Right now eth gives only $1.20 per card and if the difficulty keeps rising then soon will be $0.50 and then 0.
Even on NiceHash it's still $1.88 each for stock RX480 4GB cards... no BIOS mods... mild OC.
I don't normally mine Dagger Algo or even on NiceHash but just checked to verify earnings.
Would I buy a NEW card at the CURRENT prices for that ? Heck no... but us folks with cards already it's FAR from dead.
