#数字资产市场动态 Someone asked me: "Holding 100,000 USDT in spot, watching the price go up and down, my heart races with the flickering screen. Is there a scientific way to survive long-term without just gathering dust?"

My advice is actually quite simple—summarized into six iron rules. Carefully following them can gradually create an account curve of 'small losses, big gains.' The core idea is to think in reverse: first calmly calculate how much you can lose at most, then consider how much you can earn.

**1. Quantify Your Risk Bottom Line**

For example, with 1 million in capital, set the maximum loss per trade at 20,000—this line must never be loosened. With this loss limit, you can back-calculate your position size: if your stop-loss is only 5% away from entry, your position should be lighter; if you have 20% stop-loss room, you can take a larger position. Keeping this bottom line ensures your account always has some buffer.

**2. Always Enter Light on the First Trade**

Even if theoretically you can allocate 20% of your capital, only risk 10% on the first entry. If the market moves against you, your account only loses a small part; if your judgment is correct, you can gradually add the remaining 10%, bringing your average cost down. During the trial-and-error phase, staying alive is more important than being right.

**3. The Secret to Adding on Profits**

Don’t listen to those who say "adding on floating profits is a death trap." The key detail is: before adding, set a trailing stop-loss; use the profits already gained to cover potential losses on the new position. This provides protection: if the price continues upward, you multiply your gains; if it reverses, you only give back the profits, and your principal remains safe. $BTC’s rise is the best test of this method.

**4. Increase Position When Net Value Hits a New High**

When your account net value hits a new high, treat the additional profits as "pocket money" and modestly reduce your total position size; conversely, if the net value retraces more than 5%, immediately cut back to your initial allocation. Remember: bottom-fishing during a loss can trigger a blow-up; timely stop-loss during a retracement is the key to survival.

**5. Withdraw Funds After Big Gains**

The day your account doubles, withdraw more than 50% of your principal—this is not cowardice, but wisdom. No matter how good the numbers look on the exchange, they can’t compare to real cash in your bank. Opportunities are everywhere daily, but once your principal is wiped out, it’s extremely hard to bounce back.

**6. Repeat the Cycle**

Run this logic repeatedly: quantify risk bottom line, trade lightly, add on floating profits, adjust positions against human nature, and withdraw at critical moments. Follow each step by the rules, and emotional swings will naturally subside, gradually steering your account upward.

The crypto market never lacks opportunities; what’s missing are those who can survive long enough. With the right method, you can turn time into an ally.
