It's been 13 yesrs after this blog was written. Does the claim still holds true?
Yes. It is better to use i2p for bittorrent. Now qbittorrent it is compatible.
Thanks. I was hoping 13 years will bring some improvements but sadly seems like not.
I don't understand what the down votes are for. Disagreement? What's wrong in hoping for improvements in a 13 years gap? I understand and agree that BT over Tor is bad, but two doesn't conflict.
hoping for improvements
There have been improvements, just on the fronts you haven't been looking for. Also, if I am correct, torrenting over Tor would be painfully slow compared to normally doing it or via a VPN. It is not worth the hassle.
The way it was worded might be seen as improvements to torrenting on Tor instead of improvements to i2p.
