The SP50 would need to price in the range of 120-150BTC to compete
Surely you mean 80-90?  No way. Bitmain is selling 0.25w/gh at about 1.4btc/th. This is 0.15w/gh and includes power supplies, but also a 'bulk priced' device, so i would expect 1.2-1.6btc/th. That said, I'm not buying any hardware until my bitcoins are worth at least $300 again. Otherwise you will never earn back the btc you spend (like buying hardware with $100 bitcoins in mid-2013) |

A few questions for Bitmain.
1) Spec says 100V - 220V. Are these ok on 240V?
2) What is the capacity of the on board battery?
3) Is the battery only suitable for charging USB devices or can it also power the router without mains connection?
4) Does the Router continue to Mine when on battery power?
5) If the battery supports running the device, what is the battery life?
6) Is there a more complete Specification / Manual that answers these & other question?
Thanks
Rich
1) the router certainly runs on either 5v or 12v. The voltage rating applies only to the adapter sold with it. 2/3/4/5) what on board battery? I don't see any mention, but would assume any battery is simply to maintain rom/clock and not actually significant capacity. Certainly won't be for mining or mobile use. Afaik this supports 3 main uses: A) basic WiFi network for anyone who only has a wired network/modem. B) novelty/collectible/"lottery device" for non-profitable mining C) if it can connect to WiFi and act as wired access point it would solve the griping over lack of WiFi in mining hardware. You place one of these and a network switch in your mining farm, and save yourself costly ethernet installation through the walls/floors of your home If it does the wired AP or wireless repeater effectively though, it could be a decent device useful for more than simply mining |

still no word on the prices?
nope not yet. All silent on the front Looks to me like Bitmain reduced to some extent the top possible price, since they lowered the price of Batch 2 & 3 of the S7. Spondoolies would seem to have less room to maneuver now in terms of price (IMHO). this. The SP50 would need to price in the range of 120-150BTC to compete |

I will chime in since I just installed a 7.65 kW system mostly to offset my electric bill from mining, however, it is completely a grid-tie system. I paid $.65/watt including shipping (bought from a wholesaler on eBay), $2800 for 2 inverters, installation was $1.10/watt (1 inverter would have worked if I went with SolarEdge w/optimizers). I had to take a break from mining when my Edison bill hit $900 last November for running about 8 TH. Not entirely sure if this system will help in ROI for running S7s, on the other hand, Edison buys back extra power @ $0.9/kW $0.09/kW..
so you spent around $15,000 for 7.65kW and no battery packs? IIUC, that means you should get ~7kw*12h = 84kwh/day (~$8), and it will take roughly 2000 days, or 6-7yrs, to pay back the system cost assuming no surprises as i understand, thats not too bad since solar insallations are typically advertised as around 10yrs to break even, at which point you might need to install $4000 of new panels to keep running another 10+yrs |

Can we get back to discussing the SP50? 2 pages of random ass stuff...
Hard to discuss what isn't yet in the wild  Seriously though, why is BTCS stock not leaping up on the news? Because it'll take a lot to turn around multi M losses every quarter which is a risk. Think how many SP50s that takes to sell even with a nice margin. Overall though they've got a good chance with exclusive(ish) control of the SP50, with enough capital they can just mega farm their own btc at cents on the dollar. My thoughts exactly. This puts them hot on the tails of bitfury and KNC (presumably those two taped out <0.06w/GH or are trying to) and the stock is effectively a share in a hardware manufacturer AND mining company. granted that the current evaluation may not be 'right', I still expected to see a >0.02c movement based on the news |

You can negotiate for commercial contracts that don't use time-of-use here in Ontario as well Prelude. The actual rate for commercial customers between 50kW and 5mW peak is under 3 ¢ CDN / kWh, however you are again subject to the Global Adjustment rate, which at present makes up almost 80% of the cost of electricity. We have the liberals to thank for that shit show.
yeah, ontario baserate is meaningless since the fees make up such a huge part of it. that $0.03/kwh probably averages out closer to $0.07-0.09/kwh on billing |

