So you are trying to market another type of mineable coin that can be used outside of Toribash for purchase of other services but never actually will be and no one will trade in it because it's actually worthless? Not being a dick but it sounds like Dogecoin and other spin offs such as that.
Just stick with TC for the game currency theres no need for a currency that can be used outside of the game, it is a game after all, a lot of children play it.
EDIT: Came across hot headed on the idea as it is after all meant to gain funds for Toribash Next - wouldn't it be a good idea to have some sort of reveal of how far you have gotten / what we are to actually expect of a finished or closed to finished product or even a started one? Have just a kickstarter/other way of form of donation instead of wasting time with the coin idea maybe?
