Hello everybody!

I feel a bit lose, I bought my first and the only one rig in January. It has 4 1080ti MSI and 3 1060 (6GB).
I started to mine zClassic I hold to get btcp so my 2 month inversion was fucked up. I don't know too much about trading and I didn't expect that to be honest.
Later I've been mining ZEN, I use to check whattomine and it supposly was the most profitable coin. I'm done with ZEN but I don't know what coin would be better to mine.
My gpu's aren't overclocked because I didn't see any good config, if someone could me suggest a set up, I will be really happy.
As well if someone could say me what are they mining and how do you search coins to mine with good profitable.
1060 GPU's are mining only ETH.
Thanks in advanced! I hope to hear from you!
