I think you should go bitmine place order and seen the amount of Bitcoin then look at bitpay.
There is a big difference

if their exchange rate USD/BTC was really high then this was excellent, but I think you meant the opposite,in other words really low, in this case I call bullshit because they use Bitpay, and most of manufacturers and merchants uses bitpay, so at the moment you placed your order you would pay for the same rate and it doesn't matter if it was cointerra/BFL/hashfast/bitfurrystrikesback/bitmine.....


because bitpay exchange rate is known and anybody can check it before placing an order and when placing an order https://bitpay.com/bitcoin-exchange-rates

there is still nothing official. It's just somebody writing something in a forum.

I mean if there really problems, why don't they write an official statement to all customers and on their website?
It's just ridiculous what is going on. There is still no prove what so ever they are doing anything.
Fine they are maybe working hard 24h/7d a week. But we payed and they don't deliver anything.

It's just in interest of both sides and wouldn't take much time at all. But since Bitmine AG is just quiet, what is happening right now makes the hole thing look like a big fraud.

I have the same experiences with butterfly labs.
They don't give a shit about customers. They cancel my order and after wanting a refund they uncancel my order.
Also they didn't answer to my emails so I lost more than one month from first order queue, etc.

About bitmine they didn't aswer my email i send 3 emails.
Their exchange rate USD to BTC is insane high. So I decide not to buy from them even I can go there and pick it up.
Because when I can get this item, 1THash will be almost unusable.

ok than we sit and wait for people to get what they pay...
I expect more professional behavior from someone which I give 6.000$

except that this company really exist and members have visited them before....

If people forget there have been companies in usa on some address where nobody was. Companies with phone number and also some pictures of people which doesn't exist.
Somebody should check company by going there.

Occam's razor does not agree with you.
It is way more likely that the people who are known to be building this equipment are simply maximizing their profit with it than that a secret manufacturer exists who is throwing all this juice into the network.
Your theory is way more 'conspiracy' based.

wait a minute, the end of the next week !!!! this is 9th of February !!! this is a 2 diff. retargets.... and add to that the shipping time !! now if cointerra start shipping this week we are seriously doomed

.. why do you ask for a statement here 
I guess all customers from bitmine.ch should have the phonenumber .. just call .. and let us know 

Generally my impression is that the chip is well in the announced specs, but given how sensitive folks are to facts, I understand why Bitmine waits for the final chip to present binding numbers.

Well, this OTOH I can comment on, since I am testing the chips.

Several things to take into account here:
1) Those preliminary power estimates were given based on GF's numbers on their processes and simulations. Those following the chip developments over the past 2 years know how those estimates can be quite in line (KnC) or 400% off (...). Whether the final chip will provide those figures remains speculation until you actually test the chip and measure the numbers.

2) The samples we have now under test are inferior re packaging compared to the final ones. This affects thermal properties as well as voltage supply restrictions. As a matter of fact, we were limited in the measurements we could perform so far and need to wait for the final chips for the remaining ones.

3) The numbers we were able to turn from expectations into facts are very good. At nominal clocks (800MHz) we pull like 1.1J/GH from wall. Deducting PSU and DCDC losses and considering sample chip inefficiency, we are at 0.6-0.7 J/GH at chip. While with the above limitation we can not yet test the other modes (turbo / low-power), we nevertheless pushed the chip to 1GHz clock and measured the expected 32GHps.
