How would you earn crypto? For you to earn something someone either needs to pay (and no one wants to pay for pirated content), or if it’s like mining where the network pays you, you need to be able to find a way to prove that you are actually sending the expected bytes, and that you are not just faking it or both creating and meeting the demand.

Filecoin that was mentioned is an s3 alternative, you pay for someone to keep your files and also serve them to others. And IPFS isn’t using cryptocurrencies so you can’t make money off it although that would probably be the way to go if you wanted to build torrent+payments.
