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$0.10 per KwH and my R9 270/280 cards and Nvidia 750ti cards are in the red for every currency I've crunched the numbers on. So I've just left my gear powered off for now.
How do you guys do it?
I think it's really hard with the current prices of the BTC and the values of the altcoins. I even pay a lot more per KwH, so that's why I quit mining.
One way you might get some profit is to mine abandoned altcoins (with a low difficulty and hope they gain value one day) or mine really new altcoins. In the very beginning every altcoins is quite easy to mine.
Also take in mind that currently mining for example LTC isn't profitable. But, is the LTC is worth 50$ in, for example, January, then your mining actually was profitable although it didn't look like that when you were mining. (As the 0.1 LTC you mean now is worth $5,- then instead of the current $0.50).
Yeah, I'm not willing to roll the dice on abandoned coins or fly-by-night new coins. Oh well. It was fun while it lasted. I suppose I should be happy that my gear paid for itself and made me a small amount of $$$ before the market tanked. Perhaps it's time to start liquidating my cards on fleabay.
