I mainly mine zcash with a total speed of about 950 h/s.
I actually have the money to buy a fourth card but I'm still thinking if it's actually worth it anymore !
Difficulty is going up like crazy today. It reached ,for the first time ever, more than 10 million.
If you head over to whattomine.com you'll find that with that difficulty you'd get $2.57 a day with my rig (which is about $0.85 per day per card which costs $400 !!)
Still thinking about it. I'm also thinking of mining new coins that haven't gone mainstream yet but it seems like some sort of a gamble to me (since I'd be still paying for electricity and just hoping for it to rise).
