#比特币流动性 On the afternoon of December 24th, $BTC and $ETH continued to fluctuate downward. The early session's single-sided decline was confirmed, with Bitcoin and Ethereum each dropping by 809 points and over 50 points respectively.

From the four-hour chart, the situation is quite clear—Bollinger Bands' three lines are moving downward in unison, and the distance between the upper and lower bands is widening, providing structural support for continued weakening. Bitcoin is currently deep in a downtrend channel, with candlesticks consecutively closing lower, and the medium-term trend has been established. The bearish momentum remains sufficient; from the MACD, the two lines are approaching the negative zone, the selling volume bars show increasing signals, and there are no signs of weakening in the downward momentum.

On the hourly level, the fast and slow lines form a death cross below the support zone, and the three lines of KDJ are also in a weak state. It is expected to continue seeking a bottom in the short term.

In the afternoon, the trading strategy is to continue shorting. Bitcoin can be shorted around 87,500-88,000, with a short-term target of 86,500. If it breaks below this level, look towards 85,500. Ethereum can be entered in the 2,940-2,970 range, with a short-term target of 2,900, and after breaking through, focus on around 2,830.
