Bitfury is half the power usage. Not to mention that is actual not theoretical. bitfury is 1000 dollars more for 400ghz minervs knc. Not sure if that is really blowing it out of the water.
Oh good, half the power usage, that should save me about a dollar a day, only 3 years to recover that from the power savings. Get real! |

It's not about rising difficulty, it's the question of, if the difficulty were 1 billion today, would the device earn money above its electricity costs. The answer is yes, about $17.50 a day:
Even that depends drastically on your electricity costs which vary from < $.08/kw to $.22/kw. In Europe, power is even more expensive. Obviously if you have free power, then that's a different story - once the purchase costs are paid for, then you never shut it off. It also depends drastically on the price of bitcoin  Long story short, a KNC miner has the best prospect of long-term mining profitability around, except for perhaps Bitfury whose chips are more efficient. (But for how long? Gen-2 KNC device will probably beat them on that metric). how are BitFury's more efficient? Bitfury's chip is more efficient in terms of gigahash per joule of energy. This is likely because they did a full custom ASIC. Maybe the actual device will be a bit closer together on efficiency due to one being solo chips and the other being VLSI, but Bitfury's chips is significantly more efficeint. It's not 1,000 watts though. That's a worse case scenario... It's probably gonna be like 750 watts. Bitfury is still winning that battle. Bitfury doesn't win the battle at all, it's about ROI of which power consumption is just one part. 1,000watts costs most people only a few dollars a day, trivial when you compare how much BTC the things produce. |

has anyone been able to find a XPM block with bfgminer?
Yes, on mainnet. But it was on a heavily modified bfgminer talking to a modified primecoind. The variance on solo mining is so large that I'm still not able to make an accurate determination on whether bfgminer is faster than running native primecoind - the speed at which I can mine on testnet certainly indicates that it is, but on mainnet it seems really slow (but maybe it is just the huge difficulty now) Will Anyone tried to mine with ypool.net instead of primecoind? |

I have tried yesterday, but with the primeminer 0.2.4 version I'm getting more rejected share than accepted. So I think is still lot to do.
Where is version 0.2.4? I thought it was 0.2.1? The jhprimeminer v0.21 keeps stopping for me on Windows 7, have to Ctrl-C and restart it often. Very unreliable. |

For those that do not have time to read the rest of the threads:
If KnCMiner hits their delivery targets, the existing competition will likely out produce and out price them before or soon after their first units are delivered. Multiply whatever hashrate they produce by an appropriate constant when you do your ROI calculations.
They may be a very competent technical team. However, KnCMiner has no power to "protect" your ROI. It doesn't really matter what their intentions are. The only way to protect your ROI would be to guarantee a percentage of the global hash rate for every purchase you make with them.
I doubt it will be that simple, KNCminer specs are way ahead of the current competition. The industry loves to tell the world about products that don't exist for months, giving KNCminer ample time to plan and react. At the time KnC hits the market there are tens (perhaps hundreds?) of Th/s from BitFury online. And it doesn't seem likely KnC will be anywhere near Bitfury's Gh/W ratings. So good luck protecting your customers, KnC  Have you looked at the Bitfury prices? They are not cheap, I was disappointed when I looked at the Bitfury prices. KNCminer blows them away for value, ASIC running costs are currently trival, so the GH/w is a small part of the equation atm. unless you are trying to set up a data center full of miners. |

I have been slowly mining NVC on port 3344 all day, most of the time over the past several hours it's showing zero hash rate yet cgminer is happily showing accepted shares, sometimes there are round share, then they are zero a little while later but a block hasn't been found for 120hrs, the per-block estimate was showing like 8.0 an hour ago, which was too high, and now zero, the pool hash rate is showing zero but that's not right. There is something not quite stable going on.

I haven't bought any BFL products, but I'd find it hard to believe they wouldn't take a picture of more than 18 units if they had 300/day shipping.... maybe they mean 300 chips per day are leaving the warehouse?  They are most certainly not shipping 300 singles per day, and they most have taken pictures of hundreds of jalapenos in production before. |

