#美国非农就业数据未达市场预期 Cardano (ADA) those years of wild surges and crashes, I’ve tasted both sweetness and bitterness from them.

I still remember those crazy days in 2017. Work stress was high, income was modest, and a colleague casually said, “This Japanese Ethereum project is only 3 cents per token,” and I impulsively invested all my wedding savings of 30,000 yuan.
As a result, ADA shot up like it was powered by a rocket engine, soaring from $0.03 to $1.2. In three months, my account skyrocketed from 30,000 to 1.2 million. Those days, I couldn’t sleep well, afraid of missing a rise, and I even took my phone to the bathroom.
But good times didn’t last long. The market suddenly turned, and ADA plummeted like a dive, dropping to $0.2, and my paper profits evaporated by 900,000 yuan instantly. At that moment, I truly understood what “wealth on paper” means.
That pain taught me a lesson, and I decided to change my strategy. I developed a practical step-by-step profit-taking plan:
**Take 30% off after doubling** — secure the principal first, and let the remaining profit run. When it doubles again, sell another 30%, and this money can be directly given to family members for peace of mind. For the remaining position, set a trailing stop-loss: if the highest price drops by 15%, automatically close the position. Even if I miss the continued rise, I can at least protect the main gains.
**Stop-loss must be firm** — if a single loss reaches 5% of the total funds, exit immediately. Many people hesitate to cut losses, turning small losses into big pits.
I later tested this method on FileCoin (FIL), from $8 to $90, with solid returns.
The crypto market is constantly changing, but one hard truth remains: if the principal is gone, everything is useless. No matter how optimistic you are about a coin, you must leave yourself an exit. More people know how to buy than how to sell, which is why most get stuck here.
Survivors and profit-makers in this market are never those who gamble everything on a single shot for tomorrow, but those who know when to take profits and cut losses in time. Step-by-step profit-taking may seem simple, but it’s actually a risk management logic based on data.
