Title says it all.
I saw this question, and was thinking probably not.
It isn't illegal to share a file with Bittorrent.
That's all that's happening here. It's a file called
movie.mkv. It might a super-illegal leak of the next Star Wars film, it might be something the OP has created. Or something in between. My point is they could have full rights to do what they're doing.
More than that, they appear to be sending it to themselves. Even if it were Rogue One, personal copying of a file you already have is a long way from criminal redistribution.
That is all to say: Chill out. Answer the question on its technical merit.
