Just started following this post last night.... Switched over to SIGT.
Starting to think I missed the SIGT boat... Using CCMiner-Skunk 2.2 with 8x 1080ti's (2 rigs) I am only getting around 130Mh/s on each rig.
Looking at my stats on Yiimp I am getting about half of what "What to mine" has me listed at on that hash rate.
From what I see I am basically making what I would with the rigs pointed toward Zec?
better late than never.
if you want you can also buy the coin directly instead.
one of the reason you get lesser coin is because as time passes, more and more miners are adding to the hash rate, increasing the difficulty. in example you just added to the total hash rate just now.
another thing is if I understand correctly, you are only getting 16.25mh/s per 1080 ti card? if yes, there's a problem on your setup as I'm getting 50mh/s per 1080 ti card of mine.
