💹 Crypto Analyzer

Crypto Analyzer is a web-based application built with Node.js, Express.js, and EJS that allows users to search and analyze real-time cryptocurrency market data.

⚙️ How It Works

1. User Interface:

   • The homepage shows a search bar that lets the user type in a cryptocurrency symbol (e.g., BTC-USD, ETH-USD).
   • Matching suggestions appear below the input box.

2. Form Submission:

   • Once a crypto symbol is selected, the app fetches:
     • Current price data from Blockchain.com
     • Historical price data from CoinGecko (mapped internally via symbol-ID mapping)

3. Chart Rendering:

   • Chart.js is used to display a line chart of recent prices for that crypto asset.
