BTC has three incense sticks on top, short-term surge followed by a quick pullback, 4-hour candlestick closing, divergence between volume and price, the final trap for the bulls, bullish momentum shows obvious signs of exhaustion, the bulls are already at the end of their strength, indicating a testing of this level. If it does not break 7.9, then currently it is the last chance for the bulls to escape the bottom. The US dollar index is currently unable to move downward, it may rebound at any time, and risk assets like cryptocurrencies will fall. Focus on two key levels: the resistance at 7.9 and the support at 7.6, watch whether it breaks through or stabilizes before taking action. Short at 78,800-79,500, with a defense at the 80k mark.
