Bitcoin, after hitting the 88131 level in the evening session, has since been oscillating within a narrow range. Neither the short-term high nor the low has been effectively broken. The current market correction process is not yet complete, and the trend exploration continues. From a daily chart perspective, the candlesticks are operating near the lower Bollinger Band, with the space gradually opening up. The lower band remains under downward pressure, testing for a bottom, indicating that the bearish trend is gradually emerging. On the four-hour chart, the three Bollinger Bands are extending downward in unison, clearly showing bearish sentiment. During the evening rebound to near the middle Bollinger Band, the price faced strong resistance and quickly fell back, with the middle band forming a solid resistance level. The short-term rebound momentum has already exhausted. The subsequent strategy is clear: rely on the middle band as resistance and continue to adopt a bearish outlook on rallies.
