Sea of Coins Surfing: 12.15 Bitcoin (BTC) Market Analysis Reference:
Bitcoin maintained a narrow range of oscillation over the weekend, with bulls and bears tugging back and forth around the 90,000 level. Last night, the market suddenly turned, with bears gaining momentum, causing the price to fall sharply with consecutive declines, touching near the 87,500 level before starting to stabilize and rebound. As of now, Bitcoin has rebounded to around 89,600 and is oscillating, returning to the lower end of the previous trading range in the short term.
From the daily chart perspective, after several days of consecutive bearish candles, the current price has fallen below the short-term moving average. The Bollinger Bands are gradually narrowing, with the upper band falling back to 93,700 and the lower band rising to 87,300. The current price is below the middle band of the Bollinger Bands and has not yet broken through effectively. The midline (90,500) has become the short-term dividing line between bulls and bears. If the price cannot stay above this level, the subsequent trend is likely to continue oscillating and correcting, further testing the support around 87,300.
From the short-term chart perspective, the 4-hour candles initially formed a "two consecutive bullish candles" pattern and gradually approached the middle Bollinger Band but failed to break through due to resistance, then fell back. The KDJ indicator's three lines have completed a bullish crossover from a low position, with the J line quickly rebounding from oversold areas. The DIF and DEA are showing signs of forming a golden cross below the zero line. However, it should be noted that the current rebound has clear constraints: on one hand, the MACD histogram (red bars) continues to narrow, indicating weakening bullish momentum and insufficient momentum for sustained volume expansion; on the other hand, the price remains below the middle Bollinger Band, and the DIF and DEA have not yet officially moved above the zero line to confirm a valid golden cross, nor have they broken through the core boundary of the "weak trend" pattern. Overall, this 4-hour rebound is more of a "technical correction after pullback" rather than a trend reversal. Future focus should be on breaking above the middle Bollinger Band (89,800); if volume increases and MACD confirms a golden cross, the rebound may continue. If price remains constrained below the middle band, it is likely to fall again.
