People always overestimate short term moves and underestimate long term.
Case in hand: look at AAPL stock chart starting in Jan 2003. It is up from ~$1 to $91 in 11 years with a lot of crashes, etc.
The major trends beat volatility, hence day trading is futile in 99% or more cases.
The wind behind BTC sail is its potential PLUS the fact that there will ever be only 21 mil BTC or 0.003BTC per each Earth inhabitant or 0.016 BTC per OECD countries citizen or 0.013 if you add Brazil and Russia to OECD.
So, if you own much more than 0.016 BTC, you will be more affluent than average in developed world in 20 years IF bitcoin succeeds

Any news from bitmain? I am pretty sure that without a word re this sale conditions, half or "orders" will skip it and order direct. miners are an inpatient bunch  |

Only newbies check the calculators. True miners don't give a f*** about ROI. Everyone and their mother had complaints about ROI going in the fall of 2013. Then boom, they all jumped on the bandwagon when BTC went over $1000. I am now hearing people talking again about ROI. Soon there will be another boom  Yep, just buy BTC like clockwork, then use some %% (I would say 10-15%, but it is different for each person) of that BTC to buy miners, get more BTC. The best of both worlds. |

It is diffucult to calculate the unknowable probabilities.
As an example, Drake equation together with Kepler data suggest that life should be all over the Universe, but so far-no indication of intelligence being present anywhere else-Fermi's paradox. My point is-it is diffucult to calculate the true probability of an event when too many variables are involved.
If you were intelligent, would you call Earth? I would text..[to Satoshi] |

Hash power improvement on hardware can't keep up with the diff.
As someone said above, no ROI, no care. And it looks like it will be the case.
you sir are likely correct....er due to bank issues...i'm a legal miner in usa (sigh) have to pay for mining profits as income (gross income 25% taxes like the rest) er those of you not in my boat run away till hopefully they fix these IRS guidelines from 2013 to something more sensible in 2015 (i think they will..just say at that point 2015 gee IRS it was a very very good year if you wan to report) heh anyway MY ONLY angle is that I can get off 25% in real $$$ towards actual taxes paid thru equip depreciation (and have credits on such from last year) so i got a spondoolies sp30 w/o being in my situation it makes NO SENSE to get equip in the foreseeable future imho in order for BTC to survive this massive equip dump and difficulty rise the price MUST go up for BTC thru increased demand or we are all in trouble and yes I may barely break even on the sp30 ROI wise due to my above (sigh so lonely) position of er ahem being a legal miner (i feel so dirty)...but i suspect after all is said and done and it probably will end of life by Dec 2014 at the rate of equip dump i will take a loss so yeah any equip you buy at this time thru fall will likely be a loss vs just buying btc imho ...it may level off etc after fall but I think it is gonna get really really ugly this last 1/2 of the year but then again they are such 'cute' little boxes..the s3's ...nice whirly sounds...pretty LCD's so cuddly . ack must resist ..its a trap ack Searing A. For all new purchases of computer equipment, you can deduct up to $105,000 of the actual purchase price, under what’s called Section 179 of the IRS code, which has to do with equipment depreciation – as long as all of the equipment is purchased by December 31. This is for any business of any size. http://www.startupnation.com/articles/small-business-tax-advice-computer-deductions/it seems that maximum deduction is $25K right now (for 2014) http://en.wikipedia.org/wiki/Section_179_depreciation_deductionHowever, congress just voted to increase it: http://www.agweb.com/article/house_passes_extension_to_section_179_depreciation_rule_NAA_News_Release/ |

S2 delivery date pushed again 30th
That's how bitmain works: you give them money first, then they send you a machine two days later. |

Ok mathmeticians, figure out the answer to this one. Let's say you had one of these 500 Ghash miners, and you could time travel back to January 2009, when the difficulty stayed at 1 almost the entire year. And let's say you put this miner to work, pimping out the hashes like a mutha. Now here's the math part: since BTC is limited to a 4X difficulty increase with each adjustment, would it be more profitable to: 1. let the thing hash non stop and let the difficulty rise over a few adjustments to its equilibrium point,... OR... 2. once the difficulty rises, shut off the big miner for a few weeks and let difficulty drop back to 1, then turn it on and run it up again? I think letting it run non stop, even with higher difficulty after the first few adjustments would be more profitable. Math it out! Do you have a time machine handy? You'll have to convince me first, LOL http://www.youtube.com/watch?v=SR5BfQ4rEqQ |

You have to add $70-169 for FEDEX ground or express. With FEDEX ground, it is $1450 |

The way I was going to do it was to run the 8 pcie to straight 6pin pcie with adapter from eBay and for the other terminal a dual sata to 6pcie also from eBay, this way your not putting too much current by spitting the 6pcie as you suggested and the sata and 8pins are on different locations in the psu thus less chance off overload
Interesting, so you will be using three types of output cords:PCIe, 8pin and sata, then use 8pin to pcie and sata to pcie adapters. Unless someone tells me that 8pin cannot be split into two PCIe connectors, each carrying just 87.5W for a total wattage going through 8-pin of 195W, I'll probably use this. |

