#美国就业数据表现强劲超出预期 From 40x unrealized gains to a complete wipeout: The lessons I learned during the 2020 altcoin frenzy

After years in the crypto space, there's one thing that always sticks in my throat—the crazy boom of altcoins in 2020. That experience left the deepest mark on me, paid for with money and lessons.

I remember I set my sights on $ADA. Starting at $0.03, I built my position in several rounds. Over three months, it surged to around $1.2. The numbers in my account changed magic-like every day, with unrealized profits nearly 40 times. Every morning, the first thing I did was check the candlestick charts, already planning what to do with that money—buy a house, a car, all sorts of plans queued up in my mind.

But human nature's greatest enemy is greed. I hesitated to hit the sell button. Then, the market taught me a lesson. $ADA suddenly crashed, plunging from its high to $0.2. That 80% unrealized profit was like being thrown out of the window in one go. The psychological gap was enormous, as you can imagine. At that moment, I understood what "$0G" means—not just about a single coin, but the ultimate punishment for greed.

This bloody lesson made me realize one thing: in the crypto world, buying low is just basic skill; the key is to learn how to sell beautifully. True experts are not just good at buying, but ruthless at selling.

Based on these years of practical experience, I’ve summarized a profit-taking and stop-loss system suitable for working people—after all, not everyone has the time to watch the charts every day:

**Profit Lock-In: Staged Selling**

Suppose a coin rises from $1 to $2; immediately sell 30% of your position. This step is crucial, as it effectively insures your principal. The subsequent ups and downs become easier to handle psychologically.

If you still believe in the coin, and the price pushes to $3, sell another 30%. By then, a good portion of your profit is safely in your pocket.

The remaining 40% of the position is managed with a trailing stop. The rule is simple: start from the highest point, and once it drops 15%, sell everything. This way, you avoid chasing the top and also prevent watching profits evaporate.

**Loss Prevention: Ruthless Execution**

Set a stop-loss at -10%, like fastening your seatbelt before driving. Never trust the hope of a "rebound"—the market won't change direction just because of your confidence.

My rule for single-loss limits is 5% of the total principal. Violating this bottom line means handing your chips over to the market. Once the principal is gone, you can't play the game of waiting for another 10x rise.

Don’t be afraid of missing the perfect sell. In the altcoin market, opportunities are never lacking; what’s missing are those who stay alive. Surviving the bear market to see the next bull run is the biggest way to profit.

After all these years, I’ve seen that none of the investors who make it out unscathed rely on luck. They all discipline themselves to lock greed in a cage.
