Free books and comics desktop app

Hello, I'm thinking in make a desktop app to read books and comics from the web.

My plan is to download comics and books and upload them to a server a let the users select from the app what book or comics he/she want to read.

The application will be free, so I'm thinking in put ads on the application, and using a monero minning at 10% of the machine power when the user is reading the book.

What will be the best way to monetize an app like this?

Something like Nanits?

yes, something like that but for windows
