Build me a simple single page web app called BTC Predictor.

I want it to feel like a clean Bitcoin forecasting tool where someone can enter a few basic details and see a predicted price or trend result on the page. Make it look modern and easy to use, with a clear header, a simple form, and a results area that updates when the user runs it. If it makes sense, add a small chart or visual indicator so the prediction feels more useful.

Keep it all in one HTML file if possible, since this project looks very lightweight. Make the page responsive so it works on mobile too. If you need current info or libraries, look up the latest docs online.
