I've been looking for the answer to this question lately. How can I earn passive income from the internet? I have seen many of the answers given in my research on the internet. but many of them unfortunately didn't work for me.
The only thing that can give you money on internet is skills, and that skills you have to offer must be unique and classic to your client otherwise you wouldn't really make much or may not even sell anything.
You have to make your skill sale more than others else, you would just be just be cycling on a $0 wallet.
Article is also a good option and graphics design are the latest way to get some few dollars from the internet.
