Eight years of navigating the crypto world, and the deepest scar comes from that wave of ADA in 2017.

Starting to build positions from 0.03U in batches, three months later soaring to 1.2U, with unrealized gains approaching 40 times. During that time, I completely lost myself—waking up every day to check my balance, even memorized the address of the Porsche 4S dealership, truly believing that financial freedom was just around the corner. And what happened? I didn’t sell a single coin.

ADA plummeted back to 0.2U, turning what was once huge profits into bubbles, and the Porsche dream turned into the reality of a used car. I can still feel that pain. It was then I realized: buying relies on luck, but selling is the real skill.

Many people ask why my current operations are so stable. It’s all lessons learned from losing real money. Later, I developed a simple method especially suitable for working professionals—

**Taking profits like this: stage by stage, don’t chase the peak**

When the coin doubles, sell 30% to recover the principal. When it triples, sell another 30% to lock in the main profits. The remaining position is set with a trailing stop—if it retraces 15% from the high, automatically close out. In short: those who aren’t greedy run the fastest. Opportunities in the market are always there.

**Setting stop-loss like this: 5% is the limit, no bargaining**

Any trade losing 5% immediately exits; set the stop-loss order in advance—like fastening your seatbelt when getting in the car, it’s a mandatory action. Last month, after applying this stop-loss, that coin doubled in value, and friends joked I was too cautious. But three months later, it went to zero. The ones who survive are always disciplined.

In the crypto world, it’s not about who makes the most money in a moment, but who can last longer. I’ve seen people with six- or seven-figure unrealized gains, eventually return all their money to the market. They either don’t understand the technology, or they’re reluctant to sell, can’t cut losses, or refuse to admit mistakes. The most expensive thing in this market is never the strategy, but self-discipline. Only by executing rules like running a program can you truly take your money out.
