Some incredible mining profit spikes on Zcash since last night but they only last a few minutes. My rig makes about $8-9 per day the last week mining ETH/DCR or Zcash and last night Zcash spiked to $11.50 for a few minutes.
I'm even mining it with my AMD cards. I did not realize how little power 570s and 580s use to mine Zcash compared to ETH and ETH/dual mining. My 4 AMD cards are using almost 300W less when mining ZCash vs ETH/DCR! That works out to about 75 cents per day saved on power and everything runs much cooler. So now I am factoring that into my decisions about what to mine.
Is that $8-9 pre or post-electricity costs?
That's gross profit, electric is about 20% of that.
Since Zcash has dropped back to $200s in the last week I've gone back to mining ETH on my AMD cards.
