We currently have a couple of CPU miners running. First off no they are not profitable however the mining does help recoup some of the cost of the machine running 24/7 anyway. We’ve tried a couple of CPU miners for cryptonight algorithm and the hash rates don’t really vary that much one way or the other. The is one thing that makes one better than any of the others we have tried to date. Stability. XMRIG without question is the most stable that we have used.