I don't like that each S3 is going to require 4 PCI-E cables.
The EVGA Supernova 1300G2 is a super PSU that is able to run 3 overclocked S1s, but will not be able to run 3 S3s without buying 4 more PCI-E cables that have 2 PCI-E end connectors each.
I suppose the next best option would be to use EVGA Supernova 1000G2 PSUs, which should come will all the cables required to run 2 S3s.
Does anyone have any other PSU ideas to power 3 S3s?
I am planning to use PCIe splitters for EVGA 1300. Since each PCI slot will have only 97.5W load, I think that this is ok. Like these: http://www.amazon.com/StarTech-com-PCIEXSPLIT6-6-Inch-Express-Splitter/dp/B004NNTVT6/ref=sr_1_5?ie=UTF8&qid=1403821996&sr=8-5&keywords=pcie+splitthere are also cheaper brands on ebay. No way i will be buying another PSU-I have plenty already. |

Powering S3:
I have a question re Corsair CX500M
CX500M has a split PCIE connector-this covers 2/4 power slots on S3
CX500M also has a ATX 8-pin cord on which it is written: CPU. Can this power 2 remaining PCIe slots on S3 using a 8pin (F) to PCIE(f) split adapter?
CX500M also has a strange concoction of 4 molex connectors daisy chained to each other and to an unusual 6-pin connector with 2 empty slots that says Type 3 on the side-is this one usable instead of the 8pin/CPU connector?
Thanks-trying to see if I can use this power supply.

Why hosted? A real man keeps his miner in his house and uses it for a pillow.
I replaced my mattress with SP10s. Keeps me warm at night. Some people complain SP10 is a bit on the loud side I get in now why he (Zvisha) is so giddy and jocular now. Perhaps, we will see that magic number (~$100/mo) afterall....(deals in China/SE Asia)? Zvisha is giggly because he worked on SP30 FW for 12 hours straight and now he is in sleep deprivation. Then, login a huge overtime and "hit the sack", LOL Cheers |

In order for the SP30 to become non-profitable, it has to mine less then 100$ a month.
Today it would mine about 2000$ per month.
Where this number of $100/mo originated from? This is completely unrealistic anywhere, but in central WA. $0.12/kwh (with delivery; cheap in Texas)X24hrX30.5 (average days in a mo)X2.4 (isn't SP-30 2.4kw minimum?)=$211/mo. In CA-$500/mo. Miner itself is not free either. Why hosted? A real man keeps his miner in his house and uses it for a pillow. I know that you are kidding...not hosted-0.12/kwh residential, hosted-best price is $99/kwh/mo, still $240-250/mo, slightly less if a long contract Anyway, i am comfortable to wait and see how it will turn out. |

Without profit mining is dead. When mining dies, the network dies.
That's why I wonder if Wall street crowd realizes what they are doing in pushing down the price? |

fantastic! I am not familiar with the beaglebone black hardware format, but on pictures it looks much smaller than the one in S2.
I see USB, microUSB, 5V and Ethernet ports on pictures plus two multipin ports (for ribbon connectors?).
Did you power it through USB/micro USB and then connected to miner by the ribbon connector?
Thanks. I want to see if I can build S2 or S2-lite from parts.
the BBB in the S2 is exactly the same format as original. its only missing the USB ports and 5V What you see in the S2 in the middle of the mining cards is an additional controller card. the BBB is directly plugged onto this card with its multipin ports. you can "easily" unplug the BBB if you want to build a S2 you have to rebuild this card (as I think) or get it anywhere else I see...I wasn't expecting another controller card (I thought that what is in the middle is actually BB because that's was where the microSD was). This gets more complicated...thanks |

Have anybody tried regular Beaglebone black, rev B or C together with bitmain microSD card to control S2?
Did it work?
I tried an SD card with the bitmaintech firmware flashed on it and it booted successfully. i could access the web config for the miner and watch as it hashed at 0 ghs due to no asic's installed. i have NOT tried replacing the BBB from bitmaintech with this one, though, so i can't really confirm that it works. If anyone does, i too would love to hear about it. Like to know if my spare parts are usable as spares or not. I can confirm that it works - I did it temporary  fantastic!

That would be 100 amp service at 240V. You have two 120V phases coming into your house each at 100A. Five Neptunes is a lot; but, you make sure your running 3 on one phase and two on the other.
100A x 240V = 24000W
or
100A x 120V + 100A x120V = 24000W
Same power...two phases.
^^^^This. With a modest ~2kw in equipment right now, my house is already above 10kw/h part of the day due to 100oF outside. I started thinking about solar panels, but they are too darn expensive, like 15K for 5kw worth. In Texas mining looks more and more like a winter "sport". |
