So I can't mine ZClassic if I don't have ubuntu?
Yes you can, SA has a Widows port.
Okay, but what do I enter as address? Do I just use my ZEC account adrees that I got from JAXX program (
https://jaxx.io/) ?
jaxx dont sipport zclassic. only zcash is supporter. you need an other address. if you are using a pool to mine then you can withdraw to an exchange and sell or keep your wallets there.
btw: i think i have to stop mining. hash rate is too high for my three cpu miners. and yes i have free electricity for them...
