Doing trading requires a degree of relaxation, not that you will make a fortune if you pinch a certain coin, nor that you will not make much money in the short and medium term. It depends on the timing of the respective buy and sell points and the base of the investment. It is important to understand that even in a bull market, there is no market that has been rising all the time and has not pulled back at all, and the price increase is determined by market supply and demand. It's like running alone, there will always be times when you are tired and need to stop and rest. It is precisely because of the continuous outflow and inflow of funds that short-term ups and downs have been formed, so that the long and short games have certain opportunities to operate in the short term. Sometimes, it is far better to retreat bravely and reduce positions at high prices than to regret why you didn't run earlier when the price falls and then runs or is trapped. The market will always be there, and there will be many opportunities. Selling for a while and a half is always a hundred times stronger than floating losses, you have to understand this sentence.
