Selling in a bull market is a common occurrence, and you must not let the fact that you sold a coin at a loss affect your mindset.

Those who sell at a loss often have a psychological error, which is that if the current price is higher than their selling price, even if the market clearly indicates that it will continue to rise, it is hard to make up their mind to re-enter. They feel that the space of this part of the increase is a loss, and they form a mental anchor based on their cost price, leading to regret as they watch the price continue to rise despite their optimism.

This is a perspective error that results in profits being determined by direction rather than starting point; this starting point is what we call cost. Sometimes, it is necessary to sacrifice some early profits to gain greater trend certainty.

By overcoming this anchoring mentality, your trading will align more closely with price trends, making you more agile, as you grasp the essence of profit sources.

This is difficult to achieve, so the strategy I currently use is divided into long positions and ultra-short positions. For long positions, I buy coins that I believe in for the long term and hold them until they reach my target price. For short positions, I buy currently active coins with a clear upward trend, feel the rhythm of their price fluctuations, and trade in waves. If a true wave flies away, I look for the next one, which also helps me improve my ultra-short trading skills.
