BTC price movement observation: If Bitcoin faces resistance and falls back from the 88K to 88.2K range, this failed rebound signal is worth following for shorting opportunities. However, be aware that once the price holds above 88.5K, the previous short positions strategy will need to be adjusted—this price range is the boundary between key support and resistance. In the short term, closely monitor the performance of these three key price levels: the pressure at 88.2K, the defense line at 88.5K, as a breakout or pullback will provide clear trading direction guidance.
