$400 a month for 2 machines? You should be making a lot more... I just got started a month ago as a hobby, using MiddleCoin pool which converts/paysout in Bitcoin, --w/ 1 high-end gfx card(7950), I'm earning 200/month. I just reinvested 700 to start building out my rig, which will have 5x R9 270's and a hashrate of 2250 per machine. I currently make .0125 per khs per day. So this one machine will be worth $28/day.

I do wish I'd held onto my dogecoins though, I would've made a LOT more if I hadn't kept pumping/dumping.

Must be low end video cards. Two 290x GPUs will earn more than that.

Is that number before or after deducing electricity costs?
