I mine ETH on my gtx 1060 rigs, too lazy to research and switch, I believe ETH is the most profitable coin for gtx 1060 and 1070.
I only mine ETH with AMD cards. I'm mining Luxcoin with a 1080 TI, 1080 and 1070. Seems like a coin with a good Dev team and roadmap. With a 1070, you should get ~$2.40/day mining LUX vs ~$1.80/day mining ETH.
