  Sure, I can help you with that! To track cryptocurrency price updates using the js addeventlistener function, you first need to select a reliable cryptocurrency API that provides real-time price data. Once you have chosen an API, you can use the addeventlistener function to listen for changes in the price data. Whenever the price updates, the addeventlistener function will trigger a callback function that you can use to update the price on your website. Here's a basic example of how you can implement this: ```javascript const priceElement = document.getElementById('price'); function updatePrice(price) { priceElement.innerText = price; } const apiEndpoint = 'https://api.example.com/price'; function fetchPrice() { fetch(apiEndpoint) .then(response => response.json()) .then(data => updatePrice(data.price)); } fetchPrice(); setInterval(fetchPrice, 5000); // Update price every 5 seconds ```
