It is a difficult question to follow the trend or the fluctuation. For xai, many times, when there is a short-term top, I choose to hold it instead of clearing the position. At most, I will reduce the position. The same is true for bb. From 30% profit to returning to the starting point, if you choose to give up long-term holding, the profit will be greater now. The risk of long-term holding is that if it is not the bottom range at present, there is also the risk of big losses or even liquidation. But at present, I am still focusing on the trend, so I ignore the fluctuations in the middle.