But the 440 PH/s of hardware already exists
yes, but going by the lovely "help! my miner caught fire!!" threads or "Why doesn't my Miner work any more?!" threads every once and a while, guess what is going to disappear, especially when there is no one to make any more? just like Rockminer and their hardware, you think I could get my boxes replaced? I thought the whole idea was bitcoin not to be centralised. I thought "every CPU (miner) has a vote on the blockchain" Nah, its all there for corporations to make money and capitalise on the peasants to give them the transaction fees, just like the big banks do now  all im hoping for, is the day there is no more coins to mine, only transaction fees.. just like the end of the gold mining boom, there is still hobbyists mining, big corp or 2 making enough to pay for the mining, with government subsidies, and the guys with enough money to dig their own hole with licence to mine at that premises.. but anyway, why did I call the CPU/GPU mining times the dark ages not the golden age? I dunno, less known times then? the past? before I really got into it? Still.. SPT better sell them smaller models for the rest of us, I'm happy to buy one of them blades in that case (since there is 10 of them in there, that would leave me with 11TH/s, hella better then my 50GH/s) only a small portion of miners (geneally the first generation or two) have any significant (>2%) failure rates. most of the bitmain/SPT gear is extremely reliable and could last for years still. bitcoin was always going to centralise slightly. satoshi pointed that out at the very beginning and understood that in a short time mining and node operation would become limited to datacenters and geographic areas wit cheap resources. If you pay $100/kw/month to mine at home, and someone else can get power+rent of a larger facility for $60/kw/month, its obvious which one will get squeezed out. IMO, its crucial to understand that 'decentralized' means "no single person in control". Even with the trend to large datacenter farms, we are still looking at dozens of major pools (consisting small and big users), multiple manufacturers, hundreds of mining farms that draw >20kW. A few years ago everyone was worried that a bad person/gov could buy up $5,000,000 of hardware and conduct a 51% attack. That would now require ~$130,000,000 which clearly demonstrates a more secure network. |

well what do you know, another item to centralise bitcoins.. all we need is 2 or 3 warehouses in china doing mining, forget the idea of splitting it up over people.. And all this is going to do is increase the difficulty to unreachable heights, rich get richer, poor get poorer.
Its going to take me more then 11,000 years to hash a block, 1 year ago, only 11 years, year before that, about 6 months. you know what will stop this? mega-hashing "companies" go bye bye..
You'd think there is more profit in making little pod miners for the masses then massive rack units that require industrial grade power supply, yes?
and if anyone says "but the U3 didn't sell well" it had a major bug, that never got fixed, no one wanted to buy it.
look at the usb block eruptor, they are still selling! but nooo, lets make industrial grade miners and forget the little people, they can go "cloud" mine off someone.
so, tell me people, what will happen when the 3 major ASIC companies go bust when BTC drops price again?(begging the question, i know) back to CPU/GPU mining for us.
am I the only one to be angry at this? that these ASIC companies listen to the ones with the big racks and cash?
enough of my ranting.
Firstly, Im not sure what you mean about 11,000 years to hash a block, or how a crash in BTC would magically make CPU/GPU>ASIC. The USB block eruptor is a pathetic device (its cute and a teaching tool, but you wont make a profit) and theres virtually no sales of it for the last several months. It simply doesn't make sense to spend $450 / 1Terrahash when you could pay only $3,500 / 10Terrahash or even $30,000 / 100Terrahash. If someone is making a profit mining a small amount of bitcoins, it only makes sense they invest more money, buy the best hardware, and GO BIG. economics 101. The smart layperson will buy shares/hashrate in a company they believe in (be it a manufacturer like BTCS, or contracts at a mining pool like westhash) if they wish to support bitcoin, or otherwise the bitcoin price must rise high enough that residential electricity rates can still turn a profit (while industrial miners make *even more* profit due to having the best hardware) I would not be surprised if there were 50x as many customers of the SP20 as there were for the SP3x series, yet similar overall revenue due to the fact that many SP3x buyers were buying >$20,000 at a time PS: I was watching the BTCS stock all day today, and it didn't even flinch from the news of the SP50. I thought it would jump up on the news that there is a new hashrate to sell and mine with? |

