What are you mining to get that?
But, seriously, $15 a day per card? For a few days with a real exchange?
with 2 real exchanges
SPR and NXS I guess. I got more than 18$/day per 1080Ti
Are these any good now?

68 coins on 6x1080Ti rig per two days. It is approx 17$/day per each single card. It is awesome.
I can`t understand how it is. Calculator at
https://nexuspool.ru/ shows really small profit. On your screen i see just 1450Mh but to get 66 coins your ought to have about 6Gh.
