With Cointerra's 2 TH/S monster set to release in February (assuming on or almost on schedule) will this be the best play in the near future?

Even factoring a 500% increase in difficulty by mid-march 2014, you are still looking at $160 a day with Bitcoin at their current price in the $390 range.

It's clear to me that any lowly GH/S (even Avalon's) will be hopelessly obsolete if they aren't already.

Is this a viable option going forward? Yes, a lot of risk, but $3 GH/s can't be beat as far as I can see.


 
 I'd appreciate useful feedback, and if anyone has any additional information on this, or about Cointerra & their reputation, warranty, replacement, customer service.

Thanks.
