There are multiple ways to generate passive income on eBay, for example:
Selling digital items
Selling Print-On-demand products
Dropshipping
Affiliate marketing (available only in limited countries)
I have used all of these methods and made money from eBay. When you sell physical products you will have to do substantial amount of work but when you are selling aforementioned items, you do not have to work much, for example, you do not have to pack the products and ship to the buyer address.
