Will it cost money to download bit torrents

No, downloading a torrent is free, but really, when you download something off the Internet, it uses your Internet downloads. So when you use those downloads it is basically using up the downloads you pay your Internet company for. So the answer is logically yes but is not allot. Downloading torrents is possibly illegal and could be hazardous to your computer. Downloading a torrent of copyrighted material could land you in legal trouble.
