Will you offer hosting?
Where are you located? general a state or if not US what country not an exact address.
If you how what will you charge?
If you mine just for yourself what machines?
They have a website: asicspace.com price $80-95/kw/month with more undisclosed discount for >30kw customers. Not as a criticism, but I don't get it why all WA hosting has the same price: roughly $85-100/kw/mo when their cost in electricity (2c/kwh) is just 16-20% of cost of electricity in US on average (12c/kwh). Their electricity cost is just $15-20/kw/mo vs $88 average in US. Do they have some kind of a union there that prevents going lower? It's the same reason you want your miner to be making more than it costs in electricity: you need that margin to cover the initial capital expense. In your case, it's the miner, in our case, it's an expensive data center meeting the needs of a speculative market. Also, hosting in WA less than a year ago cost $200/kw/mo, then Hashplex came along and offered $100. I'm sure it's still headed downwards. Fair enough. |

why do some s3s work harder then others? so on my pool it states how big of shares peoples workers submit and when they hit a block. on my s3s the biggest shares are usually around 30 billion and most of the times its under 10 billion.. sometimes its even in the 100s of thousands  on my pool tho, it seems there are workers that often always hit the shares in the trillions.. there are also workers that get 2 or 3 blocks a month.. while mine have never even gotten close.. is there a trick? like assigning the same worker to more then one s3? currently my s3s all have their own worker on the pool. i know that some workers arent all s3s, but i know most are. Why is this relevant? If you are mining in a pool everything gets shared. Even if your miner hits a block, the block would not be given to you. This is the flop side of pool mining. If you want to mine a block with a reasonable expectation -have enough hashing power and mine solo. Still, variance can ruin your day. |

Why mining can be sweet when the price is right:
My six antminer S3 at home produce roughly 1BTC/mo right now, but use just $180 in electricity (after heating savings).
The bottom line is that I am basically purchasing BTC at less than half the price plus they already produced more than I bought them for initially.
Looking forward to S5.
Yep me 2. If you don't mind me asking, who do you mine with? you mean pool? I usually rotate among the usual suspects with the exception of ghash. |

I heard a RUMOR from a friend of a friend who knows Zuckerberg personally that the Facebook guru is planning to pump $100million into Bitcoin
True or not, I don't know - but my friend is hardly a flake. I wonder what a Zuckerberg entry into the Bitcoin market would do to the price?
maybe. Zuck's logic: 1. If I invest 100 mil right now, I will have ~0.26 mil BTC [likely less because it would appreciate during buying of such quantities] 2. 0.26 mil is MUCH more than Winkelevoss twins have  [they have ~0.13 mil BTC] 3. Hence, I win, AGAIN! [100 mil is just ~0.3% of his fortune-good for diversification anyway] |

Fantastic work.
Is this a go for S3 or just S3+

Great for you guys . A somewhat sore note: I observe a current lack of real bid on mining gear on ebay and that includes Bitmain S4 (bid below market for new), Spond Sp30 (no bid) and SP20 (bid below market). Either the market is saturated OR people save money for holidays. Stagnating BTC price is probably another cause. |

Will pay 1.8BTC for S4-batch2

I looked at the numbers and either bitcoin price has to increase to $600 or difficulty has to go down 20-30% for current NEW miners to make sense economically. I wish Spond would position SP20 as a 1.5 TH miner at 1000W for $600, but they know their bill of goods and I don't , so this may be impossible. BTW, Guy Corem thinks that current miners (0.5-0.7w/Gh) are all becoming uneconomical in the near term. https://www.coindesk.com/bitcoin-price-decline-sparks-rare-mining-difficulty-drop/Guy Corem, CEO of ASIC-designer Spondoolies-Tech explained:
"Under the current bitcoin value, mining gear efficiency of 0.5–0.7 J/GH range and energy cost, we'll reach equilibrium very soon."
In layman's terms, with bitcoin prices in the sub-$400 range, mining at a difficulty level of 40,000,000,000-plus simply does not make economic sense with current-generation hardware. |

