Bitcoin continued its decline yesterday, forming a unilateral oscillating downward pattern. After a brief test of 71,500 in the morning, it was pressured downward all the way, showing a "small step" decline during the day, with each wave of decline not large, but rebounds extremely weak, with the bulls having no resistance. In the early morning, it dipped to 67,041 before slightly rebounding to 68,100, but the rebound was quickly cut off, and the price fell back to 66,366; this morning, stimulated by news, the price suddenly broke through 66,160, hitting a new low in this round of decline, currently rebounding slightly to around 66,500 for consolidation, and is now in a 4-hour accelerated downtrend channel, with the price continuously breaking key supports like 67,000 and 66,160, with lows gradually moving lower. The rebound candlestick bodies are very small and shrinking in volume, Bollinger Bands are expanding downward, MACD shows a dead cross with increasing green bars, RSI entered the extreme oversold zone below 20 but did not form a bullish divergence, and the volume-price relationship shows a typical bearish dominance pattern. During the daytime rebound, focus on the 67,500-67,800 zone; if it faces resistance and stalls, it can continue to go short from higher levels, with a stop at 68,300, and targets at 66,200 (breakout point), then 65,000, and 63,500. If it directly breaks below 66,200 with volume, a light short position can be taken. Until a volume-driven bullish candle recovers above 69,000, maintain the main strategy of high-level shorting on rebounds, avoiding guessing bottoms or bottom-fishing.
