RIP profitable hobbyist mining on 120V circuits.
The ROI math using assumed pricing for these beasts doesn't even make them seem that profitable for large-scale mining. I don't think any of the current gen hardware will ROI before the halving less than a year away. It's an impressive machine, but coming on the heels of the S5+ and S7 I don't like the trend of "bigger bigger bigger" in both physical footprint and electricity demand. I wonder where we'll be a year from now, 12.5 btc block rewards and 100 billion network diff... I anticipate a BIG boost in bitcoin price by the halving. We can expect the climb to begin by March/April 2016. Buy BTC cheap now while you still can. Here's a great thread to follow regarding bitcoin price and speculation: https://bitcointalk.org/index.php?topic=274613.3820;topicseenI looked at the numbers...if it is 44k for miner, you could do much better by simply buying $1260/wk worth of BTC between now and July. $1260 is the amount of income that SP50 produces in a week right now considering 8.5c electricity. By July 2016 you would have spent $44K and have all of that bitcoin vs being ~minus 8K at current BTC prices and have no bitcoin (with ~200-205 total bitcoin produced, then sold). If bitcoin abruptly goes to $600 on April 30 without much change beforehand (just as an example) and stay there afterwards, you would be able to accumulate about 191 BTC (~165 before april 30 and ~26 until July 30) vs IN THE BEST case producing almost the same amount of btc and using at least 50% (if not 100%) to pay for miner and electricity. therefore, slowly buying BTC (if you think that it will increase in april-may) is a better strategy. Check my numbers and prove that i am wrong, but sometimes the best strategy is not to play. |

The rubicon has been crossed.
RIP profitable hobbyist mining on 120V circuits.
almost...spt just announced, the machine is not available yet AFAIK. |

We could see a price tag of $47,850 to $50,000 on the SP50 quite easily. I would think the more bought in bulk, the cheaper they would be. Bulk pricing MIGHT start at 3 units. We'll see...
did you inquire or a guessed? if so, buyers would waste a lot of money...fast. with 8.5c (Great north data), and minimal difficulty rise, you will be in the red for a tune of 7.5K+own canada $2.5K for import=minus $10K after a year of operation at current low difficulty rise (yeah, right, it will stay low-NOT) I've thought about this more after my previous post. $39,600 to $44,000 is more like it. It's all kinda speculation no one knows. And I'm guessing it varies on number you purchase. So it could be hard to get a number. Anways I forgot to say it earlier congratz SP on new miner. It is one heck of a unit. Agreed... I made an edit to my previous quote as you posted that it could be $35,000 per unit with the purchase of 30+ units. Something tells me the minimum purchase will probably be close to $120,000 (3 units). I just realized that I did not take into account the fact that we will have a halving in July 2016, so these numbers are even worse. Despite being a tech achievement by itself, it has to be priced right to sell many. |

Just got my first S7 You can software control the fan speed  Thank you Bitmain! will you check if you can get better efficiency at lower settings, please? |

Something interesting if you read it "Reliable and cost effective 28 nanometer (nm) process versus 16 nm processes". It seems the ones who stuck with 28 nm are going to be the winners at least short term. They mastered a old NM instead of going smaller nm. Both bitmain and SP did this which I find interesting. Please give use a SP50 mini  . I really would love to have one with so much power. If i could get one that 1 240 30 amp breaker could power that would be great. The name sort of hints to a 11TH SP40 it does not looking good for SP40 at least for now as they did not like their SP20 experience (low profitability), unless SP40 would be organized like SP10 or SP30-now, this WOULD be sweet at 1/5-1/10 of SP50 (one or two boards) for 10-20 TH. |

