After a few Google searches, I found a lot of good reviews about Nanopool and issues about dwarfpool.
Took this from reddit:
I'm two months in on Nanopool and haven't had any issues and happy. The thing I can't figure out is since I've started, it continues to take 4-5 days to mine .2 ETH even though I've added 50 Mh/s (3 Gpus) to my rigs. 1 rig running 4 rx 580s on Ethos and another 2 1070s on windows for a total of 170Mh/s... I keep track of my earnings and back when I only had 1 rig with 3 RX 580s it was still 5 days. Anyone know what's going on?

Nanopool seems like a reliable earner, good stats per rig, etc..
With dwarfpool I could use my stratum proxy which gives a few extra % income (about 7%) so I am using that.

Anyways, I would just create a thread in the "
Mining (Altcoins)" or "
Pools (Altcoins)" board as people should be able to answer you better there.
