#美国就业数据不及预期 My sister had a big setback in the crypto world last year, losing 360,000 yuan.

During that time, she was completely disoriented, locked herself in her room, and didn’t go out for three days. When we met again, her account only had 3,600 USD left, but her eyes were surprisingly clearer.

I was deeply impressed by what she said: "Instead of waiting to die, I might as well try with this little capital." And guess what? She really turned things around with that 3,600 USD—growing from a few thousand to 100,000, not only filling the pit but also earning an extra 30,000.

Later, during casual conversations, she summarized that all these were "lessons learned with money."

The biggest change was in trading discipline:

Single position size should not exceed a quarter of total funds; if floating loss reaches 10%, cut immediately without hesitation; abandon the idea of predicting tops and bottoms, follow the trend; take profits and withdraw the main part, leaving a small portion to continue rolling.

She often says: "Taking it slow is always better than going to zero overnight. As long as the principal is there, opportunities will come."

Actually, she doesn’t have any special talent, she just learned to fight her own greed. Later, she also helped friends, turning 2000 USD into nearly 10,000, and repeatedly advised others to cut losses in time.

Over these two years, I’ve gradually realized that cryptocurrencies like $ETH and $BTC are never short of market movements. What’s truly scarce is self-control—those who survive the longest in the market are often not the ones earning the most, but those who know how to protect their principal.

Many people are not lacking effort; they just need a set of principles forged through personal experience. In the crypto world, there are no absolute dead ends; what can truly save you is a trading philosophy earned through blood and sweat.
