Let me talk about one reason for the loss in the bull market. Although a certain investment target has made a profit, you will continue to switch positions to other currencies that are hot or relatively undervalued. You will always be fully invested and excited. However, when the bull turns to bear, there will be a sudden plunge. As long as you don’t stop profit before this point, you will most likely leave the market at a loss in this bull market. Therefore, the best state is to sell while the market is rising. Don’t sell at the highest point. Only when the liquidity of the bull market is very good, you can leave safely!
