CryptoFlash - Real-Time Crypto Portfolio Tracker

I built a crypto tracking app that's actually free (no ads, no BS).

Why I built it:

- Tired of crypto trackers with paywalls

- Wanted something fast and clean

- Practice React + Firebase + Stripe

Tech stack:

- React + Vite

- Firebase (Auth + Firestore)

- Shadcn UI

- CoinGecko API

- Deployed on Render.com

Looking for feedback! What features should I add next?
