First, when making money, you must protect your profits. For example, if you buy a coin and it rises by more than 10%, you need to be careful. If it drops back to your purchase price, sell it immediately without hesitation. If you make a 20% profit, you need to set a rule for yourself that you cannot sell unless you have at least a 10% profit, unless you are certain this is a temporary high point; otherwise, don't sell easily. The same goes for if you make a 30% profit; you must at least protect 15% of your profit before selling. This way, even if you don't have the technical skills to judge high points, you can still let your profits grow on their own $BTC

Second, if you are losing money, you must decisively cut your losses. If you buy a coin and it loses 15% (you can set this number yourself, but 15% is a suitable reference), you need to quickly sell to cut your losses. This is to prevent yourself from falling deeper into losses. If it rises afterward, that's fine; it just means you chose the wrong entry point this time, which is a mistaken trade, and mistakes come with a price, which is the loss. Remember, every time you open a position, you must set a stop-loss; this is an essential condition for trading coins #Crypto
