From the market perspective, the upper pressure for BTC is around $89,000, while support is in the range of $83,500 to $81,500. In the short term, the hourly chart clearly shows significant capital outflows, with a rapid withdrawal after a peak, resembling a false bullish trend. As for strategy, if BTC touches around $88,500, one could consider taking a small short position, setting a stop loss at $91,000, and targeting a $5,000 downside.

Additionally, the US stock market remains weak, and market sentiment is cautious, with no significant signs of capital entering. Therefore, BTC's resilience against declines feels somewhat unnatural. Is it strong or weak? Let the market speak for itself; a sharp drop may be lurking around the corner waiting for the right moment. Here’s a bold guess—there might be significant fluctuations within three days, so let’s wait and see!
