The most painful yet most valuable lesson in these 8 years—back in 2017, when ADA was still at 0.03U, I made a bold move and within just three months, it skyrocketed to 1.2U, with an unrealized profit close to 40 times. During that period, I was extremely inflated, checking my account balance first thing every morning to see how many zeros had been added, even going as far as visiting a Porsche 4S dealership.

But here’s the key: I didn’t sell a single one.

Later, ADA dropped to 0.2U, and the previous huge profits evaporated instantly. The Porsche I dreamed of suddenly turned into a used car, and I will never forget that feeling. It was at that moment I realized that trading cryptocurrencies isn’t just about buying—buying is luck, but selling is true skill.

Many people think my current stability comes from strong skills, but honestly, it’s a strategy I learned after many lessons. This method sounds simple and silly, but it has been proven countless times at a great cost, especially suitable for office workers and friends who don’t have time to watch the market:

**Profit-taking**: I never gamble on what the top is. The operation is straightforward—sell 30% after doubling, to recover the initial investment immediately; when it triples, sell another 30% to lock in the main profits; the remaining part is set with a dynamic stop profit, and if it retraces 15% from the peak, I close the position entirely.

**Hardcore stop-loss**: Never lose more than 5% on a single trade. If there’s a problem, run immediately—faster escape means safer. After each purchase, my first reaction is to set a stop-loss order, like fastening a seatbelt on my account. Last month, I decisively stopped a loss on one coin, and afterward, that coin doubled in value. My friends laughed at me for being too conservative, but three months later, it went to zero—ultimately, I was the one laughing.

The crypto market has never been about who can get rich overnight; it’s about who can survive longer. I’ve seen too many people make six or seven figures, only to lose every penny and walk away empty-handed. It’s not because they lack analysis skills, but because they’re unwilling to sell, stubbornly hold through stop-losses, and refuse to admit mistakes. The most expensive thing in this market is never advanced technology, but self-discipline—strictly following rules like a machine to truly put profits into your pocket.
