It seems animesuge.to, anix.to and aniwave.to closed down with the exact same message, though there may be a few other sites that closed down in a similar way.
Pirate websites like this usually rely on the shadier ad networks baked into these kinds of video streaming sites to make their money.
There's no financial incentive to use BitTorrent based streaming, and if they did I feel the torrents would die rapidly just due to the amount of leechers with barely any seeders to offset the ratio disparity (Unless some kind of webseed was available ?)
You won't get caught torrenting. This has nothing to do with encryption. You are at the mercy of the site owner, who has a lot of server bills and can make money by putting viruses on your computer.