So talked with a rep on the phone and it looks like US Customs flagged 1 out of 2 total packages and now I have to pay $39.74 in taxes / duties / import fees.
She said customs probably overlooked my other package which is why only one was flagged
I didnt realize we have to pay these fees in the US, and what a bunch of BS that 1 must have made it through without discrepancy, but the other requires this fee? when its the same damn thing
I thought we're not supposed to pay import taxes if it's under $2.5K. Must be nice!!! Here in Ontario we generally pay 13% tax + brokerage + duty (if applicable) I'd love to pay $40 on an $1800 package! I would probably love to have your power costs though. I imagine you are paying no more than $0.05 to $0.06 cents per kWH? Ontario not so much, they pay about CAD $0.14/KW I think. Quebec is better at CAD $0.08, but you have to put up with living in a shit hole province. yeah, that's about right. ontario residential has time-of-use variable rate (0.08/12hrs, 0.12/6hrs, 0.15/6hrs)(plus ~0.02/hr in various fees) so the average is ~$0.15 CAD/kwh (~$0.11USD). I have some of my older gear on timers for nighttime only, and my spondoolies change their settings 2x/day to maximize income. meanwhile in quebec its closer to $0.09-0.10CAD/kwh ($0.07usd/kwh) once you consider all the fees+charges, I don't beleive they have time-of-use, at least for industrial usage. but we get screwed on import taxes for basically anything >$100, I remember back with the S1 bitmain would happily mark it as $200/ea |

This thing looks fantastic. Price wise, I'm guessing they will aim around 27-35k.
Would love to see an sp40 that is 10-20TH, or alternatively an sp50 that comes with only 2-4 blades and can be easily expanded as price/difficulty move

It does look kinda damaged to me. The light shows all the tiny scratches tho... Is $100 the lowest he will accept? I may take it for something around $50
$51 now its an auction |

I dont know what the material is exactly, but i compared them to my poker chip set, and they look like the same. Definitely plastic of some sort.
but.... YOU made these? |
|
|

this is clearly geared towards s7 so why add the 6pins connectors on the board?! just solder directly the wires.... also half crimping or whatever is called on the wires...
the monster will fit perfect between s7s on its side and ~5cm higher for good airflow
this is a good point - a version with a multiple terminals (possibly with their own secondary power switches) might be cheaper to build and the 1-ended wires (I sell these and also PCIe-PCIe in my sig *shamleess self promotion*) are about 10-15% cheaper |

i have moved from this pool.
been mining 3 months i bearly got 1btc in that time feels like something is wrong.
Looking at the address in your signature with Eligius's stats (16evXY9azcbYtLdKCAn1SeNN7gGxcRGRi6) you've earned 0.89838518 BTC by mining sporadically over a several month period at a max of about ~2.4 Th/sec. The BTC earned reflects nearly 98% shares rewarded (better than any other pool after considering fees and orphans). So basically, you've earned exactly what you were supposed to based on what you've contributed. If you would have mined continuously for 3 months at 2.4 Th you would have earned roughly 2 BTC (estimating, since I don't feel like doing the math for all of the difficulty values for the past 3 months). But you didn't. Your average hashrate at Eligius for the past 90 days was no where near 2.4 Th. It was 1.07 Th/sec. 1.07/2.4 = ~44.6%.... 44.6% of ~2 BTC = 0.89166666 BTC.... hrmmm... looks suspiciously like exactly how much you've earned. In summary, you don't know what you're talking about and I would appreciate it if you would actually understand how these things work (or ask maybe?) instead of accusing the pool of scamming you. -wk sm-sm-sm-SMACKDOWN!!! any likelyhood that eligius will offer an XT-based pool in the near future? I considered moving to slush but dislike the need to make an account. mining with the payout address on eligius is a much smarter method |

