Surely a coin limited to use on tor will hinder it's adoption? I guess maybe coins will have to use tor in the future if governments try crack down on their useage.
Well, its not really limited, you can use it with Tor or I2P and after the implementation of Zerocoin it's truly anonymous anyway.
The coin is in existence already by the way. I only made the post so I could post on bitcointa.lk which can still be used in China.
