Hello,
I just ordered a full kit yesturday (Order #1180) and the bank transfert had just been confirmed today. Anyone could give me an idea of how long it will take to be delivered in Paris, France (knowing that i also paid for the express delivery option)?
Thx!
We don't currently sell full kits. We sell H-cards and M-boards. Your hashrate may vary. Each card has been tested to deliver 25GH individually. Full rigs will be made available later, but will be priced higher due to the extra time it takes to set them up for the advertised hashrate. punin, do you think new h-boards will have a substantially lower price ? spiccioli |

Nice growth lately, we're around 30 TH/s now. spiccioli edit: and five blocks so far... we should try not to get accustomed to such a bonanza...  Maybe we have broken numbers and they don't work correctly anymore. Keep them as broken as you can, fireduck!  Last block paid a good .25 BTC to its finder! spiccioli |

design boards that fit in standard avalon casing! so we can scrap the old cards and get 4x80x1.5GH per unit.
+1 there are around 1500 Avalon units from batch #1,#2 and #3 Create a blade which can be used to replace a current one in an avalon and sell it at a price which leaves a 20-30% earning margin to the buyer and you can probably sell six thousands of such blades in a few hours... spiccioli |

All you have to do is configure BFGMiner for failover to solo-mining like: bfgminer [...put your real GBT-based pools first...] -o http://localhost:8332#allblocks -u username -p password This will make your miner also submit any blocks you find to your local bitcoin node, which will undermine any attempt to delay the announcement. It should also help your pool get a lower orphan rate, since it'll start the exponential spread of the block one round-trip-time earlier. Nice, but you have to have a bitcoind running somewhere, which most of the miners don't have or they would already be going the p2pool route... An even easier solution is to stop being a lemming and start mining on a smaller pool, it does not really matter which one, just avoid mining on the PH one... spiccioli |

Full August kit, paid around 310 BTCs, up to now has earned around 114 BTCs, it will NEVER break-even.
spiccioli
Yes and in August BTC was ~ 100$ Now 242$... I have a pretty smart tip for you : In futur just buy BTC because 1 BTC today is still 1 BTC in 1 month or 1 year. The best ROI, break even ever ! No loss Sure fractal02, I've learned my lesson, but it seems a lot of people did not (yet) and keep buying overpriced hardware instead of BTCs, this is what we're talking about. spiccioli |

That ASIC earned itself in ~2-3 months, try to find some similar return of investment in other business segments. Miner's falllacy. In fiat terms you were better off buying bitcoins and/or not spending them to get hardware. And today you're better off buying BTCs instead of overpriced cards. Right now ASICs keep selling because people keep thinking about fiat currency... but if you believe that BTC is here to stay, you want to have BTCs not USD/EURs. spiccioli |

Do you get that Jupiter shipping tomorrow?
No, but it does not make any difference, they won't break-even even if both were shipped tomorrow, at least with a KnC: - you lose less - you don't risk having several boards underperforming but barely reaching 25 GH/s and as such considered good - you don't have an 18 pieces jigsaw which performs differently based on the order in which you assemble it, room's temperature or moon's phase. I bought a full october kit, at around 110 BTCs more or less, and it has up to now mined 14 BTCs and I've received four EOL boards which don't even reach 25 GH/s and one of them had to be moved to a different m-board, otherwise it was slowing down/blocking three other cards. I mean, at least october kits HAD to be made by good cards ONLY and more so for customers that already bought august kits (by miners for miners... yeah, right!) Instead they recycled old, underperforming, august EOL cards. spiccioli ps. I'm not angry with punin, he has done a very good work shipping units mostly on time and has good customer support, but prices are made (by bitfury?) so that it is assured that you can't break-even, even if other players are late or don't deliver. I was well aware that it was a gamble when I ordered my units and I'm aware that I've lost this gamble and that in life sometimes you win but most of the times you lose, but at least, please, don't try to tell me that they're better than other sellers (apart from BFL which should all be in jail). |

H boards are out of stock, wow.
Nice! less people will loose money on them spiccioli with starter kits paid over 1000 $, I guess that a lot of people already did loose and is just trying to recoup something. Adding a non breaking-even board ontop of a non breaking-even kit... I don't understand how you could be better off. spiccioli ps. if you don't pay VAT you're better off... a little better off. |

I already had positive ROI on my August starter kit. No idea why you guys would have a problem. Full August kit, paid around 310 BTCs, up to now has earned around 114 BTCs, it will NEVER break-even. spiccioli |

Guys,
there are only two kind of pools:
- too big
- all the other pools.
Choose wisely, choose a smaller one and in doing so:
1) - help increasing bitcoin network health: DE-CEN-TRA-LI-ZED means nothing to you?
2) - be a bigger fish in a smaller pool (instead of the other way around), remember: bigger fishes eat smaller ones.
3) - please do understand that all the hardware which was bought in the last four months and all hardware being bought from now on is NOT going to break even, so pool choice makes no real difference FOR YOU but can make a difference for bitcoin network health, see point 1)
4) - a better bitcoin network health can help increase bitcoin value and in doing so can help you earning more from your investment.
Variance means that some days you get less, but some other days you get more and the days when you earn less are LONGER than the days when you earn more, so be patient!
A smaller pool is easier to monitor, a smaller pool has to have smaller fees, a smaller pool is more enjoyable to join since you become part of a (smaller) community of miners which share your same goals.
Stop being a lemming, start mining somewhere else!

