Bitcoin daily Bollinger Bands remain in a downward trend overall, with the upper band continuously declining, and the price operating below the middle band, indicating that the medium- to long-term downtrend has been established, and the upward rebound space has been significantly compressed. Currently, focus on the key strong resistance level around 64,300 for Bitcoin. If the price cannot break through with volume, any rally should be viewed as a correction within the downtrend. The candlestick repeatedly shows long upper shadows at high levels, indicating extremely heavy selling pressure above, so the trading strategy remains to mainly buy the dip on rebounds.
