I don't agree, if it gets to the point where multiple currencies are exchangeable independently (Swap protocol for example) then I can see a use for different variations that have different properties, you may choose one that offers the highest security model and most stable price for savings and another that allows for fast transactions with a reduced security model. It's all gone a bit crazy recently and it's hard to see through the noise, but I do believe that something will come of this technology!
