Hey Mr Lee, with SHA256 miners dropping in price drastically (Bitmain S3 now sub $1k/TH) do you think the factory are due any price drops soon?
I have had my dragon for about 70 days. but this price change by bitmaintech will change prices. remember it does not ship for 10 days or so. Of course, but then you can't buy hosted miners from here till aprox the 8th either. BTW This isn't a dig at Mr Lee, I know his prices are based closely on what the charge at the factory is, I was just trying to find out if he knew whether the factory were going to drop their prices in view of the competition. I hope so. if the S3 are as stable as S1 and the price is 0.75 as they set, i think the factory of dragon will drop the price to be competitive, Any news on the 1.2TH 1.5TH and 2TH options they have had "coming soon" for a long time? Either being scrapped and remodeled to compete or won't happen, most likely. Oh I dunno, there is a lot of profit in these for the factory. If they can sell them cheaper than $1K/TH but maintain around 1W/GH then they will sell. I know there is  That's why I led with being remodeled (physically, or financially) to adapt. The hardware is there, they just have to make it efficient and make sense on paper.  Prices are coming down all over the place, the 34MH/s B2 is now $1700 shipped. It must be hard to keep up with the fast moving pace as a retailer. Yep, a lot of it seems to be the wait and see approach and adjust to the market. yep since gear is more abundant then ever. buyers have some choice. I no longer buy in bulk. I buy a few pieces at a time to protect against dropping prices. |

Thanks for putting this together. I'm confident that J/gh will decrease enough to mitigate this, but the possibility that all mining hardware producers fail at making a more efficient miner is highly improbable (especially because there are so many now) but not impossible!
I am curious about your statement. How much more room do you think there is in this number? At 28nm everyone is getting about 0.8 J/GH. Going from 55nm to 28nm only reduced the consumption from 0.9 J/GH to 0.8 J/GH. Lets say we can make 18nm chips. The best case I would see is 0.5 J/GH and it would probably be higher. In other words I don't see any way to get another order of magnitude change in this number - only smaller incremental improvements at this point. Running the numbers at 0.5 J/GH is not a whole lot different than 0.8 J/GH and 0.5 J/GH may be a total pipe dream. so lets say in 6 months the network drops to .5 J/GH and the that is close to the brick wall. what would you predict price on JAN.1 2015 ? Since I used 1 J/GH you just divide all the posted energy and cost numbers by 2 if you want to assume 0.5 J/GH. So about $1,174.66 per BTC. Thanks for the info. For the sake of argument lets say .5J /GH and If coins halved to 12.5 per block on Jan 1 2015 (I know they do not) you would use $2,549.32 correct? |

Well the bubble is exploding! GHS price down to 0.006 and dropping fast!
pop pop pop I purchased a bit today at .0060 put it back for sale at .0065 I put in a second order at .0055 And in under ten minutes it bounced to .0065 and i made some btc maybe someone playing with it? internal person maybe i'll try your method, maybe i can make some profit there  it is a guessing game at best. I check the site every 4 hours..Then if I stumble on it with a big drop like today I buy some and list it back about 7 % higher. I turned 50 ghs at .0060 into 50 at.0065 in under 10 minutes , but that is truly due to looking at it in the middle of a good drop. if I had checked 10 minutes later it would have been at .0065 not .0060. |

Did I read correctly that it only needs 2 PCI-e cables connected to run as normal (not overclocked)?
Correct. 2 for regular, 4 for OC'ing. What I do not understand is this sentence: "Don’t parallel connected different DC input from different PSU into the same Hashing board." So does this mean you need two PSU if you're overclocking? I understand they mean dont use 2 PSU for same hashing board. Anyways, with 1 PSU u can connect 4 PCI-e so no problem yeah this is most likely exactly what they mean. but with 2 psu's each one doing one board each even thou it seems okay I will let some one else do it first. |

So does this mean you need two PSU if you're overclocking? I would think the opposite just use 1 psu with 4 pcie cords not 2 psu each with 2 cords. best to be careful let some one else be the first tester of that |

Another cool use for the breakout boards: I'm using the 5v to power the AM-V1 RPi controller and control the PSU. Just strip the usb power cord(included) and slot the red(5v+) and black(ground) plug into the 5v connectors on the breakout board. Now you can power your BTCGarden AM-V1 and RBox units off of the same PSU.
I also want to note that you do not need to purchase an RPI controller from me. If you have your own, I'll can send just the SD card and RPi data cable.
the break out boards with mstrongbows protective case. can power: 1) r-boxes 2) rasp pi 3) gridseed blades 4) usb hubs 5) five chip gridseeds Right now I run 2 gridseed blades with mine. I plan to run 4 blades with it. I also like my r-boxes your build has proven very stable. 3 pull 115 watts for 97 gh at current price of 650 a coin they are pretty good gear. I think they also provide 3.3 volt for something.. but be very careful on the 5v, its not designed for very much load at all. thanks it is good to know. |

