Currently, Bitcoin is fluctuating around 81,000. From the 4-hour Bollinger Bands perspective, the middle band support is at 80,800, and the upper band resistance is at 82,500. The overall trend remains bullish.

The Bollinger Bands are opening upward, with the middle band continuously rising, indicating that the medium-term upward trend has not been broken. As long as it does not effectively fall below 80,800, the bullish pattern will not change.

From the recent high of 82,800, there has been a pullback. The pressure near the upper band is obvious, and there is no sign of a volume breakout. Therefore, the probability of a straight large upward move is low; a more likely scenario is a sideways to slightly bullish consolidation.

Suggestions:

1. Do not chase highs: The pressure in the 82,500-83,000 range is very strong. Chasing in could easily lead to a quick rise and fall, resulting in being caught.

2. Focus on buying the dip: Look for stabilization around 80,800-81,000, then consider light positions to try for long entries. Place stop-loss below 80,500, with targets at 82,000-82,500.

3. Control position size: At this level, neither up nor down, any heavy position operation is prone to being stopped out by swings. It is recommended to keep positions within 10%.
