Crypto Price Ticker
Live coin prices that refresh themselves every few seconds.
A little price board for Bitcoin, Ethereum and friends that updates on its own. You'll learn polling — re-fetching on a timer — plus formatting money and coloring gains green and losses red.
What's inside
- Live prices with 24h change, up or down
- Auto-refresh on a timer (polling)
- Green / red change indicators
- Keeps the last good values if a refresh is rate-limited
- Free API, no key required
