I have a trading buddy who recently shared his performance in the circle—last October, he bought SOL at $30, endured three waves of over 30% pullbacks, and finally turned a $10,000 principal into $500,000. It sounds like bragging, but he directly posted a screenshot of his holdings, which indeed shows real profits in hard cash.

Why can he hold on while the vast majority of retail investors can only watch opportunities slip away? You might say it's a mindset issue, but I think a more accurate explanation is: he has a clear set of rules, knows when to do what, and when to walk away. That's what most people lack.

His sharing method is called the "Moving Stop Profit Navigation System." The core idea is not to guess where the top is, but to dynamically adjust the take-profit level, allowing profits to run fully while being able to stop in time when the trend reverses. It sounds complicated, but when broken down, it's just five steps.

**First Move: Lock in 30% of your conviction position**

Before buying, set a strict rule—no matter what, keep 30% of your position until the bull market ends. This 30% acts as your psychological bottom line and is also the seed for compound growth. Mark this position clearly; unless the fundamentals completely collapse or a clear bear market begins, don’t touch it regardless of fluctuations. It’s like buying a ticket to participate in a major trend—you must hold on tight.

**Second Move: Once floating profits reach 50% of your cost, immediately raise the take-profit line**

For example, if you bought SOL at $10,000 and it rises to $15,000, immediately move your take-profit level from the cost price to $10,000. What’s the benefit? You no longer have to worry about all your hard-earned profits being wiped out. Use the market’s money to chase further gains, making you psychologically much more relaxed.

**Third Move: Use moving averages to let profits run automatically**

This is the most core part of the entire system. For mainstream coins, use the daily EMA30; for BTC, use EMA20 as the track. The rule is simple and straightforward: as long as the daily close doesn’t break the moving average, keep holding. The moving average will rise with the price, and your take-profit level will adjust accordingly. This way, you don’t need to watch the charts all day or worry about when to sell—the system will make decisions for you. That veteran buddy held through multiple pullbacks with EMA30 and only held on for the main rally.

**Fourth Move: Layered partial profit-taking to steadily lock in gains**

When your profits triple, sell 10% to recover your principal. When it reaches 5 times, sell another 20%, turning that into pure profit. When it hits 10 times, sell 30% to fully cash out. After each partial sale, readjust your take-profit line, locking in profits while not missing out on further upside.

**Fifth Move: Recognize the signals of trend reversal and exit cleanly**

When should you fully exit? There are two signals that prompt immediate liquidation, including that 30% conviction position: one is a daily close below the moving average within three days; the other is increased volume during a decline, but decreasing volume during rebounds. Additionally, if a clear top structure appears on the weekly chart, that’s also a signal to leave. After clearing out, convert 50% of your profits into stablecoins or fiat to truly secure your gains.

In essence, the market fluctuates daily with noise. The traders who last long are those who protect their principal and stick to their rules. When the next cycle arrives, only such disciplined traders will be able to stand firm.
