Wow, Cointerra "delivered" but not really...

Overpromised and undelivered big time.  I'm beginning to sense a theme in the Asic pre-order world...

Here's the funny thing: BFL built a chip that they thought could do 4.5gh at 10 watts and found it could do 4gh at 15. They redesigned their boards, and sold the jalapenos on Single board frames (which were built for 8 and cost a lot more) while delivering the 30gh units on totally redesigned boards. Took a few months, probably cost a lot, and people bitched them out.

Cointerra had a worse problem (25% less *and* more power) and instead said screw it and delivered substandard systems to the users. Didn't cost Cointerra a cent.

So who really is the bad guy, and what is the right moral decision here? Do it right, spend the money, and be pilloried, or just say the heck with it and ship for nothing?

the right moral decision always lies with the consumer. don't do pre-order. simples. if the consumer wasn't in such a rush to ramp up the network hashrate, these companies wouldn't get away with this.

I have only bought miners from pre-orders, and all those miners gave me money. As long as you dont put your pre-order into a scam vendor, you should be ok.

And about the main topic of the thread (about Cointerra 2TH/s miner), yes, it will be profitable. Not crazy profitable as ASICs in 2013, but profitable anyway. If your TerraMiner arrives in May, dont expect to recover your investment until late 2014.

As a guideline you shouldnt buy anything older than 28nm asics (most popular 28nm asics: KNC Jupiter/Saturn or Cointerra's 1.6TH TerraminerIV).

40nm, 55nm, 110nm, 155nm might be cheap, but you will need to power those things down by the end of 2014.

Here you have some info about why mining is still profitable this year:
