When dealing with altcoins, you should not fixate on just one type of coin, as it can easily lead to rigid thinking. The biggest characteristic of altcoins is their high volatility. If you make a profit on a long position, many people will continue to enter long positions, but the market trend can change easily within an hour. Use the hourly chart to observe the trend, and the 15-minute chart to determine entry points and take profit levels. Avoid the 3-minute chart, as it really has little reference value. Keep your take profit and stop loss levels as small as possible. With so many altcoins available, high volatility indicates larger fluctuations in the range, and a strategy of small profits with high sales can also be very comfortable.
