I'm finding it difficult to understand how anyone manages to mine profitably unless they're getting "free" power or using ASICs. For those of us with gpu rigs, scrypt/scrypt-N/X11 are all money losers even with the most frugal gpus (like Maxwell-chipped Nvidia cards). My power is relatively cheap @ US$0.10 per KwH and my R9 270/280 cards and Nvidia 750ti cards are in the red for every currency I've crunched the numbers on. So I've just left my gear powered off for now.
How do you guys do it?
