Nheqminer or silentarmy for cuda?
eqm for sure. You can get 220 Sol/s on GTX 1070
220 sol but lock on nicehash , profit is minor , the best is mining directly zcash .
You can also take the bitcoin that you are paid in and just buy ZEC on the exchanges immediately after you get paid... since the NiceHash miner is locked to bitcoin payments.
