When the first leak occurred a few days ago, the price of a cube was listed at 1.99 btc. That is was around $450, a great price for 30Gh/s.
Today 1.99 btc is $622. You are getting close to what you need to pay for a 30 Gh/s BFL box on ebay. By this weekend, if btc keeps rising, it may be hopelessly overpriced.
It's really not a great price.
Cointerra for January delivery is 2 TH/s at $6000, or $3/GH. The cube - at the original $450 price point - is $15/GH.
Do you think you can squeeze $12/GH out in a couple of months? Good luck.
do you think cointerra will deliver on time.
