I currently buy hashpower from Nicehash and make a small profit.  I wrote the below if anyone is interested.

I came across this post as I was trying to figure out why none of my nicehash shares reflect on zec.suprnova.cc

I'm not going to labor the point but I experienced the exact same thing as described in this post.  I bought around 4.5MH from Nicehash for an hour, and the order successfully kicked off and showed shares being submitted.  I could see my hashrate reflecting on the suprnova dashboard, I could see my estimated earnings reflect (initially as 1.3 ZEC), then the estimated earnings started dropping and eventually went to zero.  The pool isn't showing any sign that I ever allocated any mining power, no transactions, no earnings ... yet real time I could see that my shares were being picked up.  I did contact suprnova this morning via the "Contact" option on their website, but no reply as yet.

So in my case, that little experiment cost me 0.075 Bitcoin.

To the pool owner, the following comments:

- The ZEC suprnova home page and landing pages all show the following: "For Nicehash use zec-eu.suprnova.cc:2143", so that is exactly what I used when I configured my order in Nicehash (along with my username and password obviously).  That comment (to me) indicated that the pool caters for Nicehash orders specifically, as in it is a good idea to use this pool for Nicehash orders.

- If there are known issues with running Nicehash orders against this pool, or if that comment only applies to the Nicehash miner and not purchased hashpower, then at least clarify or remove that comment from your landing page.  ...or state on your homepage that Nicehash orders against the pool are not supported, or might experience issues, or something to that effect.

- I understand Nicehash is involved, and the pool is involved, and I am involved, so it is difficult to figure out technically what happened.  However, I can see that Nicehash is still correctly reflecting the times and hashpower, I know that suprnova was reflecting the hashpower correctly and was showing the same hashrate as Nicehash when the order kicked off (I checked before I left the order to run and complete), the only issue is that suprnova has since "forgotten" that I ever existed.  It's difficult to believe the issue is somewhere other than the pool.

- Never mind log files, just compare the rewards paid to the pool to the earnings you allocated for the last 24 hours.  There should be a nice big "hole" of at least 1.3 ZEC there (or more?)
