#数字资产市场动态 has been navigating the crypto market for six years, and there's one moment I will never forget—the frenzy of altcoins in 2019. I bet on $ADA, buying in several times starting at $0.03. In less than three months, it shot up to $1.2. The account balance increased nearly fortyfold, and I even started thinking about using that money to pay for a full mortgage in the city.

The first thing I do every morning is check the market, watching those zeros keep climbing. That feeling... it can make you float. But then, I made a fatal mistake—being too greedy and not decisively hitting the sell button.

Soon after, ADA experienced a cliff dive, crashing down to $0.2 in one go. The unrealized gains were like water splashed out—they could never be recovered. Eighty percent of the profit evaporated instantly. That house dream? It vanished into thin air.

This huge loss taught me a harsh truth: in the crypto world, learning how to buy is just the basics; the real watershed is—knowing how to sell.

Later, I developed a trading discipline based on real money, especially suitable for those who can't monitor the market all the time.

**For taking profits, I use a staged reduction method**:
Suppose a coin rises from $1 to $2, I sell off thirty percent first, basically recouping my principal. This way, I don’t feel bad about the remaining position, and I can stay calm. When it rises again to $3, I continue to reduce another thirty percent. The remaining forty percent, I set a trailing take profit—if the price drops more than 15% from the peak, I close everything with one click. This way, I can enjoy the main upward trend without giving back all the gains.

**For stop-loss, it’s even simpler and more brutal**—a strict rule: the loss on a single trade must not exceed 5% of total funds.
After opening a position, I immediately set a stop-loss at -10%. It’s like insuring every trade. Don’t worry about missing opportunities—there are plenty in crypto. But once your principal is gone, you lose the chance to turn things around completely.

In these six years, I’ve seen too many stories of overnight riches, but more often, I’ve seen people lose everything on rollercoasters. Those who manage to walk away with profits are never lucky—they’re the ones who strictly follow trading discipline.

The logic of making money in crypto isn’t complicated; what’s complicated is whether you can control your hands. I hope you can learn something from others’ stories.
