  Sure, you can use the add event listener method in JavaScript to track cryptocurrency price changes in real-time. Here's how you can do it: 1. First, you need to find a reliable API that provides real-time cryptocurrency price data. There are several APIs available, such as CoinGecko API or CoinMarketCap API. 2. Once you have the API, you can use JavaScript to make an HTTP request to the API and fetch the price data. 3. After fetching the data, you can use the add event listener method to listen for changes in the price data. For example, you can add an event listener to the 'price' property of the data object. 4. Whenever the price changes, the event listener will be triggered, and you can perform any actions you want, such as updating the price on your website or sending a notification. Remember to handle any errors that may occur during the process and make sure to update the data at regular intervals to keep it real-time.
