Is that even possible anymore? I've seen so many coins promise "CPU only" mining only to be toppled down by GPU miners and even FPGA's!
Is there even one coin in that vast sea of cryptocurrencies that is truly profitable for CPU mining?
I've jumped from Quark based coins, to X11, to Scrypt-N, and now, Momentum. Is protoshares and memorycoin even profitable anymore?
Try CryptoNight, like XMR and BCN
My measly i5-520m from my laptop even gets 40H/s, my simple i5-3470 from my desktop gets 110H/s & my gtx750ti get 240H/s.
So I think that one has a really nice CPU:GPU ratio.
