I had been using bit torrent for a few years now and there is where I get my movies to watch and then delete it afterwards as I have no use for it anymore. Bit torrent is a good source of files but be careful though because some of them have malwares that could harm your PC if not your information so be careful.
When I download files like in movies I just untick/tick the files that I do not want like some text files that is not relevant. Then you must seed though so that after dowloading others also can get a much better download so the file will stay alive and the exchange of files will become faster. It is a peer-to-peer network of sharing files so we need each other, seeders and downloaders.
But traditional bit torrent doesn't pay you while you are seeding while you just get a consolation by getting a free file while in joystream app you can get paid by seeding a file after downloading it. You get paid in Bitcoin cash so it is an excellent way of earning some extra cash. I actually haven't used it yet but I will try it now.
