What is Info Crypto?
Info Crypto is a modern React web application that gives users a real-time window into the cryptocurrency market. It pulls live data from public APIs to display prices, market statistics, historical charts, and the latest news — all without requiring an account or API key for basic usage. The app is built as a portfolio project demonstrating production-grade frontend engineering practices: smart caching, clean component architecture, responsive design with Tailwind CSS, and smooth dark/light mode support.Key features
