In 2018, I was staring at the screen in a rental house in Shenzhen—Bitcoin skyrocketed from $18,000 to $19,000, and an initial investment of 300,000 soared to nearly 3 million. I was so excited those days that I couldn't sleep, my mind full of "The crypto world changes destiny," feeling like I'd never have to worry again.

However, three days later, the market crashed, profits evaporated, positions blew up, and by Christmas, I was left with less than 600,000. At that moment, I realized that what truly destroyed me was the most toxic belief: "Just wait a bit longer and I'll break even."

After eight years in the crypto world, I exchanged real money for three hard-learned lessons:

### 1. Leverage is a knife, not wings

I once used 20x leverage on Ethereum, making 400,000 in a day, staying up all night in excitement. That feeling of soaring led me to mistakenly believe I was a genius. It wasn't until May 19, 2021, when I lost 600,000 in two hours and my account went to zero that I realized: leverage amplifies not judgment, but greed.

Now, my iron rule remains: leverage should not exceed 3x, and single contract positions should not exceed 5%. Want to dance on the edge of a cliff? First, weigh whether you can withstand the storm.

### 2. Don’t look for treasures in a casino

I once heavily invested in a "domestic Ethereum," entering at 250,000, peaking at 1,500,000 but never selling a share. The project team shouted revolution and talked consensus every day, but now the price is less than $0.001, resulting in total loss.

Later, I completely adjusted my positions: 85% in BTC+ETH as ballast, and 15% in altcoins as entertainment funds. Dreams can exist, but don't bet your entire fortune on "castles in the air."

### 3. Stop-loss is the last dignity

Now I set an 8% hard stop-loss for every trade, executing it without explanation or hesitation. This rule has saved me countless times—stop-loss is never about being timid; it's the only way to survive.

In the crypto world, those shouting "value investment" are mostly retail investors unwilling to cut losses after being trapped. Want to double your investment? First, ask yourself: If your account goes to zero tomorrow, can you still calmly enjoy a hot pot meal? If yes, continue; if no, stop.
