BTC hourly volume suddenly surged, this signal isn't too good. The key is whether the subsequent hourly K-line can firmly hold above 91500. If it breaks below, I have a feeling the second half of the night will require staying alert—this is typical of a strong start with a weak finish, with bulls' efforts yielding no results. Why? Because the main force has deposited large amounts of chips here to suppress prices, clearly unwilling to let the coin price rise so smoothly. Once volume contracts and pulls back, there's likely another wave of selling pressure coming to confuse retail traders.

In any case, let's use 91500 as the dividing line—whether the closing K-line can hold above it will determine the rhythm for the next few hours. Of course, this is just a reference opinion, not necessarily 100% accurate. I'm going to sleep now; continuing to monitor the charts has no point.
