I'll go for late Sunday, Aug 30 in US (which is Monday, Aug 31 in China).
Bitmain says it will be on sale Sep 30 9pm (UTC+8) At noon US central UTC is 5pm, so UTC+8=11pm US central or 9pm pacific. They say 9pm, which makes sense. Can anybody confirm? |

I have the opportunity to get these SP20s at a decent rate. Only problem is I mine in my apartment and noise is the number one concern.
Is there anyway to undervolt/underclock these SP20s so they are at the same noise level as an S2/S3 ?
Yes, If you are willing to sacrifice some Gh in favor of lower noise. lower w/Gh is the benefit. You can easily get to 1300GH/780-800W with fan at 20-30 or 1200-1230GH with fan at 10. The latter setting produces a humming soft noise (~60-61dB at 1m distance) instead of 'metallic' noise at higher fan settings. Automatic setting makes fans going up and down, so although final could get as low as setting 6, but the noise keeps changing, so fan 10 was best for me. I have family walking around at setting 10 for many months now-not a single complaint, but they absolutely hated Sp20 at fan setting 90, similarly to unmodded S5. |

But it is hard to tell if they come out and no one else has something to compete. They can do what every they really want.
Exactly. Why would they sell it cheap if there is enough demand at a higher price. And if $700 sounds like a good price for many posters here then likely there is going to be enough demand at $1000. they were in a similar position with S3 and S5 (a little less so since they probably wanted to undermine Sp20 as a competitive machine), yet the prices stayed somewhat within reason. Weak yuan/renminbi is also a factor in our favor. When s5 was introduced, everybody thought that it would be more expensive in $$. I will probably not buy anything above ~3 BTC for ~2.4Th/550-600W. |

Do they ever mention what the hashrate will be? Or, just the power consumption per Th/s as 230 watts?
I may be stretching, but a 2.4+ Th/s machine for <$700 SHIPPED would be amazing.
The 230watt / th is THE hard figure they've mentioned, though the fine print on that specified chips running at .66 volts. Presuming they stick with string design, that DOES specify 18 chips per string. It would be VERY VERY iffy for them to try to cram 54 hash chips on one hash board. Therefore, the general consensus has been 2 hash boards, 2 strings per chip, appx. 2.3 TH at appx 550 watts ballpark for an S7, at around 4 BTC PLUS shipping (or around $930ish at current BTC pricing). Call it $1000 or so shipped. There is absolutely no consensus that it will cost $930, none at all. $700-750 is much more reasonable for a 2.3Th machine, and will sell twice as many units. They can get extra $100 by delaying shipment by 2-3 weeks while "testing" |

I don't know where to post it, so will stick it here. first-i don't think that btc will correlate, except on high down days. However i found an interesting blurb on the market conditions; CNBC Pisani says that conditions of yesterday/today should exist (theoretically) only one time in 140000 tries or once in 383 years, yet then he says that we had one in 80ies (he probably meant 1987), then in 2011 and now in 2015. http://finance.yahoo.com/video/pisanis-market-open-p-500-134300969.htmlgo to ~1:55min If you still follow theories that assume stock prices are normally distributed than you need to read Mandelbrot. no, i was just quoting him contradicting himself in the same sentence. What Mandelbrot's book would be relevant-the (mis)behavior of markets? |

