I was wondering this too as I have been running a comparison between Nemosminer and Nicehash on separate GTX 1080 and NH spends a lot of time on Skein. The only Skein coin I've found so far that doesn't seem sketchy is a version of Digibyte (it's a multi-algo coin, and the main one appears to be Quark, which is only practical with ASIC miners).
See WTM calculator here:
https://whattomine.com/coins/114-dgb-skeinThere are many coins u can mine with Skein. Yes, DGB is one of the better known ones. Also XMY is mineable and I think AUR as well. SkeinCoin ofc the classic.
But there are also some new coins mineable with Skein like LIZ, ARGO, NMS or BTPL.
But which one exactly is so much worth mining that it worth to rent a Rig for 0.0035 BTC / GH / Day ??
