#ETH走势分析 Last year, I helped a friend manage his account. With a principal of 3,000U, we doubled it on the very first trade. He excitedly contacted me in the middle of the night, saying, "Making money is so easy!" I told him, "You've seen the easy part. The hard part starts now."

That statement proved true. The next day, he heard some "insider tip" and threw all his funds in at once. In less than ten minutes, the account shrank to 3,300U. He panicked and asked me what to do. I replied with just four words: "Calm down first."

Over the next three months, he truly grasped the core of trading—not how many candlestick patterns or technical indicators you learn, but understanding this: after making money, you must control your impulses; after losing money, you must stay rational. That's the real key to survival in crypto. In the end, he managed to grow the account from 3,300U to 90,000U.

**The half hour after making a profit is when you're most likely to crash**

This is where many people fail: as soon as their account is in the green, their guard drops and they throw out their original plan. Mature traders, on the other hand, immediately reduce their positions when making money to lock in profits and don't let emotions hijack their judgment.

**Live by rules, not by feelings**

My approach is actually very rigid:

- The maximum for a single trade is capped at 15% of total funds, with stop-loss set at 2%
- For major coins like $BTC and $ETH, I take half off the table after a 5% profit and let the rest run
- I stick to a fixed weekly trading frequency, no matter how tempting the market looks—never break the rules

This system may sound boring, but it could save your life. It keeps you out of the vicious cycle of "huge gains followed by huge losses." Opportunities are always there, but only those who survive to see the next one truly win.

Have you ever experienced losing control after making money? Take a moment to reflect—is the market really that complicated, or is it your mindset that's not ready? True experts never expect to catch the exact bottom every time. What sets them apart is that they hold firmly to their rules amid emotional waves. It's that simple.
