Build me a full stack Bitcoin sentiment dashboard that watches crypto news, figures out whether the market mood looks positive, negative, or mixed, and turns that into a simple BUY, SELL, or HOLD signal with a confidence score.

I want a backend that pulls in headlines from a few RSS feeds on a schedule, checks BTC price data, stores everything in MongoDB, and exposes simple API endpoints for the latest signal, recent sentiment, price history, and a manual refresh button. It should also have a streaming AI explanation endpoint that gives a plain English summary of why the current signal is what it is.

On the frontend, make a clean dashboard that shows the current signal, the price chart, recent headlines, and the AI explanation in a nice readable way. If you need current docs for the AI or charting pieces, look them up online. Also make it easy to run locally with clear environment variables and include basic end to end tests.
