Just use www.allchains.info - it has the most reliable method. Currently predicts 243,000,000 for next adjustment. Not impressed by it. Its now predicting 254M, and thats most likely still 10M lower than what it will be. Dot-bit has been fairly consistently predicting around ~265M for some time now. It seems like allchains is using the old algorithm that dot-bit used and ditched: "New used algorithm to estimate next difficulties is more accurate than traditional estimations, especially in cases of great difficulty change. Old estimations are still available on the old difficulty page." http://dot-bit.org/tools/nextDifficulty.phpTheir old algo gives the exact same result as allchains. |

Not all Bitcoin ASICs are the same.
You can't compare friedcat's first gen ASIC and bitfury's second gen ASIC to HashFast's 3rd gen ASIC.
28nm is nothing like the larger feature sizes, 1 billion transistors pumping out 400GH/s is nothing like tiny previous designs.
Cointerra's credentials are most certainly an argument against them.
Their expertise is throwing the IP Samsung licensed from ARM onto a SOC. Low power, low gate activity ratio SOCs, not huge hot high-performance 3rd gen Bitcoin ASICs.
Neither Friedcat nor (afaik) bitfury ever even designed an asic. Any asic. friedcat did get help from some people who did with experience in... embedded soc's. This "high power" "400 billion transistor" FUDis just that: FUD. Copy pasting a single hashing core a few hundred times isnt exactly the hardest thing on the planet, especially not when compared to laying out a modern SoC with half a dozen clockdomains. And if anything, designing for low power is what really takes skill and experience, its the hardest thing there is. High power is a pretty simple problem by comparison. Lastly, designing for 28nm also isnt meaningfully harder than for other process nodes. The fabbing is a different story, but thats done by tsmc/GF/whatever. Being ex samsung, they are likely the only bitcoin asic designers with 28nm experience. Anyway, its clear you have an agenda here, and Im getting really tired of this mentality of rooting for one company and fudding all the others (wtf is up with that?), so your ignore button is about to get a bit more yellow, spare yourself the trouble of answering. |

There's a brown to the lower dirt there. From NY, the dirt on LI, except at the shore or out east, was a deep rich dark soil loaded with earthworms. Early in this planet's history there was a collision with another, smaller, planet and the moon was formed. I'm convinced the dirt down here in the south is from that alien planet. It's red as Mars, lies dense as red brick, and has a thin layer of top soil completely unlike anything on LI. This has to be alien what I'm living on. What's up north is the real earth.
Sounds like SR closure didnt prevent you from scoring... |

yeah because designing a bitcoin asic is so complex, asic design neophytes like friedcat and bitfury could pull it off. Heck even BFL did it, eventually.
Seriously, you're being ridiculous. Nothing guarantees CT will deliver on time and on spec, but their credentials most certainly isnt an argument against them.

The price had better explode. Those of us with Jupiters need to climb out of a $7000 hole.
Ah dont panic. If it doesnt work out with KnC, just try with hashfast. Get some "miner protection" while you're at it, and order some cointerra's just to be sure. You know the saying; if you're in a hole, dig deeper  ex-miners and bitcoin holders like myself thank you for your sacrifice in making our network more secure! |

With efficiency 7w/gh/s whole network uses somewhere between 10 and 20 MW. And most of asics are more efficient than that. That's nowhere near small nuclear power plant
Isnt it ? http://en.wikipedia.org/wiki/List_of_small_nuclear_reactor_designsAnd its only going to get worse, much, much worse. CPU's, GPU's and FPGA's were inherently expensive because of their complexity and different target markets; that cost (to the miner) limited overall hashrate to well below its electricity cost. Bitcoin asics are dirt cheap to produce, and have no value other than for mining, so in the long run, their price will come down to the point where its irrelevant and nearly all mining revenue will be spent on electricity. Energy efficiency of these asics doesnt matter for the overall picture. More energy efficient designs would just lead to a much higher network hashrate, but at the same overall power consumption as a very inefficient (but comparably cheap to produce) asic. Only electricity price and the bitcoin value (and perhaps transaction fees) will determine how much electricity the network will use. And its not gong to be very green, especially if bitcoin value rises to thousands or tens of thousands of dollars as some think. |

The first question is: should you buy any asic? The answer is, if you expect a profit, you should NOT.
|
|
|
|
On the other hand, did any other bitcoin asic company consider broadening their scope, like AM revealed in their last update?
bitcoin asics is a once in a lifetime opportunity. being able to develop a chip so simple it takes only a few engineers a few weeks to design and selling tens of millions of dollars worth of them at 10x or 100x intels margins, I've never seen that before and don't expect I will ever see it again. |

. Anyone can click on the "last posts" in the profiles of both of you and see that you are heavily shilling for KnC in their thread,
wait, what lol? me a knc shill? rofl. please post my best knc cheerleading and I will temporarily unignore you. |

probably somewhere between 2 and 5 million dollar. first batch is 2 PH, do the math
|

it's a sunk cost all right, and easily covered by the first round of preorders.
|
|
|
|

spare me the economics 101. you said they couldn't sell it any cheaper because of "all the stuff that's in the box", not because of sunk costs. in reality, they can produce these boxes for little more 10% of their price., and sooner or later they will (have to). sunk costs won't change a damn thing about that, they will only factor in their profits/losses.

so you think it costs 1000 plus asic? in that case I'm not even going to.bother disprove you. what do you think the production cost of such an asic is?
|
|
|
|
Interestingly it went down for a few hours, just when other KnC hosted customers reported their miners to be down. |

Anyone worked out how many kWh per BTC? I guess the average power consumption would be over 2watt per GH/s atm. must work out to well over 500kWh per coin when you factor in dater center aircon.
RIght now hardware cost is still a far bigger cost than electricity, but given the nature of asics, that wont last very long. At some point, the electricity cost to mine a bitcoin will pretty much equal its market value. As long as it considerably cheaper to mine than buy, more people will join the network, its that simple. |

They should offer even lower prices now. I want to buy a Terraminer IV. Gimme $2/GH and I'll get 10 units or something.
While it may be possible for them to sell you chips at a lower price if they choose to, i really doubt they can sell any 'systems' lower than $3/GH because of all the other stuff thats in the box (case, power supply, cooling (fans, radiator, pumps), pcbs, controllers, sockets, cables etc). LOL. You dont really believe that do you? You can buy barebone PCs which contain far more PCB, cables, connectors and stuff for $150 in retail. A liquid cooling kit from Intel costs $45 retail. |

That is a long ways out. They got themselves covered by having you pay a lot up front then and you getting little in return later for all that extra hashrate which doesn't come till much later.
IM not saying it will take them that long, but clearly the ToS protect Hashfast far better than the MPP protects its customers. |

I see it as just another form of preordering. Almost double the price for <=4x the hashrate delivered >3 months later.
Unless I misunderstood that means in the "best" case, you pay roughly half the price per GH for something delivered >3 months later.
The network is currently more than doubling each month, three months could mean 8x lower revenue per GH. Sure that will stop at some point, but not likely in February.
"if you are in a hole, dig deeper."
Also note their ToS. For instance, for batch 2:
Batch 2. All of the 550 Baby Jet units from Hashfast’s second production batch are guaranteed for delivery by February 28, 2014
So if they only ship it by february 28, MPP adds at least 3 months, you would get your extra mining gear no sooner than June 2014 to compensate for your "november" order.

I guess the next important question is: when?
Will they ship immediately after the 3 month period, or at some time in the future?
