Trading's core goal isn't to chase single-instance big profits, but to build a stable income system that can compound for a lifetime.

In the crypto world, those who truly survive and last longer are often not the smartest, but the most disciplined. After years of experience, I’ve summarized three repeatedly validated contract trading rules to share with everyone.

**Rule 1: Make money, but more importantly, protect your gains**

Making money isn't difficult. What's hard? It's ensuring that the profits you earn don't get completely pulled back in a wave.

For coins like SOL, which have rapid gains and sharp volatility, you need to be extremely vigilant when the price rises by 10%. If it falls back to your cost basis, don’t hesitate—take profits decisively and exit. Don’t wait to bet on the highest point—that’s a gambler’s game.

How to operate specifically? When profits reach 20%, lock in at least 10%; at 30%, lock in 15%. Using this "rolling take profit" method, let profits accumulate repeatedly. The market is like waves; learning to protect gains during upward waves is what a professional trader does.

**Rule 2: When losing, stop-loss is more important than judgment**

Before each position, mark your stop-loss line. For example, if a loss reaches 15%, close the position immediately—that’s the bottom line.

Never hold onto illusions like "waiting for a rebound to sell." That’s the most money-burning idea in trading. Losses themselves aren’t scary; operational mistakes aren’t scary; the most terrifying thing is refusing to admit mistakes and being reluctant to exit. Trading isn’t about saving face; it’s a serious survival competition. Recognizing mistakes one second earlier increases your chances of survival.

**Rule 3: After selling, if it drops, dare to buy again**

This rule may seem counterintuitive, but I’ve tested it countless times in practice.

For example, you sell ETH, and afterward the price drops. If your judgment remains unchanged—that you still believe in this wave of the market—then buy back the same amount at the original or even lower price. What’s the effect? Your holding amount stays the same, but your available funds increase. Even if you miss the rebound in the end, don’t regret it; if it rises, you can re-enter, and if it falls, follow your discipline and cut losses. This "sell-wait-buy" cycle helps you mitigate the risk of missing out and always keeps you in control.

In short-term trading, it’s ultimately a contest of rhythm and discipline. Quick in and out isn’t reckless; taking profits when the time is right isn’t cowardice; staying on the sidelines isn’t giving up opportunities.

The key is—can you maintain your rhythm, mindset, and capital amidst market volatility?

Remember one thing: in crypto, it’s never about who makes money the fastest, but who survives the longest. Stability is the greatest form of compound interest.
