Recently, a brother asked me how to grow small funds into large ones, and his experience is quite worth sharing.

Starting from 3000U, he managed to reach 46,000U in just over three months. It’s not really about luck; it’s about sticking to one principle: first figure out how much you could lose in the worst case, then think about how much you can make.

Most retail investors end up not getting out because it’s not that the market is really bad, but because they didn’t plan their exit strategy and rushed in. It’s like driving without knowing where the brakes are—dangerous.

**How to Play with Contracts**

Short-term trading requires small stop-losses. I usually use about 5x leverage, set a target of 5-8% increase, and keep the stop-loss within 3%. For example, with ETH and a trading size of 8000U, if you lose 3%, you must exit; if you gain 6-8%, take profits immediately.

Sounds like not much profit? In two weeks, that’s over 3000U in gains. In a month, that’s a small goal achieved. Don’t be greedy; stable compound interest is more effective at building wealth than occasional big profits.

**Another Logic for Spot Mid-term Trading**

To gain 30-40% in spot trading, you need to stay calm. A 5% pullback is nothing to fear; it’s normal market breathing. The real stop-loss point should be set at the previous low or the 60-period MA on the 4-hour K-line. Once broken, exit.

Take profit in two steps: when it rises 30%, sell half to lock in gains; if it retraces 7-8%, close all remaining positions. This way, you won’t exit too early, nor will you be greedy at the end.

**Position Size Is the Last Line of Defense**

I’ve found that most people’s problems are not with trading techniques but with position management. With a small position, even an 8% retracement can keep you rational; but if you go all-in, a 2% loss can make you panic.

Trading heavily without setting a stop-loss is like driving on a highway without brakes—inevitably, something will go wrong.

**The Most Important Sentence**

Stop-loss is for survival; take-profit is your dividend. Before placing each order, think clearly about how you might lose and how to get out, then consider how much you can earn.

Market opportunities come in waves; there are always new ones. But if your principal is gone, no matter how many opportunities there are, they won’t matter to you.
