At present, there are no new long orders. Almost all those who should have entered the previous bottom have entered. It is not too late to speculate now. The risk is high. This round of increase has exceeded most people's expectations. At present, the more the pie rises, the higher the cost-effectiveness of shorting. The short-term upward space is definitely not as large as the downward space. This industry is a game of compound interest, not a big profit at once. Don't cultivate your gambler mentality. If you have a lot of profits, you should reduce your positions.