Thanks , but I went to the link and the price is 3296 for 8 plus shipping must pay in btc. the price is 866 for 2 plus shipping must pay in btc. on zoomhash I paid 889 for 2 with shipping included used paypal and I will get 2% back in a promo from paypal. so my net was 872 including shipping with paypal's safety net I get 45 day protection for doa. So for my purchasing level zoomhash is still the winner. Both price and safety wise. I know it seems like a commercial for them but it is simple facts no extra back door deals. here is a shot of the miners on wemineltc. and I have tracking for my 9th and 10th ones.  |

most likely it would. it has ohms at 20000. the 8 stock resistors should read 4470 so if you set the ohm part of the meter to 20000 you should get 8 readings close to the same. if you do the 2-3 pencil strokes it should drop to 3000 as long as the 8 resistors are all close it is the only reading you need. mine range from 2.9 to 3.4 k or 2900 to 3400. i allowed for that much variation on purpose so that I could post on this site that perfect ohm readings of 3200 or 3.2 across the board are not needed to work. |

Bitcoinwisdom that you linked yourself is still estimating +15%. Don't be fooled by day to day variance.
true right now it is a lot of guess work….. using times between blocks days in advance is meh. besides a builder like bitmaintech could have 200,000 s-3's built and ready to ship right now. So while it looks like diff jumps may be low it is more because they hold back the gear. |

Silver fish is a good price. but I keep getting the gridseed blades. I just purchased 2 more from zoomhash.
with coupons 2 for 890 usd .
if you use a platinum psu they use under 90 watts for 5mh.
if you swap the fan for a noctua 92 mm they run cool and they are quiet.
at 445 a gridseed I am happy. once these come I get some more.
did you see someone has them for $399 each now? no I did not and it is good too know as zoom hash offers price match. please give link and I will ask mike of zoomhash to match it. |

Has anyone else had intermittent problems accessing the big stats page on the website over the last 5-7 hours?
yes it pops up as all blank. but I still have been mining |

I purchased 2 s-3's from them yesterday. BTW they dropped to .74btc for the next batch. I purchased 10 gridseed blades from zoomhash. Right now I will mine and wait to see new prices. |

Looks like BTC may be in for a little upward trend. I do hope we do get 100gh per share. These minion chips are quite good so I`ve heard so high hopes for these.
well it would be funny if we get the 100gh and coins go back to 900-1.1k. we would actually turn a usd/fiat profit There is absolutely nothing about this group buy could ever be regarded as 'funny'! With minersource refusing refunds (we bought from minersource not BA) 4 months after failing to deliver, and the DZ guys going AWOL/turning native, Bobsag3 could yet find himself in court! There is certainly a good size cadre of people who seem to want to follow that path. Hey I will lose 630 usd and the part refunded was done at a 200 dollar loss. that is 830 usd lost plus the money lost on round 1 about 1.55 btc but 200 usd. so my losses would total close to 1030 = not funny but if they gave us 100gh a shares and coins went to 1k I get a usd profit = funny . I had 530 usd refund from bfl 13.5 months after the fact = funny as in I would have bet my left nut that it was a complete loss. If I get this money back from this deal I would be laughing. As I would bet my right nut that it is not going to happen. BTW I like Bob, zombei and tom. I actually made some money on other deals with them. But business is business and if they get sued over this I certainly would sign on in the hopes of getting some more money back. |

Enjoy losing your money guys, that's what will happen  +1 no problem, they are ensuring the network Funny (or sad) thing is that professional investors who run gigantic farms will soon be out of business ... even at $0.05/kWh. Lesson: Never underestimate the stupidity of the masses Well who's stupid? Miners ,builders , investors all of them? Like it or not it grows by it the cyber coin universe is expanding as I type. Do you know what would kill it off. Raise interest rates to 5-7 percent. Bring back 30yr US Bonds at 9%. = Death to this universe. Here is the deal people with a little bit of extra money or a lot of extra money need places to invest it. Buying cyber coins is like buying stocks . Passive investing. Mining is more like running a business active. Does it really do anything does it have a purpose? Yes it offers a chance to make some money if you work at it and it is your own business so to speak. One you can do in house. |

Washington-based MegaBigPower (MBP) is North America’s largest mining operation. The mine, which generates millions of dollars worth of bitcoin per month, began developing its franchisee network earlier this year. Now, the company is planning a broad expansion effort that could add as much as 50 PH/s in mining power per month to the network.
50PHs per month ? Doesn't look very feasible. +1 MegaBigPower is noted for over blown statements and since no chip was announced to support 50PH a month. Maybe everyone already has a cell phone so the foundries are looking for work.. 50 ph of hash = 10,000 sp30's at 2000 watts each = 20,000 k watts = a lot of heat big time heat 1 k watt is around 4000 btu's x 20,0000 . add in lots of ac. I would think it can't be done until you get to a .05 watt a gh chip. |

ok, now I am running profitability estimates using the Antminer s-3 numbers and my local power costs. Very interesting, it seems the concept comes down to converting electricity into Bitcoin. The following parameter has me confused:
---
Difficulty override
The estimated difficulty change from BlockExplorer is used by default. Enter a percent value here if you want use a different one.
---
Their default is -6.1% change in difficulty but from what I hear difficulty goes up not down. On the TradeBlock chart difficulty recently jumped rather largely. I replaced the -6% with a +5 and can see that the prediction is for declining profitability. +10% is definitely trouble. I will keep on reading but are these estimators accurate? What % makes sense to plug in?
diff jumps calc at 8% 10% 12% 15% 18% 20% 25% at 25 no go at 8 yes. the real number  my guess is 14 to 18% right now buying to mine does not look as good as buying coins and holding. the mining game has a lot of factors. s-3 is a nice space heater in the winter. do you have noise tolerance? a place with some cheap power. etc. |
