  You can definitely use JavaScript to display live cryptocurrency prices on your website. Here's a simple approach you can take: 1. Choose a cryptocurrency data provider: There are several APIs available that provide real-time cryptocurrency data. Some popular options include CoinGecko, CoinMarketCap, and Binance API. 2. Sign up for an API key: Once you've chosen a data provider, sign up for an API key. This key will allow you to access the provider's data. 3. Make API requests using JavaScript: Use JavaScript to make API requests to the chosen provider's API. You can use the Fetch API or libraries like Axios to make HTTP requests. 4. Parse the response: Once you receive the response from the API, parse the data to extract the relevant information, such as the current price of the cryptocurrency. 5. Display the data on your website: Finally, use JavaScript to display the parsed data on your website. You can update the prices periodically using timers or websockets to keep the information up to date. Here's a simple code example to get you started: ```javascript const apiUrl = 'https://api.coingecko.com/api/v3/simple/price?ids=bitcoin&vs_currencies=usd'; fetch(apiUrl) .then(response => response.json()) .then(data => { const bitcoinPrice = data.bitcoin.usd; document.getElementById('bitcoin-price').innerText = bitcoinPrice; }); ``` Remember to replace `bitcoin-price` with the ID of the HTML element where you want to display the price. I hope this helps! Let me know if you have any other questions.