We havent even gotten over the major hurdle yet, and thats the current situation.
The whole xt news and bitcoin split can probably handicap this price value of every single persons suggestion on what it`ll be in the future.
Think of the now, rather then 14 years later. If people test the xt, and fail to see its any good thats when bitcoin will probably take a serious hit before any upward trend.
when i use $$ to buy bitcoin and then use that bitcoin to buy services or products, I see where bitcoin limitations are: it is in fleecing that's going on. Example: 1. buying bitcoin with $ on coinbase (not the exchange) results in 1% fee plus you pay the "coinbase" price that is typically 0.5% higher. So, for every $1 in bitcoin, you spend 1.5c more. 2. you are buying from merchant using bitpay and suddenly you end up paying 0.8-1.5% more (maybe because bitpay consistently uses lower price than coinbase) 3. bottom line: it routinely cost you 1+0.5+0.8=2.3%, which is almost the same as paypal when merchant asks for the paypal extra (2.1%) So, where is the price advantage? It is nowhere to be seen and until ALL major bitcoin merchants will introduce 4-5% discount very few people would use bitcoin, unless other payment methods are much slower. The best reason to buy Bitcoin is to protect yourself from what's coming. In my opinion only a fool would buy BTC in order to spend it right away. That is unless you needed to make a foreign transaction, or some type of purchase where a credit card wouldn't work well. The US dollar has nowhere to go but down in the long term. It's buying power continues to be eroded by many factors. Unsustainable debt, money printing/inflation, and increasing lack of confidence. Growth of the Internet was exponentially slower than the growth of crypto. Each year Bitcoin's infrastructure grows leaps and bounds. Since there is a very limited supply of many crypto coins, and fiat continues to lose ground, the real winners are going to be those who hold their coins the longest. We see minimum wage moving towards $15 an hour in many states. It isn't hard to imagine where exchange rates will be in the near future. My point is that bitcoin would not have spending utility if you are fleeced 2.1% extra if you want to buy something with it, but start with $$. In such situation, transaction rates would not move much, limiting the growth of the whole ecosystem Without serious purchasing utility, it is only a potential saving vehicle, but this thesis was severely tested in the last 21 mo. It very well may be that btc/$$ exchange rate will increase in the future, but there is no indication for this yet. I am still in favor of bitcoin odds in the long term, though. |

Last time I check with my chinese friends, their parents are buying up the midwest houses to flip from brokers.
Then again, they do probably do both, where they see the market in a downfall take money from other sources.
they can take only $50K/year out of China. |

I wouldn't be surprised if Shanghai was sitting on 2500 points by the end of the week. A full 50% down in just over two months.
shanghai opens at ~3K, but down 1.53% since I started typing edit: now -2.26% (2898) |

Panic sell is about to be completed.. epic rally to follow...
Curious to if BTC will follow the rally or ppl will dump BTC to jump back in.
rally in china or US? china-probably, but US might double dip eventually to ~1700 on SP500. fast markets-whoever bought in am was not too pleased by the eod. |

what i think an antminer s7 would be:
5.58THs to 4.68THs
power under 1500watts
price 825 to 975
just my two cents
nah, what you described is more like S8 S7: 2300-2400 TH, 505-550W ... but the $975 price point might be right  Let's be realistic here, Bitmain is not going to sell a twice-as-efficient miner for LESS per TH/s than the S5. So if the S5 is now $380 (on Hashnest) that's $330 per TH/s. It's likely the S7 would be around $400-500 per TH/s, depending on the BTC exchange rate. I think that they will aim at $700 or about as it shows 280 days until profitability at 600w, 2400Gh and $0.1/kwh electricity cost at current btc prices. |

nah, what you described is more like S8 or S7+ S7: 2300-2700 TH, 505-595W in a small form factor. It is much easier to dissipate that much heat vs 1500W however, it would throw a wrench into plans of many if it would require three separate PCIe connectors with each more than 200W as per S5+ design. It would mean that Corsair 750 workhorse is a no go. |

Thank you for your thoughts, but sadly they're no longer for sale  . I came too late. there are plenty here in Marketplace: hardware threads from reputable people and with escrow if you want it. |

They will be priced to roi in 250 days at ten cent power
most likely, but only if price stays stable. |

There must still be loads of S1, S1/3 upgrades and S3, units sitting in lonely neglected corners, all waiting to be lovingly revived with nice shiny T/h capable boards.
Bitmain are unlikely to come back with anything suitable to replace them.
Bring on the BM1385 chip. It may be old tech 28nm cleaned up and repackaged, but it could still fill a gap for the home miners and see the community through to the block reward halving due next spring.
Personally, I think that boards themselves would have somewhat limited appeal (only to enthusiasts and people with good technical skills). I am not saying that they would not be sold in hundreds and up to a thou, but maybe not many thousands. Additionally, which software would these boards run on? The underlying controller ones-might be incompatible, although probably a solvable problem. A new "community" miner, like is described on another thread would have a much bigger market . Just my 2satoshis. |

Since most people don't give it a second thought, you cannot induce FOMO with anything, really.
I gave a couple of my relatives paper wallets-so far they never used them.
It will continue like this for a while, maybe for a long while.
