Looks like S4 is going EOL. Black friday deal posted on Saturday.
See bitmain sales announcement at the head (first post): 16 antminer S4 for ~13K with free shipping or ~$812 for 2Th.
Great price, but I have no use for 16 machines...
One machine is still ~$960 to US (with coupon that is expiring early tomorrow).
Exactly, coupon expires tomorrow, then free shipping on Dec 2. Marketing at it's best. |

No black friday deals, bitmain?
spondoolies is offering some amazing cyber monday deals. Naturally all before new tech is announced shortly. Those amazing deals aren't that much better - if at all - than an S4 with a coupon. Am I missing something here? Power usage is a rather large factor. Underclocking to prolong profitability. Check their thread and search for reviews not by Dogie since he's a paid employee these days. More evidence ... check sales of bitmain gear on ebay. I was in favor of bitmain till they came up short on price when you include shipping per GH and power per GH. Resale value is a short curve also. I think you're reaching here. I own a ton of Bitmain and Spondoolies gear. From S1 and SP10 to S4 and SP20. SP31 coming soon too. I like the wide range of Bitmain stuff, I like the tough rack-mounted Spond boxes. I don't see a significant difference in anything that you mentioned. I just sold an old S1 for $65 to someone in Montana, probably going to use for heat over the winter. S4 undervolts just fine. The point is, both are solid manufacturers, both made some boo-boos (S4 first batch, SP30 specs), both seem to be able to support their customers. No need to disparage one at the expense of the other. If you want to look at shipping and specs, SP20 is $815 shipped to the US for 1.7 TH/s and ~1150W, needs a power supply. S4 is $960 shipped to the US for 2.0 TH/s and ~1400W, no extra cost. Very close as far as I can see, and it makes sense - I bet both of these manufacturers are watching each other's pricing. Long live competition. How far can you underclock the s4? As for Dogie, he is a paid shill. Best to ignore trolls like him and stick to the facts. |

spondoolies is offering some amazing cyber monday deals. Naturally all before new tech is announced shortly. What new tech are you speaking of ? Are you trying to pump interest into sub 28nm tech ? or are you talking about repackaged 28nm chips ? I would like to see REAL proof that something sub 28nm is even at the foundry yet . I'm going to warn people about jumping on pre-order pumping anything sub 28nm .. If you look at the track record of pre order stuff it NEVER ends well … Even when it does make it to market it is often so late that you will never dig yourself out of the hole for putting up SOOOOO much money upfront for late delivers in hopes to get a jump on the difficulty increase … Because most chip producers are now heavily invested in their own cloud solutions by the time you get your product you will be getting the table scraps of any possible profit from the new tech … I'm all for mining but VERY anti cloud, and anti pre orders . 100% agree with NOT pre-ordering anything! The announcements for the new tech have been leaked by competitors (trustworthy) for the past couple of months. The tape-outs for first batch started this month. Assembly etc, next month into Jan. Announcements will therefore follow shortly. However, I will say, the SP20's ability to be turned down to 0.6J/GH at the wall, down to as low as 0.5 for some with no physical modifications make it a longer lasting product at this stage that we find ourselves as at with the current tech. Personally I believe bitmain made mistakes with developing the U3 and the C1. Waste of time and resources. |

s3+ upgrade path, to s5 with BM1384 chip 800gh at 0.5w/gh Should be interesting, whatever it is. The 15th has come and gone with no announcements. Another thread quoted mid december for first batch. Apple slowed down the tape out. So spon and a few others, will all ship in quantities feb through mar. Apr second gen around 0.2w/gh with as we all know, most bugs ironed out. Mid December for ordering falls in well, the S3 family will be at the end of their, "Return over Power" stage, by the time delivery gets under way. Watch for the next large PH spike which is due any week now. That will be your key as to someone "burning in" a first batch. By burning in I mean selling to one of the major players. I think this is starting to happen right now, but it is too early to say if it is Sp-20 from Spond or "something new" from Bitmain. We are currently at 310 PH vs 260PH yesterday. 50Ph is ~30000 Sp-20. I don't think that they have capability for such volumes, so my guess it is either KnC/Bitfury deployment or S5 from Bitmain getting burned in. Accidentally (or not!), last coupon for Bitmain expires on Nov 30 and next day, Dec 1, is Cyber Monday. Would be a perfect time to introduce something major... spondoolies already have their cyber monday sales up! |

Of course in the ideal world Dogie should be 100% independent from companies money. But we are living in real word where everybody need money. We don't have any proof that Dogie's rating became dependent. We just may believe or not.
Nobody knows who paid Dogie, I read just (from Dogie) about Avalon and Bitmain. After his announced both of these companies lost rating's points. It's fact and we should consider it.
Regarding ethics - I think lie and cheat are much much much more seriously than self mining. If we will count the number of negative comments per user in KNC and Cointerra threads, we'll not have any questions about ratings of these companies.
Why owners of Mercedes factory can't use Mercedes as a car?
So I can't be sure, but I hope and believe that Dogie's rating independent.
It can't be independent when Dogie is paid by companies on his list. Truly independent is off list. Worse still, he has links that he earns commission from. So the more he publishes, the more he gets paid. Click bait. |

