Bitcoin has recently been fluctuating within a range, but the signs of long positions building up on the 4-hour Candlestick Chart have become increasingly evident. Although the previous attempts to surge have been suppressed, each pullback's low point is rising, indicating that the support below is very solid, and the willingness of market participants to go long is accumulating.

From the overall rhythm, long positions have the upper hand. The current stage of fluctuation is essentially a buildup, belonging to the consolidation phase of the upward process. This kind of trend often indicates that there will be another upward movement relying on the support level.

From an operational perspective, the current strategy should primarily focus on going long on pullbacks. Specifically, Bitcoin can be considered for positioning within the range of 86800-87300, with the target pointing towards the area of 88000-88500. Once support is validated again, the probability of an upward movement will be relatively high.
