I'm pretty sure the best thing you can mine right now is Sparks on bsod.pw. I have been getting about 1 coin per day per 1080 for close to $20 per card with current btc prices.
Edit: should be per 1080 TI not 1080
its only 20$ per day per card if theres somewhere to sell it, does SPRks have a good exchange?

lol
it had coinsmarkets but they look to be kinda dead at this point

stocks.exchange showed up about same time as coinsmarkets so i dont trust it either :/
