Bitcoin four-hour cycle chart shows a clear trend; the rally to the key resistance zone around 673 has pulled back for correction, with limited retracement strength, not breaking below the middle band of the Bollinger Bands, indicating strong short-term support.

In the small intraday cycle, short-term indicators show weak adjustment; short-term bears exert slight pressure, but this is a technical pullback during an upward trend, not damaging the four-hour bullish structure, so the short-term upward trend remains intact. The Bollinger Bands indicator is opening upward, with all three bands moving higher in sync, and the long-term bullish environment remains unchanged.

Based on multi-cycle signals, the main pattern dominated by the bulls remains unchanged; it is recommended to follow the trend.
