Dual mining still works but not Profitable and more electricity drawn in the process, years ago dual mining was very profitable and more advisable too but not anymore, ETH+ZIL is still a thing but that is if you don't pay huge electricity bills
How about ETH+HNS do you think it will still eat more power?
Or it's enough to mine a single coin which is ETH?
I'm actually paying with high Electricity rate here in my country and trying to reduce the power just to stay mining with ETH.
It eat more power without higher profit. Right now i`m mining ETH+ZIL, it gives few dollars more, but yesterday i decided to think about it in such a way:
Ezil pool have just 1% of ETH nethash. That`s why he catches 1 block in 100. For a long distance with the same reward - it doesn`t matter. But yesterday i saw a wave of blocks with huge reward. And in such a case Ethermine catched 30 blocks, and Ezil just 1. And in such a moment dual mining becomes less profitable.
