$BTC Several technical rebounds during the day were fleeting, encountering stronger selling pressure upon hitting key resistance levels, with prices continuously hitting recent lows, trapped in a cycle of "rebound - decline - new low." The intraday market showed limited fluctuations within a range; after a series of consecutive candles broke the middle track on the four-hour chart, a small bearish pullback occurred. Due to the lack of volume, it is highly likely that it will correct by exchanging time for space. Overall, before there is a clear bottom-building signal, we continue to be bearish overnight.
