#数字货币市场洞察 There’s a guy from Fujian who called me last night in tears—at 3 a.m., his 6,000 yuan account was wiped out completely. When I asked what happened, I found out he dumped 5,800 yuan in at once, without even setting a stop loss. Isn’t that just asking for trouble?

Honestly, a lot of people get this wrong: leverage isn’t the real culprit—position sizing is.

Let me break it down for you. Suppose you have 800 yuan in capital:
- Scenario A: You put 750 yuan into a 5x leveraged trade. If the market goes just 6% against you, you’re done—Game Over.
- Scenario B: You only use 75 yuan with the same 5x leverage. The market would have to move against you by 86.7% before you’re in real trouble.

See the difference? Same 5x leverage, but your risk tolerance is over 12 times higher. That Fujian guy went all-in with 96.7% of his money, using 5x leverage, and a 3% price swing wiped him out. That’s not bad luck—he dug his own grave the moment he placed the trade.

I’ve made plenty of mistakes myself, but I eventually came up with three survival rules:

**Rule #1: Never put more than 7% of your total funds into a single trade.**
If you have a 6,000 yuan account, only use up to 420 yuan per trade. Even if you hit your stop loss, it won’t hurt too much.

**Rule #2: Keep single-trade losses under 1.1%.**
For example, with a 420 yuan trade at 5x leverage, set a 1% stop loss. If you lose 8.4 yuan, just get out. Don’t think stop losses are shameful—they’re your lifeline, not a white flag.

**Rule #3: Stay away from markets you don’t understand.**
Don’t get caught up in the hype of those wild, volatile markets. Wait until the daily chart clearly breaks out and trading volume spikes—then you’ll have much more certainty.

I have a friend in Shenzhen who used to blow up his account every month. After sticking to these rules, he turned 3,200 into 55,000 in four months. Now he tells everyone, “I used to think going all-in was seizing opportunities, but now I know you have to survive to get another shot.”

Crypto is full of overnight riches stories, but far more people quietly lose everything. The ones who last aren’t the biggest risk-takers—they’re the best risk managers. Remember this: slow and steady wins the race. Don’t fire all your bullets at once.
