The center of $BTC 4H level has been formed. The high point last night started to go down the 30F divergence segment. Currently, the first segment is down 5F. There are at least two more 5F trends, one up and one down. The 4-hour moving average short position is well arranged. In the short term, we continue to maintain the idea of ​​rebounding and shorting. We can enter the market when it rebounds around 65300, and stop loss is above yesterday's high point. It is expected to continue to fluctuate downward in the future, and the medium-term target of 62500 remains unchanged.
