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.
