I recently heard a story from a friend that really hit home. She invested in a small coin, watching it drop from a high of $11 all the way down to $1.6. She couldn’t take it anymore and sold. And what happened next? It shot up to $15. The feeling, as she put it, was like "my intestines are all regret."

Actually, after being in the crypto market for a long time, you’ll find these stories everywhere. "Sold and it rises, bought and it falls," "scared by volatility and ending up empty-handed"—these are not jokes but real tragedies playing out.

So where’s the problem? Honestly, it boils down to two words: **emotion**. Many people think they lose money because they lack technical analysis skills or good strategies, but the real reason is emotional out of control. Greed when prices go up, wanting to earn more; fear when prices fall, worried about further losses. Under the influence of these emotions, they make mistake after mistake.

Take my friend’s case: the first mistake was being blinded by greed at $11 and not taking profit in time. The second was even worse—at $1.6, she was overwhelmed by fear and blindly cut her losses. The whole process was just market-driven, with no rational judgment at all.

After years of navigating this market, I’ve summarized a core rule: **Control your emotions, respect your cognition**. It sounds simple, but actually doing it is very hard. Here’s a practical tip—**keep a trading journal**. Record each trade: why you entered, why you exited, how much you invested, and your mental state at the time. Over time, you’ll see your emotional patterns clearly and truly learn how to coexist with your greed and fear.
