I am the kind of trader who crawled out of blood. Seven years ago, during that winter, I took a big hit on a contract—8 million in principal evaporated in an instant, and I still remember that feeling of helplessness vividly. It was precisely because of that lesson that I later figured out the most fundamental and important rule in the crypto world: surviving long enough is worth a thousand times more than short-term riches.

In the spring of 2025, I turned 1,141 yuan of capital into a 2.15 million profit within 30 days. It sounds exaggerated, but there are no black magic behind it—just the "clumsy methods" refined over the years. Today, I will lay out the core ideas.

**First Key Point: Only eat the thickest meat, don’t chew on toxic bones**

I have seen too many people mesmerized by the stories of overnight riches from altcoins, only to end up losing everything. The fluctuations of those coins are completely unpredictable, with obvious signs of market manipulation. Essentially, it’s just a playground for whales to harvest retail investors.

I set a strict rule for myself: only trade BTC and ETH with high sell-high, buy-low strategies, and ignore everything else. These two coins are the ballast of the crypto market. Even if caught in a short-term trap, there’s no need to fear—they always have opportunities to turn around during a bull cycle. Last year, many followed the trend and speculated on obscure coins, which rose slowly and fell quickly. I instead stuck to these two mainstream coins and ultimately gained a steady increase of over 50%.

**Second Key Point: Position size and leverage are like a seesaw—if one side is high, the other must be low**

I usually use 10x leverage, combined with 2 to 3 layers of position size (total capital allocation of 20%-30%). Once the position exceeds 30%, the leverage must be reduced to below 15x. When it reaches 40%, leverage must be cut to within 5x. This is a lesson learned at the cost of liquidation: leverage and position size are always inversely related. If you want one side to be heavy, the other must be light.

Another critical detail—stop-loss. Many people treat stop-loss as a decoration, but in fact, it’s the real safety belt. I set a stop-loss on every trade—not as psychological comfort, but as a rule to protect myself.
