The red and green candlesticks on the screen are dancing, while my heartbeat has long become their background sound.

That summer six years ago, in the rented room, I was accompanied only by that constantly flashing screen. When ETH surged from 1800 to 2400, I unhesitatingly bet all my funds of 8000U. At the moment I clicked 'buy', all I could hear was the sound of my own rapid heartbeat.

In the next seven days, the account's floating profit is 6000U, and I feel like I am on top of the world. I even turned off the profit-taking reminder, firmly believing in the fantasy of 'selling when it hits 3000', and even the aroma of hot pot wafting through the window cannot make me step away from the screen.

However, a news from the Federal Reserve about interest rate hikes changed everything. ETH fell back to 1900 in half a day, and I watched my dazzling profits disappear, yet I was still trapped by the obsession that 'mainstream coins will definitely rebound.'

In the end, the account balance froze at 300 U. I squatted on the cold ground, gnawing on a cold flatbread, my throat tightening. At that moment, I realized: no matter how strong the coin, it cannot overcome the greed deep within human nature.

Lessons learned repeatedly.

The market never hesitates to teach lessons to those who think they are smart. An NFT I bought for 15,000 U rose to 32,000 U, but due to greed, I didn't sell in time and ultimately had to cut my losses; during BTC swing trading, I personally canceled my stop-loss and stubbornly held on until my assets were halved.

These painful experiences finally forged three life-saving iron rules.

Three trading iron rules exchanged for real money.

Diversifying positions is leaving a way out for your future self.

Now, my capital allocation strictly follows these principles: 35% as a stabilizer stored in a cold wallet in BTC, which is the ballast to withstand bull and bear markets; 45% as the main force invested only in mainstream coins like ETH and SOL, never touching junk coins; the remaining 20% as emergency funds, never fully invested, maintaining a sense of breathing.

No matter how crazy the market is, I no longer bet all my hopes on a single gamble. Position management is the first rule of survival.

Profit only becomes yours when it enters your pocket.

I will always remember the scene last year when ETH surged from 1900 to 2500. The account profit was 120,000 U, but this time I did not repeat the same mistake and immediately withdrew 42,000 U to save as a fixed deposit. Then ETH pulled back to 2100, but I felt an unprecedented calm.

The numbers on the screen always belong to the market; only those in the bank account are yours. Unrealized gains are just part of the process; securing profits is the result.

Stop-loss is drawing a line between yourself and the loss of control.

Now, my stop-loss discipline is as strict as iron: if a single loss exceeds 2%, exit unconditionally; if monthly drawdown exceeds 5%, take a mandatory break.

I once firmly believed that 'mainstream coins resist falling,' until I lost 3000 U in a single position and woke up. Now, stop-loss feels as natural as breathing to me—acknowledging small mistakes is to avoid irreversible disasters.

Final thoughts.

This market never lacks miracles; what it lacks is the clarity of not being greedy, not holding on, and not being anxious after climbing out of the abyss.

The candlestick chart can show price trends, but it cannot measure the depths of human nature. Behind each candle, there is a fierce tug-of-war between bulls and bears, as well as a struggle with our inner demons.

Have you ever had moments in the middle of the night staring at the screen, feeling anxious yet stubbornly holding on?

The essence of survival lies not in seizing every opportunity but in avoiding those deadly traps. This is the most important lesson six years of trading has taught me: pay attention to Ake, let him bring you more first-hand information and cryptocurrency knowledge; accurate points will become your navigation in the crypto world, and learning is your greatest wealth!#巨鲸动向 #加密市场观察 $ETH
