In April 2022, during that wave of the market, I used 25,000 yuan as principal to short LUNA at $98. Overnight, my account skyrocketed to 750,000. I was sitting in front of the screen, palms sweaty—thinking I was finally turning my luck around.

And what happened? Greed is like a timed bomb buried deep inside. I didn't take profit as planned; instead, I got impulsive and decided to go all-in for the bottom. When that "LUNA zeroed out" push notification popped up, my phone slipped from my hand, and I was too exhausted to even curse.

My account went from 750,000 to a small fraction. That feeling, I really can't describe. But I didn't give up. I dug out a gold bracelet I bought with a year's salary and sold it for 18,000, deciding to start over. This time, it was different—I abandoned the fantasy of "getting rich overnight" and began to follow disciplined trading.

**Building Positions Must Pass "Four Barriers"**

Since then, I no longer trade based on feelings. Before moving funds, I check four things: weekly trend, volume signals, on-chain fund movements, and main force holdings. It sounds dull, but this dullness has saved me many times.

When TRB was sideways around $12, I spent three days going through these four barriers. No anomalies, the funds were clean, so I entered with a small position. During that market wave, many got caught by false breakouts, but I avoided it.

The essence of trading isn't about guessing what the market will do in the next second, but understanding through the logic of accumulation and release. Short-term rises and falls are noise; real opportunities are hidden in the data.

**Review and Don't Panic Sell During Losses**

TRB later fell 28%. That was tough, but I didn't panic and sell off. Every evening after work, I studied until dawn, drawing candlestick charts by hand on my notebook, calluses forming on my fingers.

I found that the main force didn't completely withdraw, and the weekly support was still holding. What does this mean? It means this isn't a deadly plunge but a shakeout. Once I confirmed this, I even added to my position gradually during the decline.

Later, when TRB rebounded, this trade gave me nearly 3 times the maximum profit. But the key isn't how much I earned, but that I learned to think during panic, instead of running with the panic.

**Profit-taking Shouldn't Be Arbitrary Like Stop-loss**

This last point is also very important: many people set strict stop-losses but become vague at take-profit levels. That logic is backwards.

My approach is: when making money, take profits in stages—lock in part of the gains first, let the rest run. This way, I avoid repeating disasters driven by greed, and I keep the opportunity to catch big moves. That’s exactly how I handled the TRB trade—stayed steady during a 28% dip, then exited in three stages during the rebound, each target set in advance.

From zeroing out at 750,000 to gradually restoring my account to five figures, this process wasn't filled with dramatic stories but with daily dull checks and discipline. But it's this dullness that made me a true trader.

Greed is indeed a trap; discipline is armor.
