$BTC BTC tonight entered the upper vacuum zone with increased volume, and after holding above 768-770, a pullback formed, which is basically in line with expectations. Subsequently, it moved into the main capital concentration area, probing downward from the upper boundary. Currently, observing the main capital's dynamics suggests there is still further downward potential, so attention should be paid to whether 755 can hold. If it cannot, the price may further retrace to 750 and the dense zone below at 738-750! At present, the selling pressure from the main capital exceeds the buying pressure. The overall strategy tonight is relatively clear: a move down first, then up. The key level to watch above around 750 is whether 768 can stabilize. Once stabilized, the next target is to see if it can reach 775 or even new highs.
