#BTC资金流动性 $BTC is fluctuating back and forth in a range with weak liquidity, with obvious upward pressure. Currently, focus on observing two key positions:

**Support Below**: 85000 is a watershed. As long as it holds here, you can consider entering with a light position on dips, waiting for a rebound opportunity. Once it breaks down, the subsequent downward space will look at 83000-80000, so be mentally prepared.

**Resistance Above**: To rebound strongly, it is necessary to break through 88500 with significant volume. This is not a minor rebound; it requires accompanying trading volume. Only if the rebound holds above 88500 can we look towards the target of 90000.

The overall rhythm at present is a weak oscillation within a range, with short-term fluctuations repeatedly competing in the area of 85500-88500. Liquidity is temporarily insufficient, and a clearer signal is needed for the general direction.
