Bitfetch is a legit service. I got 2 gigs free from the TorrentFreak story, tried it out on a few public trackers, and it worked like a charm. On a well-seeded torrent, it typically DLs at seedbox speeds and sends the contents to an HTTP file with the option to zip. Apparently it seeds back to a 1:1 ratio, but since my trial expired I'm unable to confirm this. Only complaint is the static pricing which is not fixed to a USD/Bitcoin ratio, although the price per GB is at its lowest due to bitcoin's drop in value.
