Eight years ago, I took tens of thousands of yuan and plunged into the crypto market. Luckily, I caught the bull market, and my account multiplied several times. Back then, I truly felt like I’d found a printing machine.

Then one liquidation wiped everything out overnight—years of money gone in a single night. Later, I restarted with the last bit of capital I had, and I completely quit the “all-in, put it all on the line” mentality.

Now when I trade, I follow a few hard rules:

If I can’t make sense of the market, I don’t touch it—I’d rather stay in cash and wait;

When I’ve made the amount I’m satisfied with, I exit—don’t get greedy, or the final profits will turn back into losses;

As soon as good news drops, be alert. Before major news comes out, reduce the position you’re holding;

For long-term trades, keep exposure light. For short-term trades, you must wait for the signal before acting;

After a big surge, if it turns into a slow, dragging grind downward, and after a crash you get a weak rebound—don’t try to bottom-fish, and don’t stubbornly hold on;

If you’re wrong on direction, admit it, set your stop, and leave.

Over the years I’ve learned this the hard way: what truly makes people lose so badly they can’t get back up is never just getting one or two calls wrong—it’s getting a call wrong and still refusing to let go.

Only today do I understand—technique determines whether you can catch opportunities; position sizing determines whether you can survive; and emotion and discipline decide whether you can stay at this table.
