#数字资产市场动态 January 21 Bitcoin Morning Analysis

Looking at the four-hour K-line, the Bollinger Bands are clearly expanding and opening downward. Although the price temporarily broke below the lower band, it found short-term support at a key level, but the upper and middle bands continue to be pushed downward, indicating strong selling pressure. From the current position, a rebound from the lows is highly probable.

Early trading strategy: Start with a small position at the key support level to test long positions and capture profit from the rebound. Once the rebound momentum begins to weaken and clear signs of fatigue appear, decisively switch to short positions — this is a good opportunity for a reversal.

Specifically, $BTC can be lightly bought within the range of 88500-89200, aiming for a target of around 90200-91000 to see if it can stabilize. If this range is not broken and the price falls back, immediately switch to short positions.