For me, this statement means different things (apart from good or bad PR/ intentions) -> They dont intend to further flood the market after diff. got to high for their 1st gen devices to ever ROI -> They want to protect customer ROI to let them reinvest in new gen. device (good for customer & good for them) -> Keep diff. low enough to farm with their own devices (good for them) -> Signaling other competitors that they do not want to get involved into a senseless, neverending, all ROI destroying ASIC race -> Signaling other competitors that they are interested in a slow growth of network diff. which would be the best for the whole network -> Signaling other competitors that they are fully armed in case it comes down to a race -> Signaling customers that their product is limited (-> buy it, now!, good PR move indeed) -> Most positive signal for me -> they are very confident about what they do ... place your bets  Probably several of those points at the same time. In less than two months time, they are going to start shipping thousands of units between 0.1 to 0.4TH/s, that will be a significant impact on the BTC net hash. The are not kidding when they say flood the market. Possible as much as 1,000TH/s worth working on say 5,000 units at .2TH/s each on average. |

Sounds like utter BS to me Which it probably is, but not any more than KnC's BS statement deserves. Anyone with basic arithmetic skills can work out for themselves that it's several thousand percent more profitable to sell a miner that takes an hour or less to build, than it is to use the same miner for weeks on end just to get ROI.
Anyone with basic sense of logical thinking can work out themselves, that KnC can use this statement to mine almost three months and then sell that hardware late "to protect their customers". Whatever the case, the statement is clever PR. And miss out on 3 months of production worth hundreds of times more in sales than the mining could ever provide. I think not, more likely they want to use the break to work on the next gen wafer run which would take about 3mths. They are making millions from this first batch, with which they can buy as much BTC as they need. |

so the PayPal stuff didn't work. I ended up paying via BTC. I tried making the url HTTPS but then some other web site showed up at your address. Not to mention that I had to add a security exception since the certificate didn't match. In case you are not interested in wasting a lot of money on HTTPS certificates - check this site for a free one: http://www.startssl.com/?app=40I had turned it on briefly for a customer to test but it didn't go well. Have turned it off again. I want to get it sorted out but for the mean time if not too many bombard me I can probably enter orders manually and send a PP invoice. Ya, this OpenBitcoinStore thing isn't working well for me. It doesn't have SSL support, and as you saw it seems the shared IP is going to cause issues with site conflicts. So I'm going to have to move everything to my own server for SSL to work. Could also be related to why paypal doesn't work - maybe it needs to talk to an SSL page to hand off the details etc. They claimed it was a one-click deploy but it's been kind of useless as I've spent considerable hours trying to get things arranged and functioning in a way that ANY web store would need. I should have just started on my own server to begin with but I thought this sounded like a quick way to get it up for people. No such luck. Anyway, thanks everyone for the patience. It'll get worked out. (SSL certs no problem - have used StartSSL before and done all this before manually via SSH - oh, when point and click is harder than bash!) Only one SSL site per IP, for each additional site you need a separate IP. |

How long to receive the coin in P2Pool?
receiving should be within minutes, however it may take a day before you are entitled to receive a coin, you have to earn p2pool shares first, then the pool has to actually find a block. I wouldn't recommend p2pool if you are not familiar with how it works, you are liable to receive nothing if you don't do it correctly. eg. you must use your own wallet not Cryptsy. |

Hm, LTC is down, which is pretty critical.
May I suggest that you continue sending the stale data (at least in JSON), but add a new field, which flags the data as stale?
LTC is working for me, shares accepted, just the website being silly on a number of coins. |

Same here, all scrypt mining seems to be down. All ftc shares rejected.
Trc is still chugging along though
ARG and LTC working, NVC isn't. There was some sort of an attack apparently on FTC about 12hours ago, but that's well over and done with I believe, though it's hard to get info out of those guys, the want to do PR damage control more than discuss what's actually happening. FTC is currently disabled on Cryptsy. |

What I don't understand is the incessant talk of scams and stunts, as evidence accumulates pointing otherwise. The BFL delays severely impaired the value of the shipped units, no doubt about that.
When people smear something, it's usually because they have a vested interesting in something that it is competing with, so you just have to work out what that is. |

Avalon recommend that you order the unit without the PSU and get one locally exactly for the customs reason.
As I recall, this was not an option for batch 2, but only for batch 3. Doesn't matter if it was an option then, now it's his only option or a refund. |

Hey! Everyone the Klondike Store is open for orders!
Are you going to eventually sell complete boards ready to go with ASICs as well? |
|
|

I'm guessing my little Jalapeno in a few months may become obsolete for mining bitcoins much like my graphics card has. So is there life after mining for these units? For example, can you use them to hack passwords, etc? Just curious if there are other uses than just mining.
ASIC stands for Application Specific Integrated Circuit. Think about that for a minute or two. |

Would it be feasible to remove BFL ASIC chips from BFL units and put them on your boards? Your board design may end up being more desirable than BFL's, especially for the clock/voltage control.
Without special reworking equipment, you would most likely destroy them. |
