Trading contracts is not difficult; what's hard is how to keep your profits after making money. Many people in the circle start by asking how to double their investments. I want to say, buddy, first learn to avoid losses before talking about making profits.

First point—protect your profits. If you buy coins like ZEC or UNI and they rise more than 10%? Be alert. If they later fall back to your purchase price, get out quickly. Don't think they can go even higher; sometimes taking profits promptly is more important than waiting for a big surge.

If you've earned 20%, set a rule for yourself: take at least 10% profit before selling. Unless you're very sure this is the peak of the stage, don't be greedy. Made 30%? Then ensure at least 15% profit. Operating like this over the long term, profits will naturally accumulate, and you can make money without relying on perfectly selling at the top.

Second point—cut losses when you lose. If you buy ALLO or other coins and lose 15% (you can adjust this ratio yourself; 15% is just a reference), cut your losses immediately and exit. Many people are reluctant to admit defeat, ending up more and more trapped. Every trade must have a stop-loss set; this is a rule, no exceptions. If it later rises? That means your entry was wrong this time. Mistakes come with a price, and that price is loss. Accept it, don’t argue.

Third point—if you sell and the price drops, buy back at the original price. If you sold coins and they now fall, but you still believe in them? Then buy back the same amount. This way, the number of coins stays the same, but your funds become active again. Or vice versa, if after selling the price didn’t drop much and later rose back to your sell price? Then buy back unconditionally. Although you pay a few more transaction fees, it helps avoid missing out on gains, which is quite cost-effective.

These three rules can be used together. When the price reaches the original level, buy back; if it continues to fall, cut losses. After a few operations, if you find a coin always fluctuates unstably at a certain price level? Then change the point and start over.

To put it simply, short-term trading is about principles. Quick in and out doesn’t mean reckless; chasing hot spots doesn’t mean rushing blindly; taking profits when the time is right doesn’t mean being timid. Walking blindly alone is less effective than following the team. The direction is clear; the key is whether you can keep up.
