Policy Update: 1. Take back some long orders, the position is still not as big as the previous paragraph (timid), part of it is to continue the trend, and part of it is to bet on making up for the rise; 2. Open a position in some of the short orders of the coins that went first some time ago and currently seem to have weakened momentum, thanks to @KristinAbr8059 for providing ideas for your kindness.
