Trading contracts, the ultimate goal is just one—make money for a lifetime, not spend your whole life just earning. Today, I want to share some practical experiences, hoping to help everyone become more steady on the road in the crypto world.

**Tip 1: Lock in profits once you make money**

Buy a coin, and if it rises more than 10%, you must be extra cautious. Once it returns to your cost basis, don’t hesitate—exit immediately.

If you earn 20%, set a rule for yourself—only sell if at least 10% of that profit is retained, unless you can be 100% sure this is the local high, then ignore it. The same applies for 30% gains—protect at least 15% of the profit before selling.

The beauty of this approach is that even if you can't pinpoint the market top, profits can accumulate gradually. Earning a little less is not shameful; surviving is the real key.

**Tip 2: Don’t wait even a second if you’re losing money**

Conversely, if your position drops 15% (you can adjust this ratio, but 15% is a good reference), then run.

Cut your losses promptly—this is the first step to self-rescue. Don’t let yourself sink deeper. If the coin recovers later? No problem, that just means your entry timing was off. It’s a losing trade, and losses are the cost—accept it.

A necessary habit: set a stop-loss at the time of opening each position. This isn’t optional; it’s essential for short-term trading.

**Tip 3: After selling, if the coin drops, buy back at the original price**

You sell a coin, and later it falls, but you still believe in its long-term prospects. So, buy back the same amount. This way, your coin holdings stay the same, but you have extra cash to use for the next wave.

Conversely, if the price doesn’t rise much after selling and you don’t buy back, but it later returns to your sell price, you must grit your teeth and buy again. Although it costs more in fees, it helps avoid missing out on the rebound.

This rule can be combined with stop-loss: buy back if it recovers to the original price, and set a stop-loss if it falls again. Repeat this process multiple times; if you find the price keeps oscillating unstably, it’s time to switch to another coin and start fresh.

**Final words**

Short-term trading is about principles. Quick in and out doesn’t mean reckless chopping; chasing hot spots doesn’t mean blindly following the crowd; taking profits when the time is right doesn’t mean lacking courage; sitting on the sidelines watching the market isn’t giving up on crypto. Don’t obsess over the lowest or highest prices—fixating on these points is a big taboo. The market will always give opportunities to those who are prepared, but only if you live long enough.
