To be honest with you, I have no idea lol. I only just started mining about 5 days ago.
All I can say so far is, I have my first payout to my NiceHash wallet, but it's only $22. I have to wait another 3 days for a payout until I'll actually be able to withdraw my funds and I can share if I actually get a payout or not. Even though im gonna get killed in fees to lol

But as for actually mining with nicehash, I really like it. Its easy to use, and you can really fine tune it to maximize your results. There are quite a few different scripts you can use, but NiceHash chooses the best one for you. (I choose my own though)
