Bitcoin price tracker

Current price of bitcoin

As someone new to the world of Bitcoin and decentralized technology, I wanted to build something simple yet useful for people who want to stay financially aware without relying on centralized platforms or apps. The theme of the MIT Bitcoin Hackathon , Freedom Tech , inspired me to create a tool that supports self-reliance and open access to real-time information.

This project is my first step into Bitcoin-related development, and I wanted it to be accessible for beginners like myself while still aligning with the principles of financial freedom and transparency.

I built a simple web-based app using HTML, CSS, and JavaScript. It fetches the current Bitcoin price using the CoinGecko API and displays it on the page. Users can input a target price, and the app will automatically alert them if Bitcoin reaches or exceeds that value.

Features:

✅ Real-time BTC price updates every 10 seconds

✅ Price alert input with popup notifications

✅ Clean and responsive UI with custom styling

Since I’m new to Bitcoin and hackathons, I wasn’t sure what kind of project would be considered valid — I focused on keeping things simple and functional.

Learning how to work with APIs and handle potential errors (like failed fetches).

Designing a UI that looks decent while still being easy to code.

What I Learned How to use public APIs (CoinGecko) to fetch real-time data
