Brothers, today I want to share some practical experience in trading contracts:
First, when you make a profit, you need to lock in the gains. For example, if you buy a coin and it rises more than 10%, you should be cautious. If it later falls back to your purchase price, sell immediately without hesitation. If you make a 20% profit, then set a rule that you won't sell unless the profit is at least 10%. Unless you're sure this is a temporary high point, don’t sell easily. The same logic applies: if you gain 30%, you should at least lock in 15% profit before selling. This way, even if you can't judge the high point technically, your profits can grow on their own.
Second, if you lose money, you must cut your losses decisively. If you buy a coin and it drops 15% (you can set this number yourself, but 15% is a good reference), you should quickly sell to cut losses. This is to prevent deeper losses and avoid getting trapped further. If it later rises again, that’s okay; it indicates your entry point was wrong. A mistake in trading comes with a price—losses. Remember, every trade must have a stop-loss set; this is an essential rule in crypto trading.
Third, if the coin you sold drops, buy it back at the original price. If you sell a coin and it falls, but you still believe in it, buy back the same amount of coins. This way, your coin quantity remains the same, but you have more funds on hand. If you didn't buy back after a small dip and later it rises back to your selling price, you must buy back unconditionally.
Although this may cost some extra fees, it can avoid many missed opportunities. This principle can be combined with the stop-loss rule: buy back when it returns to the original price, stop-loss when it drops. If you do this multiple times and find the coin’s price is always unstable, then you need to choose a new entry point.
In short, short-term trading in crypto must follow principles. Quick in and out doesn’t mean reckless; chasing hot spots doesn’t mean rushing blindly; taking profits when the time is right isn’t cowardly; holding cash and observing isn’t quitting the crypto circle. Don’t be too obsessed with the lowest and highest prices for buy and sell points.
Crypto trading is not only a contest of skills and luck but also a test of mindset and wisdom. Only those who master these iron rules and strictly follow them can stand undefeated in the crypto world!
