Bitcoin continued to fluctuate around 91,300 this morning, dropping to 90,519 in the early hours before rebounding. From a technical perspective, the current trend is a correction after a high-level pullback.

The market shows a clear battle between bulls and bears. The daily chart still favors the bears, but the lower band of the 4-hour Bollinger Bands around 90,000 has formed a relatively strong support. This level is very critical.

The operational idea is as follows: if there is a rebound to the 92,000-93,000 range, consider short positions. The first target is 90,800, and if the support breaks further, then 90,000. Currently, close attention should be paid to whether the Bollinger Bands can hold, as this will determine the future trend. Overall, the bulls and bears are still in a tug-of-war, so patience is needed until clearer signals emerge.
