Why use Nicehash, especially being a member of this forum? It has tons of information to help you make most of your card.
just gathering information before I decide what to buy for my next rig. rx 580 is not an option anymore now that eth can go PoS any day.
read from a local forum that you can get $2 a day per card from there.
If I was choosing what to buy now I'd go for a mix of 1070ti and 1080ti. They have different memory types and can compliment each other on various algos.
