I don't think there is any good coin in the central processing unit except Monroe, anybody agree?
There are other CryptoNight coins out there that can be potentially more profitable than Monero for CPU mining temporarily, but thats essentially true.
If youre mining with an Intel CPU on Nicehash, though, it seems to default to HODL since Intel CPUs typically arent that great at mining XMR with their small L3 cache. Seems like its only been on XMR for a short time this month if youre theoretically mining with an i7-6700 or even a 7700K.
