No way. Torrents files, movies or MP3s are too big. And you cannot insert a file in the blockchain.
You don't need to store the files themselves, only seeds, which usually are pretty small.
Actually you only need the magnetic link.
Even if it is just the magnet link , I don't think bitcoin should be used this way. It is more for a role of Storj or maidsafe.
No one can define how or for what bitcoin is used, if there's people willing to put torrents on the blockchain and other people wants to get them from there, it will be done.
