You will probably smile at your own question when you have realized what Nicehash is.
I think like that's
if @OP not knowing it yet, what is Nicehash:
you no know how to work nicehash
nicehash work rent your hardware and mining the best profit algorithm
then send your profit at bitcoin
so nicehash not mining direct coin