http://coinde.sk/1wiIEAGinteresting. and perhaps a tad sycophantic so feel free to shoot me down in flames, but this is what i believe. my reasoning is that for the first time, ever, we have been dealing with a company who have not only turned out the most efficient hardware from their own IP but have also flown in the face of all other h/w manufacturers by striving to assure 100% customer satisfaction. in this industry, it's unheard of. I just want to say, if you don't win this Guy, well done for rounding up such a skilled team, and for everything that you do to service our mining requirements. Although you are obviously driven by the profit which keeps you in production, so are we and I wish to applaud you, not only in that excellent customer service, but also in the actual hardware you have produced. <insert standing ovation here> >snip<Mining is not important in the great scheme of things. We could still be using GPU miners and bitcoin would be secure enough. I beg to differ re mining. Mining has been the most exiting race I was a part of in a small way. Comparing to the sluggish software development, mining advances were on the forefront of bitcoin, no doubt. If i compare my wallet circa Dec 2103 and todays-basically NO DIFFERENCE. Please don't tell me about multisig and the fact that I can store $$ on coinbase IF I reside in 13 lucky US states (I am not). The argument re GPU is disagreeable if you consider FUTURE bitcoin use and transaction volume. |

I wonder who swithched OFF ~30ph in basically one day. It plunged from 304 to 274PH.
Network was kind of weird in the last month or so-sudden surges followed by deep plunges in hashing speed.
I still stay by my conviction that it would pay for someone to purchase calls on bitcoin, then purchase hashing, switch it off and see a spike in bitcoin price soon afterwards. Rinse and repeat.

I have a new one I can sell you. I want around 1100 for it.
Price for used has to be below $930. You could buy new for $930 with delivery to US (with coupon that everybody has a gazilion of). |

I would like to buy antminer S4 of the 2nd batch (not early 2nd batch that also had many failed PSU).
PM or post if you have one for sale.
Seller has to be in US to minimize shipping charges.
I will pay for escrow-either ognasty or someone else well known.

beer? champagne? wine?  it's like new year's eve! ~ 2 blocks to go we are BELOW 40BIL. Wow. |

it r on target chaps Let's see what happens during auction and afterwards first. However, seems that miners were briskly purchasing SP20 and S3/S4 during Black Friday. These ASIC miners (for example, SP20) can only make money (in 105 days with average difficulty rise of 5% and electricity cost of $0.12/kwh) if BTC is at ~$600. They cannot be profitable at $379, unless your electricity cost is zero. If bitcoin miner(s) purchasers are rational players as a whole, then their actions predict BTC rise. Maybe I should get one... |

Interesting news  . http://www.coindesk.com/spondoolies-tech-ceo-talks-new-asics-blockchain-lottery-device/Spondoolies-Tech is currently working on two separate designs: a 28nm ASIC set to launch in early 2015, followed by fourth-generation chips manufactured using an unspecified FinFET node. Most cryptocurrency ASIC companies do not disclose their manufacturing partners and Spondoolies is no exception. Instead of describing the new chip as a 14nm or 16nm design, which would more or less identify the foundry, Corem prefers to use "advanced process" FinFET terminology.
..Corem indicated that Spondoolies has made a conscious decision to skip the 20nm node altogether.
..Spondoolies-Tech has decided to stick with the mature 28nm node for its third-generation ASIC, despite the fact that the company's first FinFET chip will ship a couple of months after rivals will have launched their 16nm FinFET ASICs...He added that the third generation is set to launch in late Q1, or at the beginning of Q2, next year. This points to a March/April timeframe. |

It is probably too early to downclock SP30 (it will be more urgent at 80 bil difficulty), but did anybody try?
Since my machines are at the hosting sites, I was somewhat limited to try various settings.
However, is there a table from SPT that is sort of a guideline or some other reference?
Thanks
The most basic and easier way to do it is to limit the PSU to whatever you wish your miner to consume. Is this really the best way to go? Specifications call for variations of the ASIC voltage (within 0.63-0.8V) if I remember correctly. I used to lower the voltage in order to get to the desired W/GH, but jtoomim tipped me that each chip is different and limiting their voltage isn't the best way to do it. By limiting the PSU each chip can run at it's optimal voltage. OK, sounds interesting. What was the approximate PSU limit to get to 0.55W/Gh for SP30? I have seen this number (0.55/Gh) being mentioned here somewhere. I got it with an evga 1300 g2 right now I am getting 730 watts and 1324 gh. but this was with the sp20 Temp Front / Back T,B 33 °C / 69,65 °C Fan Speed 40 Start Voltage 0.655 / 0.655 / 0.633 / 0.633 Max Voltage 0.664 Max Watts 180 / 180 / 180 / 180 don't do that fan setting try 60 and in a few hours check your temps Thanks, Phil. I wonder if SP30 settings would be the same or different. The setup file for SP30 does not mention underclocking, only overclocking. |
