[...] You should get your money back or get the full 25 units.

If either of those was possible, I would.


Where are you from?
How much for one unit?

This is for the whole order, so it would ship from BFL.

I'm looking to sell and transfer my order from BFL which I opted to convert to 24x 60GH Singles from the original 1500 GH Minirig. Just want to see if I can sell the lot in one go.

Will escrow for the transfer of the order.


Please PM me if interested  Smiley

Hope this works out. I hear rumors that BFL is in a death spiral now.

At the current pace their Singles will catch up to my order date by the end of the month. Might have to just convert to Singles and sell them one by one. Was hoping to do this all in one go  Wink

I think you are wrong, even if you convert you rig to singles they will start shipping just when they get to your rig order in the shipping queue, and they wont send everything at once, your shipment will divided on 3 small ones of 3x500 or 8x3.

I am not 100% sure but it is worth checking with them.

They are not holding back the converted rigs on the count of held up standard rigs that are ahead of you, as I understand:

"We moved a lot of MiniRig orders this week by putting the boards in Singles cases instead of the MiniRig case for customers who have opted for this configuration"

So if you "opted" for singles, they will ship you singles according to your pay date, along with the rest of them.

Guess I'll find out either way.

You have two options, put all your income back into buying more hashing power to keep up in a perpetual an never ending race. Or you get BFL to give you 14 day contracts that terminate and re-rate at the end of each period. (BFL will never do this!)

Your choice! (are pretty bad, huh?)

You missed a third choice, and arguably, the wisest one.  Wink

7  Economy / Computer hardware / Re: [WTS] 1.5Th/s (3x 500Gh) ASIC Miner BFL order #171XX - Feb 22 2013 - 170 BTC OBO on: September 16, 2013, 07:15:53 AM
I'm looking to sell my 1500Gh Mini Rig order. Even though they are slowly shipping, now that it's three separate 500Gh units, I can't host them all.


So are you asking 170BTC for 1500GH/s package, or one 500GH/s minirig?


This is for the full 1500 Gh order. You can even have it shipped as 1500 Gh worth of Singles according to BFL.

I'm looking to sell my 1500 Gh/s (1.5 TH/s) BFL order. Even though they are shipping, I can't host all of them.

Order #171XX, placed and paid for on Feb 22 2013.

You can have it shipped as 3x 500 Gh Rigs, or 24x 60Gh Singles if preferred. Note that their Singles are shipping a lot faster than the Rigs right now.


Asking BTC 155 but open to offers. Will escrow through John K with release once the order has been officially transferred.

Feel free to PM me  Smiley

In all honesty, I think PPC has the strongest chances of this. It's got the best inflation model, the greatest security and is energy neutral. Plus, it's got one of the most brilliant devs I've ever seen.

I think Bitcoin will reach about $400 max and then slowly decline as a result of PPC's influence.

If bitcoin stays around long enough then there is a good chance that bitcoins as valued in dollars will reach $1000.  The trend in the denominator (usd) is down.  For example if you plug today's price of bitcoin/usd into a government inflation calculator you find that it took 46 years (1967-2013) for $143 to turn into $1000 just from dollar devaluation alone.  Obviously if the intrinsic value of btc increases (e.g. from more people trusting and using it) than that will accelerate the trend.  In short I think there is a good chance bitcoin will either reach/exceed $1000 or become worthless depending on whether or not it remains viable as time progresses.  I personally hope that bitcoin lasts. Bitcoin is a huge step in the direction of a more free society!

During an economic downturn, a lot of money moves out of fiat and into precious metals. However, after it was revealed that paper gold certs are completely un-backed (see "Germany gold federal reserve"), the only sure way of having gold is to hold gold bullion, which is becoming harder and harder to find/ship/verify/store.

Bitcoins are weightless, virtual, and unforgeable, at the expense of being more volatile.

If/when the economy tanks, bitcoin will reach FAR beyond $1k.

LTC going nuts

This has happened before. LTC dumps often follow BTC crashes. just wait.

You mean the opposite actually. LTC pumps often follow BTC crashes.

BTC Crashes so people hedge to LTC? Or LTC gets pumped and people exit crypto (BTC)?

One day, the opportunity to have bought sub $1000 bitcoins would be like buying a 400oz gold bar for under $1k.

Some day...

18  Bitcoin / Hardware / Re: Anyone demonstrated a 28nm ASIC mining bitcoin yet? on: August 23, 2013, 01:41:28 AM
I would venture to say that HashFast's implementation of 28nm process is not as good as it gets, and is more of a race to the market type design.

I think Cointerra will beat them in electrical efficiency judging by their resumes. "CoinTerra boasts a highly experienced engineering team of semiconductor architects and designers who have previously designed some of the world’s highest performance CPUs, GPUs and chipsets for NVIDIA, Intel, Samsung, Qualcomm and Nortel. Having worked on several generations of low-power mobile devices, our team brings tremendous experience in power efficient circuitry, design methodology and implementation to the exciting new frontier of Bitcoin mining. "

They are claiming "significantly less than a watt per Gh/s" on their 28nm product.

Considering we already see <0.7w/GH on 55nm parts, qualifying the claim with "significantly less" as rather arbitrary for 28nm tech. I want to see these come down to fractions  Grin
19  Bitcoin / Hardware / Re: Anyone demonstrated a 28nm ASIC mining bitcoin yet? on: August 22, 2013, 10:27:02 PM
I'm not so sure there will be that many incremental changes made to chips once they start to hit the process limit. I say this as I expect the margins on chips to become so slim that it would be financial ruin to invest in the NRE for another 28nm chip once you already have one.

I guess it all depends on how "good" existing designs are.  Taking HF just because they provided die size, hashrate and power info.

Quote
One 18x18mm die is able to do 400 GHash (nominal - more overclocked**)
   Hashing per square mm:
      18x18mm = 324mm^2
      400 GHash / 324mm^2 = 1.23 GHash/mm^2

Reported power consumption is 400 GH / 250 W = 1.6 GH/W.

So HF claims 1.23 GH/mm^2 and 1.6 GH/W @ 28nm.  It remains to be seen how "good" those are for 28nm.  Are they very good, or barely adequate?

If their simulations show an improved version is only marginally better (say 1.4 GH/mm2  and 1.8 GH/W) I agree it wouldn't make sense to try and squeeze out more efficient chips.  On the other hand say >2.0 GH/mm^2 and >3 GH/W) are possible.   Once we get multiple vendors with stats based on real silicon we can start to get a better idea of relative efficiency.




Just responding to say that I agree on all points. I imagine the first 28nm designs may be more safe than elegant to minimize risk, leaving performance on the table. 2014 will be exciting, 2015 maybe not so much.

Maybe in terms of bitcoin mining. But the snow globe's only just started to shake as far as crypto-currency goes  Wink

BFL is predicting their 28nm chips will use barely less W/GH than BitFury's 55nm chips, when they should be at least 3x better than BitFury, if their design was as good. BitFury's 28nm chips (if they plan to do that) ought to be awesome.

Without getting into BFL's 28nm plans, it's boggling how their 65nm design is eating 4w/GH even after their epic development time, whereas this 55nm design is well under 1w/GH and seems to have come out of no where.
