there is 0% risk until your country makes a law that prohibits any and all P2P communication. That would not only break torrents, but would thwart signal/telegram/whatsapp calls too, Jitsi meetings, probably google meet and zoom too, as all those use P2P traffic for performance.
So far there are only such laws in far east countries, and the official java I2P router is smart enough to not participate in routing when you are in such a place.
Also, I think for routing to work you need to open a port, without it that won’t be done.
