Do you still remember those days when you survived on instant noodles? I still haven't forgotten.

It was July 2015. Back then, Bitcoin was only selling for 2,300 yuan each. I almost poured all my savings into it, buying 12 at once, and the remaining change I casually used to buy some small altcoins. My colleagues in the office looked at me as if I were a fool, saying I was playing "virtual pyramid schemes."

And what happened? A year later, Bitcoin rose to 8,000. My principal tripled. By the time of the 2017 bull run, it was even more outrageous—Bitcoin skyrocketed to 120,000 yuan, and at the peak, my assets reached over 27 million.

But I just couldn't hold onto that money. The 2018 bear market cut everything in half, and during the LUNA crash in 2022, I lost 1.8 million in a single day. Over these ten years, the whole process has been like a roller coaster—without a seatbelt.

However, after all this tossing around, I finally summarized some rules, which helped me stabilize my footing.

**First Rule: Segment your bull market entries, plan your bear market investments**

I observed many people and found that the biggest mistake everyone makes in a bull market is greed. Prices go up, and they want them to keep rising. But when the market starts falling from the high point, they begin to regret—why didn't I sell earlier?

In 2017, I set a strict rule for myself: as long as my assets doubled, I had to sell 10%. The benefit of this approach is that it allows you to truly lock in profits and avoid missing out on subsequent opportunities due to panic. Thanks to this rule, I cashed out over 4 million yuan near the historical high, which later became the down payment for my house.

In a bear market, the approach is completely opposite. I set a rule: regardless of the situation, I must invest in Bitcoin on the 15th of every month, without looking at price movements. The beauty of dollar-cost averaging is that it helps you bypass emotional hurdles. When the market is in panic, you can buy chips at very low prices.

Data shows that even if you started dollar-cost averaging after Bitcoin hit its all-time high in November 2021 and continued to this day, your account would already be in profit. What does this mean? It proves that as long as you don't go all-in at an absolute high, dollar-cost averaging can save you.

**Second Rule: Always prioritize risk awareness**

The deepest lesson over these years is: don't put all your eggs in one basket. I learned this the hard way—if a certain coin suddenly crashes, it can wipe out millions of your account value instantly.

My subsequent strategy is this: keep core holdings in large-cap assets like Bitcoin and Ethereum, with a proportion set at 60% to 70% of total assets. The remaining 30% is for trying out new projects. Even if they fail, your principal won't be lost too much. Another key point is to always keep 10% of your funds in cold storage, not touching the market, just as an emergency reserve.

**Third Rule: Regular review, don't let emotions dictate decisions**

Every quarter, I review my account data—see how each asset is performing and whether my portfolio structure still makes sense. This habit has saved me several times—many times, it was because of timely adjustments that I avoided further pitfalls.

For example, if I buy a coin that keeps falling for three months without rebound, I consider switching to a different project. Not because I can predict the market, but because regular review forces me to stay rational and not be driven by short-term emotional swings.

These ten years of experience tell me that in crypto markets, those who make money are often not the most technically skilled but the most emotionally stable. The method isn't complicated—stick to discipline, control risks, and review regularly. Doing simple things repeatedly can lead to different results.
