#数字资产生态回暖 Eight years in the circle, the most memorable period is locked in 2017—the wild era of altcoins.$AI 。

At that time, I heavily invested in $ADA, starting to accumulate in batches from a low of $0.03. No one predicted that within just three months, it would surge to $1.2. The numbers in my account nearly multiplied forty times. The first thing I did every morning was to check the market, watching the zeros behind my assets grow longer and longer, and I was already planning how to use this money to buy a house outright in the city.

But greed is harmful. I never pressed the sell button.

ADA suddenly collapsed, crashing to $0.2 like a fall from a building. The unrealized profit evaporated by eighty percent overnight, and the dream of buying a house was shattered. That huge loss taught me a lifelong lesson: in the crypto world, those who buy are rookies; real players know how to sell at the right moment.

Over the years, I have developed a profit-taking and stop-loss system that is especially suitable for ordinary investors who don't have time to watch the market day and night.

**For profit-taking, I use the "Stepwise Decreasing Method":**

When a coin rises from $1 to $2, sell 30% of the position first—this way, the principal is basically recovered, and the remaining part is like free money, which completely changes your mindset. When the price continues to $3, sell another 30%. For the remaining 40%, I will set a trailing stop order, and if it pulls back 15% from the high, I will close all positions. This way, you won’t hold on blindly and miss a big surge, and you also ensure that profits won’t be wiped out. $ETH Fluctuations are normal; the key is discipline.

**For stop-loss, I have only one strict rule: the maximum loss on any single trade must not exceed 5% of the total account.**

Every time I open a position, I immediately set a conditional order with a -10% stop-loss. It’s like buying insurance for the trade. Don’t worry about missing opportunities because of this—there’s plenty of market; but once the principal collapses, you lose the qualification to turn the situation around.

In these eight years, I’ve seen too many stories of getting rich overnight, and I’ve also witnessed countless people losing everything on the rollercoaster of rises and falls. The ones who can truly walk away with profits unscathed are invariably those who treat discipline as faith. Calm mindset, ruthless tactics, strong execution—these three are indispensable.
