After years of struggling in the market, I've seen too many newcomers repeatedly make the same mistakes. Today, I will break down a few life-saving operational principles. I don't expect you to make a lot of money, but at least it will help your account survive longer.

**Let's start with the most heart-wrenching phenomenon**: with 20,000 yuan opening a position, a 5% rise makes you hurriedly take profits, fearing the cooked duck will fly away. What happens next? You watch it rise by 50% right before your eyes. Will you be smarter next time? No, you become greedier, stubbornly holding on until it drops back to your principal before you're willing to cut losses. This habit of "quickly wanting to earn small amounts, but unwilling to run from big losses" is basically the number one culprit of losses. What you should really remember is: don't fidget over a few points of fluctuation, but when there's a major risk signal, you should get out quickly.

**Let's talk about the matter of selecting coins**. The more flashy altcoins and newly launched coins should be avoided as much as possible. Focus on mainstream coins that have already dropped significantly and are starting to stabilize. Note that what is meant here is "stabilizing", not for you to guess the bottom or catch the bottom—just take a 10% position to test the waters, and wait until the stabilization signals are clear before proceeding. Although it may seem clumsy, at least it won't lead you to a zero-value trap.

**Regarding the timing of adding to your position**, don't blindly follow those who suggest catching the bottom online. Wait until the trend is clearly upward, and then add 20%-30% to your position during a pullback, even if the cost is slightly higher. Compared to being stuck halfway up the mountain, this minor cost difference doesn't matter at all. Remember this: the trend is always a hundred times more important than the specific entry point you think you've captured.

**The last and most crucial point**: Every time there is a surge, withdraw half of the profit along with the principal! Let the remaining profit continue to roll in the market, rise and fall as it pleases. The money you actually earn is the one you secure; don't foolishly give back the profits you've already obtained to the market.

These principles are indeed easy to articulate, but not many can truly implement them. The cryptocurrency space has never been about talent; it's all about discipline and restraint. Following these guidelines can at least help you avoid most pitfalls.
