It is amazing, but it has the issue of not having that many user. I2P is great, but because not many people know about it and that it is harder to set-up than going to a torrent site and downloading, not many people use. I2P speed improve the more people use it. One other flow I found is that I2PSnark is awful and there is a need for a better client for it. From my understanding the more you seed, the better speeds you will get, thus it encourages seeding which solves the issue with normal torrent were a lot of people will not seed after a while. I think it is a great idea specially now that many torrent sites are being taken down.
BiglyBT works pretty well as an I2P-capable torrent client. I rarely see it mentioned in posts on I2P for some reason, but I’ve had good experiences with it.
Tried it, way better than I2PSnark, I wonder why it isn’t mentioned on the official page. I2PSnark should be abandoned in my opinion, it is simply awful.