Pretty sure those of use who ordered S7s will never ROI. SP50s will destroy any chance we had with the massive difficulty increases they will cause.
probably, but it is one thing not to ROI to the tune of a couple of hundred and another to have the same with 25-30K investment. I expect bitmain to go and price S7 super aggressively if SPT will price theirs at or slightly above 25K. Not a chance SP50 will be under 40k. 55k bulk pricing is optimistic. numbers that you mention would make it irrelevant, despite an impressive efficiency. you are saying it will be $0.5/GH? that would be worse than S5 and even Sp20. check the profitability calculator. |

man this thing is insane.. hard to imagine them coming out with a version for the home miner.. as zvisha said a few pages ago.. consumer mining is a dead horse, this sp50 and whatever else comes next in this large scale is the future.
I hope at least bitmain stays with the home centric gear
well, that's what IBM thought in the 80ies, but PC beat the crap out of them in volume and industry size. datacenters are slow to change their hardware, home users are quick, so agile manufacturer(s) should be able to induce faster turnaround (in theory) |

probably, but it is one thing not to ROI to the tune of couple hundred and another to have the same with 25-30K. I expect bitmain to go and price S7 super aggressively, if SPT will price theirs at or slighly above 25K. I doubt it'll change the S7's price. Maybe if they were available to the public, but they're not. Even if they were, they are nowhere close to being in the same league. Spondoolies is Intel, Bitmain is Cyrix... tech is good, but the direction is all wrong as far as bitcoin enthusiasts are concerned (bigger machines). a manufacturer with 16nm tech at 0.1 J/GH and 10-12.5Th miner at a reasonable price will sell much more, of this I am certain. |

Good news, my units just got clear from the custom !
Bad news spondoolies just release an SP50.
It's huge beast. 0,14w/gh
It's only viable for large scale mining, too big. That, and it is only available for bulk customers. So I don't think you can just get an individual unit unless you can put together a massive group buy  Each unit is a group buy! it would be doable if you can split hash from each board individually, which is a possibility, of course. |

Yeah realm this,is a game changer, I just upgraded my basement to 200amp service and also getting another 150 amps in my garage I could handle two of these units, please someone start a group buy for this now! .even with my bad electrity costs that's only $50 per day for that massive hashrate Please Guy hook us up! are you guys millionaires? dropping at least 50-52K at the moments notice. |

Just to be clear, it is 110Th+/-10%. Beforehand it was a mixed bag with SP30 vs Sp20. Sp30 was +/-, but SP20 was never a +/-, but rather - in most cases. 10% is a bit more variability than I would like to see. 5% would have been better, especially when we are talking about numbers that are so large. So, if it is 100TH, then it is 16.5J/Gh, still very very impressive for a large machine like this. |

I could run 2 of these in my garage at home
seriously? you have one mighty garage with a 150-200A dedicated box...jealous. |

I have a few names for it:
SP50 "Stegosaurus" (large and stocky, or maybe, "Triceratops")
SP50 "Dragon"
SP50 "Azhdarchid" (for scientifically inclined)
Please post yours...
How about SP50 "bitmainslayer"? I do like Gibson (from "Hackers")-see my edited post |

I ordered a unit the first day with shipping to California via FedEx. It's already in Oakland (an hour away) and will be delivered by 10:30 AM PDT. That's less than 4 hours from now! It's also my wife's birthday, but she won't see this as a present  yeah, especially since you would have to blanket it with pillows or foam |

What is the price per SP50?
has to be around 25-26K shipped to be competitive considering that competitors can lower their prices. ~180 days to profitability at these numbers. Probably more, it includes PSUs. These are 11U = 24 x 19". 6x 120mm fans = a grid of 14 x 10"s of fans And so the 10x 1600W PSUs *appear* to be the same 1U ones from the SP35 (Artesyn DS1600SPE-3). In a pack of 48 they're upwards of $400 per unit which is probably approaching $300 with Spondoolies quantities. So that's $3,000 of PSUs. Shipping will almost certainly be palletised, those things are way too big and heavy to go through normal routes so that's a fair chunk but not really different to anyone else. more will be uncompetitive, especially for low electricity cost regions. they will probably promote selling "shares" in Sp-50 (at 10Th each or so) |
