even 1 month ago, I was earning $1.5 from a single gpu. Today $1 is hard to earn. Still people are mining ethereum ?

with dual mining it's still above $1.5 for a 1070, actually nearly $2 depend on electricity

what about 1080 is it still profitable ?? i was planning to buy a couple specially for this . if its worth it i will go for it ... please help

The 1080 is not good for the Ethereum mining. It is GDDR5X memory, that is not suitable for the Ethereum mining.
