BTC on the weekly chart as of December 29th needs to be cautious of the risk of opening high and closing low. The bottom MACD at the 3-day level is still continuously releasing green bars, indicating there is still room for recovery below. Looking downward, the 2-day and 1-day effective timeframes are both in a bottoming phase, and the 8-hour level is also in the bottom area.

In the short term, several risk points need attention: there is a possibility of a rebound at the 3 to 6-hour levels, especially if the 2-hour breaks above, which could trigger an implicit signal on the 15-minute level.

The key resistance levels above are in the ranges of 88480, 89288, and 90320. The support levels below are sequentially at 87826, 87324, 86807, and 86241.

From market sentiment, BTC's long-short ratio has reached 2.20, and the fear index is at 30, indicating a relatively calm overall atmosphere. Remember a principle: don't act without a clear pattern; never open a position without a stop-loss. These data are for reference only and do not constitute any investment advice.
