For the time being, Ethereum is the best coin to mine, even profitable at electricity of $0.2/kWh. But the price might drop and make it unprofitable.
If you have the hardware already, I agree Ethereum (ETH) is the way to go right now for home mining. A close second is Expanse (EXP), it is trading about 1/12 that of ETH, but you can mine about 15x the amount of EXP per day using the same hardware and software. However, Expanse is a lot more volatile, so you may want to trade any mined coins off right away if you are mining strictly for profit as tomorrow the price could collapse.
