At three in the morning, I collapsed in front of my computer, the candlestick chart stabbing into my heart like a blade. The 8,000 Tether in my account had become 3,200. Dark circles etched into my face, and all I gained from staying up all night watching the market was regret.

Back then, I thought I was clever, believing I could beat the market with my judgment. Chasing hot trends, speculating on concepts, going all-in on new coins— I didn’t miss any of the hot spots. It wasn’t until reality repeatedly slapped me in the face that I realized—the crypto world isn’t a playground for "smart people," but a cash machine for "disciplined individuals."

The lessons learned with real money, I’ve summarized into three safest ironclad rules.

**Ironclad Rule 1: Only engage with "veteran players"; even if new concepts seem tempting, stay away**

I used to be a "curiosity seeker." My watchlist was filled with various tags—Metaverse, Web3.0, "next-generation public chains"—whatever concept was hot, I followed the trend. Later, I heard experts say to diversify investments, but I misunderstood and thought it meant buying more altcoins. As a result, I chased a new project combining "AI + blockchain," and as soon as I invested, the project team ran off, losing half a month’s salary.

Now, my watchlist is very clean: Bitcoin, Ethereum, and a few mainstream coins in the top ten by market cap. Some say I’m too conservative, but I know that these "veterans" who have weathered multiple bull and bear cycles are like that ten-year-old shop at the neighborhood entrance—no matter how bad things get, they won’t suddenly close and run off with the money.

From time to time, the circle whispers about some "new rich" who triples their investment in three days, and fans DM me asking if they should jump in. My answer is always—the seemingly rapid wealth often leads to the fastest margin call.
