#以太坊大户持仓变化 Entering into contracts isn't about making U for a lifetime, but about earning U for a lifetime—this phrase sounds convoluted, but it reveals the blood and tears lessons of many old rookies.

Today I want to share a few hard truths about surviving and staying steady in the crypto world. These are not some profound technical analyses, just battle-tested practical experiences.

**Point 1: When you make money, think about how to protect it**

When you buy a certain coin and it rises more than 10%, don’t think you’ve become a master. The market is merciless; the peak often occurs at this very moment. Once the gain reaches this level, be cautious—if the price falls back to your cost basis, don’t wait, sell immediately.

If it reaches a 20% profit, set a rule for yourself: this trade must secure at least 10% profit before selling. Unless you are absolutely sure this is a temporary top, don’t be stubborn.

If it rises 30%? Then set a bottom line: at least 15% profit secured before exiting.

This approach may seem like you’re earning little, but you’ll notice a magical phenomenon: profits will compound themselves. Because you’re no longer driven by greed, you can more clearly grasp each opportunity. Many people lose money because they can’t let go of that last 5% profit.

**Point 2: When you lose money, have the discipline to cut losses**

Conversely: if the coin you bought drops. Set a stop-loss level—this number varies from person to person, but 15% is a common reference. When it hits that point, cut your losses—no excuses.

I know human nature makes it hard to accept losses; your mind is probably thinking “wait a bit longer, it will rebound.” But this mindset is like a gambler clutching at a last straw—sometimes it can save you once, but nine times out of ten, it will harm you.

Stop-loss is not about giving up; it’s about rationality. If your entry was wrong, paying tuition is justified. Some people cut losses and then the coin rebounds, making them feel foolish. But think of it this way: this loss prevents a bigger blow-up next time.

Before entering each trade, you must decide where to set your stop-loss. This is not a suggestion, it’s a mandatory lesson.

**Point 3: After selling, if the coin drops, buy back at the original price**

This is an interesting tactic. Suppose you sold a coin at the right time earlier, but after selling, it drops. If you still believe in its long-term prospects, consider buying back the same amount at the original price.

On the surface, your coin holdings stay the same, but you have more cash in your pocket. The beauty of this method is: you maintain exposure to the coin while extracting liquidity from volatility.

Conversely, if after selling it didn’t drop much, and you didn’t buy back, but later the price recovers to your selling point, then you must buy back unconditionally. Although it costs more in fees, this avoids the most painful thing—missing out.

You can combine this principle with stop-loss: buy back when the price returns to the original level, stop-loss if it continues to fall. If you do this several times and find the coin’s price is too volatile and unstable, then it’s time to switch tracks—there’s no need to hang on a single tree.

**In conclusion**

Short-term trading is all about discipline. Quick in and out isn’t reckless, chasing hot spots isn’t aimless, taking profits when the time is right isn’t cowardice, and sitting on the sidelines isn’t quitting the crypto scene.

Don’t torment yourself with the idea of the lowest or highest prices—your profit should come from the reasonable part of the trend, not every point. Surviving this wave of market fluctuations is always more important than chasing maximum profits.

ETH, mainstream coins, small tokens—all follow these three rules. Whether you succeed or fail depends on your execution.
