he put 95% of his principal in at once, and a slight retracement took him out.
In fact, as long as you follow three rules, the risk is completely different. First, no single position should exceed 20%, with a maximum of 2,000 USDT in a 10,000 USDT account; second, limit single-loss to within 3% of total funds, and set stop-loss in advance; third, during sideways markets, minimize trading and only enter when a trend breaks out.
Once, a fan followed these three rules and turned 5,000 USDT into nearly 80,000 USDT in three months. He later told me one thing: "I used to think full position was gambling for my life, but now I realize, full position is actually about surviving longer."
The true winners in the crypto world are never the ones who make the fastest gains, but those who can stay in the market longer.
Less gambling on direction, more control of position size—many times, slow is actually the fastest way.
