ZEC mining looks profitable but once price goes down its the same fate
factor in 30-35% lower power draw and even if the btc payout is eventually the same as eth per rig it still makes more sense to mine zec with electricity factored in.
there is also total power draw if thats what limits you. someone with say 100 amps as upper limit can now use 30% more rigs for same amps.
In the Claymore V1 to V7, the power is 30% lower than the ETH mining. But now it is just 10% lower.
yeah and its very hard to undervolt for zec vs eth since zec uses alot of gpu clock
witch in turn means higer voltages for and core clock above 1200
unlike eth where you can mine at max power with under 1100 core even
