$PTB 4 hours K-line shows significant volume, but the cost hasn't turned negative, indicating that many people have been buying in all the way up. However, if it continues to rise, some may start to short. Shu has taken fans all the way up on this trade and has already made a lot of profit; a good portion of the base has been realized. Currently, I don't see any conditions for shorting, and I don't plan to enter a short position in the short term. I will continue to hold long positions. The next resistance level is 0.007. It will be better to short once it forms a head structure. Those who are stuck can also seek help from Shu to get out.
