加密货币与贵金属监控

**Quick judgment** A focused, CLI-oriented market monitor that combines BTC/ETH and gold/silver prices, plus FX and basic analytics, with no API key required. Well-suited as a lightweight dashboard for casual monitoring and simple alerts, but not a full trading or portfolio management tool. **Main strengths** - Consolidates crypto and precious metals prices with USD/CNY support. - Offers comparisons, 24h rankings, and simple price alerts. - Uses public, no-key APIs, minimizing setup friction. **Key risks & limitations** - Data latency of ~15–60 seconds; not suitable for high-frequency or execution-critical trading decisions. - Precious metal APIs may hit daily request limits, potentially degrading reliability. - Alert delivery depends on the skill running continuously; missed or delayed alerts are possible. - Only a small set of assets is supported out of the box; other coins require extension. **Recommended scenarios** - Users who want a simple, always-on quote/monitor panel for BTC, ETH, gold, and silver in a terminal-like environment. - People comparing crypto vs gold/silver as "store of value" or hedge assets over short horizons. - Learners or analysts needing quick reference prices without managing API credentials or complex UIs.
