There is an old saying in contract trading—those who don't cut losses will eventually see their accounts go to zero.

I've seen too many examples. Accounts grow from tens of thousands to hundreds of thousands, seemingly on the verge of success, only to lose everything in one hesitation. These people are often not wrong about the market direction, but they simply didn't leave themselves an escape route from the start.

In fact, the market doesn't suddenly turn bad; the key is that at that moment, you chose to "hold on a little longer."

I've also suffered losses myself. When entering against the trend, I wanted to wait for a pullback; when it broke out, I wanted to take more profit. Often, it's not that the market doesn't give opportunities, but that you didn't execute a stop-loss, allowing losses to grow step by step.

Later, I realized a truth—making money in contracts isn't about winning more often, but about how much you can lose at most each time. This is the survival bottom line.

Now, my trading logic is very simple. Before placing an order, ask yourself what the worst-case scenario you can accept is, set the stop-loss position in advance, and when the price hits, exit automatically. No change, no delay, no entanglement.

The higher the leverage, the narrower the tolerance for errors. The size of the drawdown you can handle should match your position size. It's not about turning things around in one shot, but about ensuring each failure is within a controllable range.

Even when there's unrealized profit, don't relax. Unrealized gains are not a reason to be impulsive, but a reminder to lock in profits. The market can fluctuate, but the profits already in hand shouldn't be completely given back.

There's also a detail many people overlook—emotions also need stop-loss. Stop trading after a series of losses; leave the market if your state is out of control. Opportunities in Bitcoin and other cryptocurrencies are indeed plentiful, but so are the traps. Very few people can truly make money; the key is to stick to the rules.
