Recently, the four-hour chart of Bitcoin has been a bit tense. The price has been oscillating around 87,000, but the overall trend is clearly weak. It just broke below the middle line of the Bollinger Bands and is about to move toward the lower band. The MACD signals are not looking good—DIF and DEA negative divergence is widening, and the histogram is continuously growing, indicating that the bears haven't loosened their grip yet. Looking at the RSI, although the value is relatively low, it hasn't reached an obvious oversold level, so the chances of a rebound are not high.

In the short term, if the downward momentum continues, support around 85,700 should be approached with caution. The key is whether 87,000 can hold—this is an important watershed. Once broken, there could be more significant downside space. The current market is indeed weak, so everyone needs to keep a close eye on these levels and avoid being caught off guard.
