What do you think about 0.0048GHS/BTC ? Is it worthable for 1TH ?
Well, 1TH is ~1000GH, so 1000*0.0048 = 4.8BTC/TH. Considering you can purchase 1TH for ~2BTC these days, I'd say it's a total loser.
Put it this way, If the CEX price dropped below 0.002BTC/GH/s in the next week, it still wouldn't be a good deal.
