Bitcoin's daily K-line recently shows a pattern of consecutive bearish candles with continuous release of selling pressure, and the price center continues to move lower. Currently seeking support near the middle band of the daily Bollinger Bands. From a chart perspective, the price action is again trapped in a daily K-level box oscillation. The 90000 level is very critical - whether the bulls can hold this line above will determine the subsequent market direction.

If it can't hold this evening and breaks through to form a solid candle body, risk could further expand, and the 85000 support level below is likely to be tested.

Reference Suggestions:

- Ethereum follows the downside, pay attention to the 3000 USD price level
