**Option 2: Slightly More Detailed**

**Option 3: Focused on Practicality**

* **Description:** 關於比特幣價格的信息，包括實時價格、圖表、市場分析工具及相關新聞。 (Information about Bitcoin prices, including real-time prices, charts, market analysis tools, and related news.)

* **Explanation:** This option lists concrete elements, which would be a good idea for if you’re planning to include prices, charts, and more, rather than if you only intend to have price text.

**Key Considerations When Choosing:**

* **Content Plan:** What kind of content will be tagged with “比特幣價格查詢”? (News, charts, tutorials, analysis – all should be considered)
