Besides, you can earn currency from just seeding the torrent- presumably there would be a way to download some initial torrents for free and then you can contribute to the network directly without needing to get a wallet or set anything up.
It’s on the web as well, so it could be as seamless as YouTube, only you’d have a small currency counter that goes up if you leave the tab open, and you can either spend that currency by downloading or withdraw it by selling it to other users who would rather pay than seed.
