Bitcoin completed a full cycle of "bottoming out - oscillation - reversal - surge and pullback" yesterday: after a low of $78,750 the day before, it experienced a slight bottoming oscillation, and yesterday at midday, a second test of $78,877 confirmed support, then rebounded to $79,900; after a brief pullback to $79,190 in the evening, it strongly rallied along with the US stock market, reaching a high of $81,988 in the early morning, approaching the $82,000 round number before facing resistance and pulling back, now entering a small consolidation range. From a technical perspective, the 4-hour chart formed a "double bottom" (78750/78877) followed by a volume-increasing bullish candle, directly repairing the previous decline platform, which is a typical "V-shaped reversal" pattern; however, after quickly retreating from the high of 81,988 in the early morning, the daily chart shows an upper shadow, indicating that selling pressure above 82,000 remains clear. The current price is oscillating between 81,200 and 81,500, with short-term moving averages turning upward but still in a choppy state in the medium to long term, the MACD fast and slow lines have formed a golden cross below the zero line with weakening momentum, and the RSI has fallen back to around 55. Overall, it is characterized as a transition phase between "the downtrend being broken but buying momentum weakening."
