Looking at the remaining few hundred USDT in the account, fingers hover over the open order button, and the mind is filled with thoughts like "If I could triple my money, I could break even." Hold on first, don't rush to place an order.

Here's a real case: when the account only has 500U, it's the easiest time to make the most dangerous decisions. But some people operate in the opposite way—using 3 months to grow 500U to 18,000U, with zero liquidation during the process. The secret isn't luck, but strictly following three survival rules.

**First Rule: Diversify Positions, Don't All-In**

The common losing pattern in crypto is losing everything in one shot. That friend split 500U into three parts: 150U for short-term trades only on BTC and ETH, exiting immediately if the price moves more than 3%; 150U for swing trading, only acting when the daily chart shows a clear breakout; the remaining 200U as "absolute safety," not touching it even if it loses, as it’s the seed for a rebound.

Full-position traders can be wiped out by a single spike. Those who know how to keep some reserve can withstand a correction even if their judgment is wrong. Position management isn't about reducing your profits; it's about surviving one more day, one more year in this market.

**Second Rule: Follow the Trend, Avoid Consolidation**

Most of the market time is spent in poor sideways trading. Small funds frequently enter and exit here, with fees and slippage eating into profits. The real opportunity lies in the 30% trending market.

Before entering, two conditions must be met simultaneously: 15-minute K-line shows continuous volume increase, and the daily MACD shows a golden cross or death cross. Once the trend starts, there's a chance to earn several times the profit.