whats with the misconception that small miners need to run a fully-validating node? anyone with <$100,000 worth of mining hardware will be mining through a pool (such as eligius, slush, etc) and only needs to be capable of downloading very basic speeds (<20kBps) anyone with >$100,000 worth of hardware can afford to pay an extra $200/month to operate a top-of-the-line satellite/fibre node. any pool with more than <$100,000 worth of hardware mining to it should be getting enough fees to host the pool in a location with insane levels of bandwidth (like a datacenter) bitcoin becomes decentralised when the mining payout greatly exceeds the network difficulty. everyone, even in places with expensive electricity, can make money when the value of block reward+fees exceeds the deployment of new hashrate. In that case, its desirable to increse the number of users/transactions to produce more fees. |

Tough question. There are several "features" of bitcoin that seemed good ideas at the time; but now, in hindsight, they seem to be mistakes, and Satoshi himself would probably agree.
So, one problem that would have to be fixed is making it unappealing to hoarders and speculators.
so make it a bad investment? Then the value of 1 coin would be determined by its use for e-payments, according to the money velocity equation. thats basically how it works now. people buy bitcoin for that the market feels it is worth. economics 101 Another problem is ensuring that its value stays in a bounded range, so that ordinary payments can be expressed without too many zeros before or after the point. Say, between 0.01 and 10 USD. In the first extreme case (about the value of 1 yen) one would not need decimal fractions, and do all accounting with integers. In the second extreme case, one could truncate after 3 decimals (i.e. use the "milly" as Americans use the penny). do you mean to keep the value low such that people dont need to use "mBTC/uBTC/satoshis/etc"? Most bitcoin software allows you to send payment in mBTC or $USD (converted to BTC value). having decimals is not a bad thing, and if that is a problem for some people even when thier wallet software does the 'mBTC/satoshi' conversion its an issue of ignorance. A stable value would seem to attract hoarders and investors, but hopefully the two goals can be achieved with built-in demurrage (negative interest). Namely, each UTXO loses value at (say) 2% per year, so you can spend only 0.98 BTC of that 1 BTC that you earned 1 year ago. Those 0.02 BTC would implicitly go to the "Bitcoin Treasury" and would be redistributed as block rewards (so the block reward could remain constant forever while the total amount of coins in circulation would still be bounded.) you already pay fees like this via transaction fees and via the network currently inflating at ~12% (dropping to 6% next year). The concept of 'inactivity fees' is sheer insanity and does nothing but make miners rich like bankers. Hopefully that negative interest would be enough to dissuade hoarders and speculators. again, you talk about making bitcoin unappealing so that it is not desirable as a store of value, why? Another problem is the centralization of mining. That could be fixed by keeping the block rewards too small to make mining into a profitable industrial activity. But that may conflict with the need to put more coins in circulation as adoption grows. when block rewards are low, bitcoin becomes MORE centralised, because only those with cheap power can profit. home users are squeezed out by residential power rates and you're left with only datacenters that get power for <$0.05/kwh. your 'solution' would serve to drastically centralize the network by pushing out the small-scale miners There are also non-technical problems like anonymity, non-reversibility, lost coins, legal jurisdiction, ... but each would be a long discussion in itself... anonymitity is a problem? or is the problem that anonymity only goes as far as methods used by the user (such as mixing) non-reversibility is a fundamental concept of bitcoin. As is the ability to lose coins (or rather, being unable to forcibly remove coins from an address you don't control). with respect, many of your ideas to improve bitcoin fundamentally damage its functionality and value |

very interested. id likely take 1-2 of them.
dps2000 is nice because you can use any fans you like to control noise levels
