It was never said that it will stay cpu only, actually it gives the chance to do some cpu mining before gpu moves in.
(and tbh, there is no cpu only coin... even though supcoin was pretty close to that... but since the dev stated everywhere it was only a test coin

)
Not very true -
Magi XMG is CPU-only.
BSTY also.
Anyway, the algo of ZRC is GPU friendly, Dev said that they will release their GPU miner when there is GPU mining in network...
But dev is VERY silent last few days - the promised pool from them is remaining a promise...
I'm glad and thankful to
suprnova.cc find a way to make first pool and standalone CPU miner,
ig0tik3d for optimising the CPU miner for Win64...
Lets hope that the promised GPU miner will be release very soon, because ZRC mining becomes more and more unfair...
