For everyone that's asking, I am not going to make it "CPU Only", reason why is to keep it fair.
I can make a few changes to the algorithm where the current AMD/NVIDIA miners won't be able to mine... however since the source code is open source any beginner/intermediate programmer can easily port the changes into the current Pascalminer and mine themselves at an advantage.
So 99% of us would be CPU mining, and 1% would be GPU mining and the GPU miner would get 90% of the blocks and it wouldn't be fair.
Only way to block the GPU miners would be to make the project CLOSED source code however that's not possible...
Its inevitable that every CPU mining coin will become GPU minable
Wish it was possible to limit to CPU only. I love mining with CPUs.
