#以太坊行情解读 Eight years of navigating the crypto world, I have witnessed countless grand market waves and experienced many moments of losing control over my mindset. The most profound memory still anchors back to that madness in 2017.

At that time, altcoins were performing miracles one after another, and $ADA was one of them. I started accumulating in batches from $0.03, and within three months, it soared to $1.2—my account balance directly multiplied by 40 times. The first thing I did every day upon waking was to check the market, watching my asset value grow larger and larger, and I even began to plan how to use this money to invest in real estate.
What was the result? I didn't take action.
ADA subsequently entered a cliff-like decline, crashing back to $0.2. The floating profits evaporated in an instant, and the once 40-fold returns dwindled to less than 5 times. The dream of buying a house also vanished into thin air. That lesson was heavier than anything else.
**In the crypto world, there are many people who can buy, but very few actually make money. The difference lies in one word: sell.**
The profit-taking and stop-loss system I have summarized over the years has been earned with real money. It is particularly useful for retail investors who cannot monitor the market all day.
If a coin rises from 1 dollar to 2 dollars, I will first sell 30% of my holdings. This step is crucial - I have basically recouped my principal, and my mindset becomes relaxed instantly; the remaining fluctuations are not so anxiety-inducing. I will continue to wait until it reaches 3 dollars, and then reduce my holdings by another 30%. For the final remaining 40%, I will use a trailing stop to manage it, automatically clearing everything if the price drops 15% from the peak. This way, I won't miss out on the main upward trend, while also securely locking in profits.
There is another iron rule that I never violate: **the maximum limit of a single loss is set at 5% of the total principal.**
Every time I open a position, I immediately place a conditional order with a stop loss line at -10%, without exception. Treat it as insurance for trading. Don't be afraid to miss out on some small market movements—there are plenty of opportunities in the crypto world, but if you lose all your capital, you will have completely lost the chance to recover.
Over the past eight years, I have seen too many cases of overnight wealth, only to turn around and see them all exit during the roller coaster of fluctuations. In the end, those who can leave with profits are almost always the ones who execute discipline the most rigorously. It's not that their coin selections are particularly good, but rather that their respect for risk is deep enough.
The market is right there; the key is whether you can survive long enough to wait for your own wave of opportunity.
