Check out whattomine under the GPU section.
ETH/EXP are Dagger Hashimoto based coins and can dual mine with coins like LBC DCR and SIA. On whattomine this is called ethhash.
GTX 10 cards have an edge in ZCASH based coin mining. That algo is called equiihash on whattomine.
Coins I mine with my GTX 10 cards are: ZEC ZEN HUSH and KMD.
also, can you please tell me which miner you use for equihash?
EWBF miner has been the best for me for GTX 10 cards mining equihash.
You need to understand what is happening when mining to know how dual mining works. I will give you brief examples.
ETH - Ethereum, Expanse and others are compute light, memory heavy algorithms and most miners have extra memory overhead unused during ETH mining. This allows for dual mining of a compute heavy coin with a light memory footprint, like LBC/SIA/DCR/PASC.
ZEC - ZCASH, ZENCash, HUSH and KMD are all equihash coins and that algo is both compute intense and carries a beefy memory footprint. As far as I know, there is no dual mining with equihash.
