#以太坊行情解读 After eight years of struggling in the crypto world, I have witnessed many magnificent market fluctuations and experienced quite a few moments of losing control over my mindset. The most profound memory is still anchored in that madness of 2017.

At that time, altcoins were performing miracles one after another, and $ADA was one of them. I started accumulating at $0.03 in batches, and within three months it soared to $1.2—my account balance directly multiplied by 40 times. The first thing I did every day was check the market, watching my asset value grow larger and larger, and I even started planning how to use this money to invest in real estate.

So what? I didn't take action.

ADA subsequently entered a cliff-like decline, plummeting back to $0.2. The unrealized 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 who can buy, but very few actually make money. The difference comes down to one word: sell.**

The profit-taking and stop-loss system I have summarized over the years has been gained through real money. It is especially practical for retail investors who cannot monitor the market all day.

Assuming a coin rises from $1 to $2, I will first sell 30% of my holdings. This step is crucial – the principal is basically recovered, and my mindset becomes instantly relaxed; the remaining fluctuations are not so anxiety-inducing. I will continue to wait until it reaches $3, then reduce my holdings by another 30%. For the final 40%, I will manage it with a trailing stop loss, automatically clearing everything if the price falls back 15% from the peak. This way, I won't miss the main upward trend while also firmly locking in profits.

There is one 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 of missing out on some small market movements—there are plenty of opportunities in the crypto world, but if you lose all your principal, you'll completely lose 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 ups and downs. In the end, those who can exit with profits are almost always the ones who execute their discipline the strictest. It's not that their coins are chosen particularly well, but rather that their respect for risk is deep enough.

The market is right there; the key is whether you can live long enough to wait for your own wave of opportunity.
