  Sure, here's how you can use HTML option groups to display cryptocurrency data. First, create a select element with the 'multiple' attribute to allow multiple selections. Then, use the 'optgroup' element to group the options. Each 'optgroup' should have a 'label' attribute to specify the name of the cryptocurrency. Finally, add the 'option' elements within each 'optgroup' to display the specific data for that cryptocurrency. Make sure to include the necessary JavaScript code to retrieve and update the data dynamically.
