Today, Bitcoin has formed a weak unilateral decline structure, starting to weaken after facing resistance around 81,900 in the morning, accelerating its decline during the European and U.S. trading sessions. After the negative CPI data was released, the bears further increased their volume, with the lowest point touching around 79,800 overnight, and currently, the price is consolidating near 80,400 at a low level, with a daily drop of over 2,000 points. Ethereum also weakened simultaneously, rising to 2,340 in the morning before facing resistance and falling back, with the lowest dropping to around 2,255 overnight. It is now fluctuating around 2,275, and overall, the market trend is dominated by bears, but this is not a sign of a trend reversal. The intra-day Bitcoin layout has a total space of about 1,900 points; Ethereum's long positions were mostly closed at a loss, and the current state is capital preservation. Long positions are still held within the day.

On the daily chart, the current bearish candle has a large body, completely engulfing the rebound space of the previous three days, but overall, it remains within the upward channel. The middle band of the daily Bollinger Bands at 79,000-79,500 is the key to this rally; as long as it is not broken, the trend cannot be considered bearish, only a deep correction. On the four-hour chart, the volume-driven decline overnight directly broke through the previous days' consolidation platform, with the price moving from above the upper Bollinger Band at 82,000 through the middle band, and only stopping and rebounding near the lower band at around 80,000. In the naked K-line pattern, three consecutive bearish candles have been formed, releasing strong bearish momentum, but the support at the 80,000 lower band and the previous low at 79,800 form a double support. After touching it overnight, a lower shadow was immediately formed, indicating that buying interest in this area is still resisting. On the one-hour chart, 80,400 is currently the core position for short-term trading. After rebounding to the 80,400-80,500 zone, the price moved sideways, which coincides with the previous four-hour support turned resistance. If it breaks below this level, it becomes a resistance level. If the rebound cannot stabilize above 81,000 in the short term, the weak structure will be difficult to reverse. The overnight strategy is still to look for long positions.

Initially, observe the support effectiveness around 79,800-80,000 for Bitcoin. If this holds, a small position can be taken to bet on a rebound, with the upside target at 81,000-81,500 resistance zone. If the rebound at 80,400 is weak and the second decline breaks below 79,800, then focus shifts to the core support band at 79,000-78,500. Ethereum's key support at 2,250 has been recovered; if it further rebounds and stabilizes above 2,280, there is still hope for a rebound to 2,330-2,350. If the decline continues and breaks below this level, attention should turn to 2,200.
