Let's say I'm on suprnova instead of nicehash... Would i get less zcoin?
They are not only taking big fee , but also you are paid in btc from those who rent your hashpower and they always rent less than market price to make some profit , nicehash is for newbies, if you want to mine zec really then you should join a good pool with good luck percentage like flypool and convert your coins to btc through exchanges.