wow add VAT and see how much you get out..... overpriced for me, I was expecting cheaper hardware after the successful run they had and the positive experience.
A KnC Jupiter is definitely cheaper now at 4995 USD instead of 5700-5750 USD for a full rig made up of 16 h-boards + 1 m-board + 1 raspPi. And h-boards are "certified" at 25GH/s, so you could end up with a 400-450 GH/s bitfury unit instead of a 500-550 GH Jupiter if you're unlucky and get underperforming cards. spiccioli ps. the whole bitfury's idea was a lot of "small" chips against a few big ones... but if small ones are priced like this, the whole idea does not work so well. |

H-Cards in the shop :-)
With lowered price. Interesting to see what price will be in January  Now is more resonable to buy H-Card and desolder chips if you want chips cheaper Hmm lets count. Chip in reel cost 15eur Chip from H-Board 15,63eur boards are not free... spiccioli ps. plus VAT |

To answer some PM questions
- I don't have physical access to the miners, anotherhost is a secure facility with government and law enforcement clients. No unauthorized entry, no photographs, etc
- I have never seen any of the units, I have no idea which production line stickers they have. They were all day1 so most likely have 8 VMUs as they were delivered before the manufacturing change
Nice, now let's start talking about a fair price... spiccioli |

Nice november start, eh?

Btw, last block had 0.25 transaction fees in it, so who found it got a nice 0.125 BTC prize spiccioli |

hopefully the price will be set <2BTC at this point
+1000. At least for returning customers, I would buy a bunch then.. August customers should (deserve to?) get a special price... punin what do you think? spiccioli |

I like the approach taken but the scale is simply unrealistic. For the sake of the argument lets assume the chips (silicon & packaging) is possible at $0.20 per GH/s ($20 per TH). Small runs (less than 1,000 wafers) at 28nm are probably more expensive than you think but lets ignore that and look at the rest of the system.
For example lets try to guesstimate the balance of the system (everything but the ASIC) on a Sierra. Here is my guess what is yours?
case: $60 * 1 = $60
watercooling: $80 * 3 = $240
case fans: $10 * 2 = $20
power supplies: $150 * 2 = $300
PCB (both PCB manufacturing and assembly): $30 x 3 = $90
DC regulators (12V to ~0.8V 200A output ea, 2 per board): $30 x 6 = $180 (probably more KNC uses >$300 per 400 GH/s system)
minor components (connectors, capacitors, etc guesstimate 100+ components per board): $50 x 3 = $150
labor (post PCB assembly, testing, packaging): $50
Balance of system (excluding ASICs) = $1,090 or $908 per TH/s.
That is nothing for fixed costs, markup/profit, yield issues, customer support, shipping losses, warranty, etc.
Now say you could cut that in half and had free raw chips that is still >$5,00 per TH/s. Maybe with enough volume and streamlining you get the cost down to $250 (and assume no yield losses, customer support, profit, etc). Personnally I doubt it but maybe. However your charts starts at $250 and go to just silly numbers like $50 per TH/s. That would be $60 per Sierra equivalent (or $25 per KNC Jupiter). Say I gave you 1.2 TH/s (or 0.5 TH/s) of free chips show me how the balance of the system would only be $60 or $25. Pay close attention to DC regulator (VRM) costs and power supplies they are more expensive on a $/GH basis than you might think.
The power axis is misleading because power in = heat out and then it takes more power to remove the heat. So even an generous (I would say unrealistic) 8 cent per kWh, 20% cooling overhead (PUE 1.2), no real estate overhead, and $500 per TH is more like "end game" of <225 PH/s at current exchange rate. Kinda shows how silly projections of >650 PH/s in less than a year.
i recently did my own guesstimates of the cost and came to very similar conclusions, though i think you're on the low side for the actual asic costs, but i think you've overestimated the power supply and cooling costs, as they appear to be using relatively off the shelf parts, which will be in volume production and they're not paying retail prices for them. I think this is very critical, because what it shows is what I've always been saying, that the cost of the system is mostly "other stuff" (psus, cooling, case, pcbs, fans) and not the actual cost of the asics, thus you get enormous cost/performance improvements by having faster asics, as the rest of the system doesn't change in cost at all if the asics went faster! And to reduce the cost of that "other stuff" bitfury did try to build minimalistic PCBs, but so far has had some problems... https://bitcointalk.org/index.php?topic=251966.msg3425695#msg3425695spiccioli |

p2pool.info is best at any time because of it nature!
- 0% fee
- PPLNS
- tx fee for miners
- decentralised (ddos impossible)
HHTT is on a par on a lot of things and easier to setup:- 0.5% fee (p2pool has a default 1% fee to its author which you have to disable if you want to be 0% fees) - PPLNS - 1/2 transaction fees for the miner who solves a block - high availability and resiliency (I won't say it cannot be DDOSed... but a lot of p2pool nodes could be easily). spiccioli |
