Bitcoin's recent trend shows typical range-bound oscillation, with several key price levels visible on the technical chart.

Looking upward, the 90500 to 91000 range has formed a clear resistance. If the price can break through this level, attention should then be paid to higher resistance levels. On the downside, focus on the support zone between 88000 and 87800. If the price breaks below 87900, the risk will increase.

From a trading perspective, there are two strategies to consider:

1. Bullish scenario — go long in the low range from 88200 to 88500, with a stop-loss set below 87900. If the market moves upward as expected, the levels at 89200, 89800, and 90000 are reasonable profit-taking points, allowing for partial exits.

2. Bearish scenario — if the price shows resistance at the high levels between 92000 and 92500, consider shorting. The stop-loss should be placed above 92800 to prevent a breakout, while take-profit targets can be set at 90000, 89800, and 89000 in stages.

Overall, this is a relatively mature technical framework, but specific operations should be combined with real-time trends and individual risk tolerance.
