"Three days to lose half a month's salary, does this money fall from the sky?" Seeing the cries of beginners, I am reminded of my own bloody experience eight years ago.

At that time, I entered the circle with 20,000 yuan, completely a bagholder—chasing gains and cutting losses, doing everything, chasing hot spots and going all-in with leverage as if it were free. And the result? The account shrank from 20,000 to 8,000 directly, and at the worst, I really wanted to smash my phone and quit this devilish game.

After lying down for three days, I finally understood a painful truth: in the crypto market, "surviving" is always more valuable than "how much you earn." Without principal, what’s the point of doubling? After that, I devised three "fund safety locks," zero liquidation in four months, turning 20,000 into 100,000. All the essentials are here, beginners must see through:

**First Lock: Always leave an exit for your position, going all-in is a death sentence**

No matter how tempting a good opportunity is, you must restrain yourself. I never allocate more than 30% for the initial position. Last year, during a bottom-fishing dip, I invested 30% first to verify the direction, then added in stages once the trend was confirmed. What’s the benefit of doing this? Not missing the market opportunity, and still keeping bullets for a comeback. Think about it—opportunities are always there, but if your principal is gone, it’s really gone.

**Second Lock: Set stop-profit and stop-loss firmly, greed is poison**

I used to be trapped by greed—earning money but reluctant to sell, ending up losing 2,000 yuan. Now, my rules are very strict: stop-loss no more than 4%, take profit set at 8%-12%, and execute immediately once hit, without delay. Sounds like small gains? But the risk of liquidation is also reduced. Earning less is always better than losing everything.

**Third Lock: Don’t touch what you don’t understand, don’t be drowned by noise**

In early years, I followed some KOLs chasing so-called "concept coins," and lost half in three days. The lesson was deep. Now I only buy projects that I can understand from whitepapers, have a real team backing, and clear real-world scenarios. Better to miss ten opportunities than to step into one big pit.

The data from these four months is the best proof—56 trades, 68% success rate, net profit of 80,000 yuan. I never chase hot spots, never gamble all-in, trade more when the market is good, and stay in cash during sideways periods. For beginners to survive here long-term, the first lesson is not how to get rich quickly, but how to stay alive.

One heartfelt final word: the market is always there, opportunities will come again. As long as you haven't been liquidated, you haven't truly exited. In this game of waves and sands, surviving until the end makes you the winner.
