Contract experience sharing first, when you make money, you must protect your profits. For example, if you buy a coin and it rises by more than 10%, you need to be cautious. If it later drops back to your purchase price, sell it immediately without hesitation. If you make 20%, then you need to set a rule for yourself that this time the profit cannot be less than 10% before selling, unless you are sure this is a temporary peak; otherwise, don't sell easily. The same logic applies if you make 30%, at least you must protect 15% of the profit before selling. This way, even if you lack the technical judgment of the peak, you can still let your profits roll up. $BTC

Second, if you lose money, you must decisively cut losses. If you buy a coin and it loses 15% (you can set this number yourself, but 15% is a suitable reference), then you must quickly sell to minimize loss. This is to stop the loss in a timely manner and not let yourself get deeper into trouble. If it rises later, that's okay; it means you chose the wrong entry point this time, and that's a bad trade. Mistakes come with a price, which is the loss. Remember, every time you open a position, you must set a stop-loss. This is a necessary condition for trading coins. #CryptoKnowledge #EvenBeginnersCanUnderstand

Third, if the coin you sold drops, buy it back at the original price. If you sell a coin and it drops, but you are still optimistic about it, then buy back the same amount of coins. This way, your quantity of coins remains the same, but you have more funds on hand. If it doesn’t drop much after selling and you didn't buy back, and then it rises back to your selling price, you must unconditionally buy it back.

Although this will waste some handling fees, it can avoid many risks of missing out. This principle can be combined with the stop-loss principle, which is to buy back when it returns to the original price, and stop-loss if it drops again. If you do this multiple times and find that the price of this coin is always unstable, then you need to choose a new entry point.

In summary, short-term trading in coins must follow principles. Quick in and out does not mean blindly messing around, chasing hotspots does not mean randomly colliding, taking profits does not mean being timid, and staying in cash to observe does not mean exiting the crypto world. Don't get too hung up on the lowest and highest prices for buying and selling.
