    The on-change event in jQuery can be used to automatically update cryptocurrency prices on a website. When the user changes the value of an input element that represents a cryptocurrency price, the on-change event is triggered. You can then use this event to fetch the latest prices from a cryptocurrency exchange API and update the displayed prices on the webpage. This allows for real-time updates of cryptocurrency prices without the need for manual refreshing. To implement this, you need to attach the on-change event listener to the input element and define a function that will be executed when the value changes. Within this function, you can make an API call to fetch the latest prices and update the displayed prices on the webpage. It's important to handle any errors that may occur during the API call and update process to ensure a smooth user experience.
