Recently, Bitcoin has been like a roller coaster, surging to 108,900 before sharply falling back. Many people are watching the K-line with accelerated heartbeats. In fact, there's no need to panic; 108,600 is like a 'ceiling,' and prices tend to pull back easily after hitting it. 107,400 is the 'watershed' of the medium-term trend; prices above it are strong, while breaking below it often leads to weakness. 106,200 is similar to a 'floor,' providing support during declines. Here, it is recommended to short directly at 107,400-107,500. #比特币