I'll pick out the bits which actually have content in to respond. I'd prefer we did this in one of my threads in the future as its OT here, but I have to refute your claims. for instance, you STILL to this day, maintain that bitfury has 'ethics score of F = 8 points' because they have a small mine (really!!!!?  ). Had you not been biassed (or is it just blind?) the real score would've been 'FF, because they have the largest private mine in existence, dwarfing everyone else's... and a score of FF would've scored them -4 instead of 8 according to your own ratings FF was removed from everyone, its no longer used. KNCMiner had the original FF because they specifically said they wouldn't mine against customers in a large fashion, then absolutely demolished that promise. manipulated the numbers to have the ratings come out how you want
Manipulated the numbers positively and negatively against two companies I have no relation with - hmmm. And those 2 point 'manipulations' on a 100 point system, damn I'm a bad boy today.  By contrast, KnCMiner, you have scored as ethics F O , which is a huge private mine (-4 points). Does it even matter to you that KnCMiner's mine is significantly smaller than BitFury's yet your scoring system has it the other way around?
This is just pure bias and emotion - ignoring the facts. its a terrible ratings system, Dogie, because its only You and there's no objectivity in it at all.
The evidence you've provided is irrefutable, you got me. But in all seriousness, you've said nothing that suggests I've manipulated the ratings or I have any personal or emotional attachment to the two companies you've stated. On the other foot, your post history suggests you are extremely supportive of Cointerra, and are annoyed that they have a low (rightful) rating. Dogie you can't run a serious rating system when you are connected to companies in said list. Grow up! |

you'd have the following costs for electricity:...
if it's done right, cloud could be a great thing. However, it needs 100% usability, and that doesn't come cheap, it's a lot of work... where one miner may wish to mine with hardware themselves and pay electricity at home/location, another may wish to mine on a cloud and pay the maintenance which is inevitably going to come with that - but either way, you still fund the electric costs, do you not? Here's some quotes from Guy: Home mining is not going to be around much longer though. The big mining farms are making it so you cannot compete or get ROI. Whether we like it or not mining is moving to the cloud. There will still be some home miners, but not many and most will be in the cloud. We believe that 2015 will be all about mining contracts. Mining contracts backed up by real hardware. I agree with Guy. the only advantage I see of cloud mining is that anyone can have as much hash-power as their funds can afford without the worry about keeping within the limited power draw for their mining place. Just because you are mining on a cloud contract, does in no way negate the electricity costs. I'm content to mine at home/data-unit and stay within my limitations. Also, home mining in winter helps reduce your home heating bill. That's an added benefit if you are going to pay for that heating energy anyway. Cloud mining won't be around for much longer. If it was purely profitable they wouldn't be trying to get extra profit by on-selling the product. Cloud mining is just another way for those companies to make more profit. If it costs you too much to mine due to power, have it hosted somewhere cheap you can trust. As pointed out also, heating costs can be greatly offset with home mining. |

new products due to be released shortly by bitmain and it's immediate competition. At which point they will announce pre-orders for delivery likely early next year.

I know this question has been asked before a long time ago, but I can't find it anymore...
Is there a way to automatically let an AntMiner S3 reboot every eg 24 hours?
Thank you!
This will greatly reduce the life of any electronic item. A large temperature jump (more than 5c per hour) will half the life expectancy of a chip each time. Whilst they may last decades... well you get the idea. However, since these units are only designed to last 6 to 12 months, go for it! |

Anyone have a link to a decent and relatively cheap solar panel distributor?
http://sunelec.com/Great prices for the U.S and even better prices outside of the U.S. Long story but this was one crappy decision by Obama that screwed over the international solar industry. |

there is no oficial bm1384 yet
bm1382 is on 28nm
next chip, maybe called bm1384 should be lower
22nm? 14nm?
BM1382 isn't a very efficient 28nm chip. If they do come out with a new chip so quickly, it'll probably just be a more optimized 28nm version. Tick Tock. It may be overclocked like the S1's were, leaving some headroom to lower it in a later model to compete with others. |

Price for antminers has reduced  S4 is $1200 per unit S3+ is $199 per unit C1 including cooling kit is $375 per unit and $325 excluding cooling kit Shipping for 4 S3's to the US is nearly $200. There has to be a way to get better shipping rates. For air freight, 2 days typical is comparable to all the other suppliers. By boat (6 to 8 weeks) you can get it cheaper. |
