What does the Candlestick at three in the morning look like? I know it all too well. It's not because I was excited and couldn't sleep after seizing an opportunity, but because I watched my account fall from 580,000 to 190,000, that kind of chilling feeling can keep one awake all night.

Having been in this industry for eight years, I have seen too many stories. There are plenty of people who made a fortune riding the trends, but how many can actually keep their money? You won't find one in ten. The harshest part of this circle is not that you can't make money, but that you can make money and yet can't hold onto it—this barrier directly eliminates 90% of the players.

In the market wave of 2020, my buddy Lao Zhou is a living example. He started with a capital of five thousand and in less than half a year, he was close to a hundred thousand. When we met offline, I told him, let's withdraw a portion first, even if it's just to secure 20%. How did he respond? "You're thinking too small, brother. This is just the beginning. Let's talk again when I hit four hundred thousand."

Later events were predictable. Two months later, the market turned downward, and those wildly rising coins began to plummet. From over ninety thousand down to fifty thousand, he said "normal correction, hold on"; when it fell to thirty thousand, he was still stubbornly holding on; finally, when his account only had a few hundred left, he uninstalled the trading software in front of me, leaving behind a remark "this money is too damn torturous to earn," and he never touched this industry again. That experience became a psychological shadow for him, and he didn't even want to mention it.

To be honest, I have also fallen at this hurdle myself. The hardest part in the crypto market has never been how to make the first profit, but whether you can harden your heart and press that take profit button after making money. This principle often has to be paid for with real money.
