A malicious government could totally make a 100mW data center, fill it with hardware and "attack" the network. I don't see how they could not. Now if a government is going to want to sign off on such a expensive, open attack.. i very much doubt.
Doing this would piss of a lot of people.
There's probably more covert ways to go about this.
Is it generally certain that all current hashrate is more or less accounted for, and not, in fact, a malicious government running some operations covertly right now? How would a government building a big data center be some malicious operation, if its pointing its hashrate at a legit mining pool? You're wondering if they just plan on mining a ton of BTC and then dumping it to hurt the value? Or they're just mining to cut their losses while they spool up some their 1 exabyte datacenter? Well they're better hurry up, because soon, that won't be enough. It would be much profitable for them to just earn through mining instead of dumping to hurt bitcoin. They can't win this battle anyway so they might just wanna join with us. This a is much better option for them to which they should think about. They definitively, easily can "win this battle". Its not hard to crash the price of Bitcoin if you have billions of dollars alloted to doing this. The feasibility is not the problem. Its the inclination and the international impact. There is no point to do this if you're some lone country that goes against all other countries and attack Bitcoin. And if all the countries want to get rid of Bitcoin, then they can just consensus to outlaw it at that point. Something that does not do much when you're a lone country that decide to outlaw it. It would make more sense than spend a shit ton of money. |

Does S7 have a voltage setting in the ui?  I guess I saw it before upgrade to December's FW... It can have it, but it does not do anything. A design that allow software control of volt would be great, but this is just like the S3. Unlike the S4 which the software disabled the software control for unknown reason, which you were able to re enable with custom firmware. That UI setting just set the value in the config file, you can instead simply write the value directly in the config file, but its not going to do anything either. |

Have not bought any of the current and I do not intend to unless prices come down for equipment and the energy use comes down to. Maybe in the future after halving some massive improvements come to the asic world and provide a lot more effective units.
The current S7 price is great, asking for cheaper would be a bit wishful thinking. At the moment i would ROI one in 4 months, that is pretty great. Having even more efficient hardware would not make mining more profitable at all. If they come up with 0.01J/GH unit, then everyone will have those, and your profit/watt will be about the same as now. Right now, the Avalon6 is a great unit, but the price is not keeping up, so this show that you can't really expect things to suddenly be super cheap, affordable and great return for you but not be for big operations that pay 10 time less for electricity than you and get cheaper deployment cost/GH than you. Your btc profitability is pretty much forever locked to a range, based on your electricity rate/what deal for cheap hosting you can find. |

Never had a problem. For your S1 and S3, it should work great. And if you decide to buy another S3 one day, you don't have to buy another PSU.
Is there a big red "bulllshiessen" button on the webpage for me to press? Preferably which sets off flashing red hazard lights and honks a comically loud klaxon. An S3 and an S1 on a 750W 12V rail would have to be so underclocked that you'd rather not do that. Look up the power specs of the model and series number of your miners. While you are there, look up what one series-8 S7 would use, since planning ahead can sometimes be a good thing. To, for example 360W for your S1 add a bit for overclocking headroom plus current surge when fan speed is increased. eg 420W. Do the same for your S3. add the two numbers together. It won't be inside 750W, and that ATX trips a shutdown at exactly 750W, even if you go a little bit over for much less than a second. Exactly ! 1000 watt seems more logical or 850w I dont want to RMA a second PSU  and also no underclocking for me , maybe about 2 months later i will buy a 1600 watt bitmain PSU , but for now i need something cheap nothing special. and tnx for the suggestions ! ;  I don't know why you would want a 1000 watt PSU for a 470watt load. Unless you're in the business of running the S1 at 200GH/400Watts, at which point something like a EVGA G2/GS 650/750/850/1000/1050 are all valid options. Depend simply how you intend on expanding later on. wooow those EVGA's are quit expensive , VGA SuperNOVA 850 G2 @ 150 euro's and the corsair cs850m starts @ 126 euro EVGA SuperNOVA 850 B2 @ 125euro @ , Yeah, but when i say they're good psu, they're GREAT psu. You can't compare a EVGA g2 850w to a whatever 850 watts. The EVGA g2 850 will run 940watts at the wall 24/7 with great efficiency and clean power. And 10 years warranty so any talk of PSU degradation that are moot from the start become completely irrelevant. |

Yooo I will definitely compare some of those EVGA's ! or this 1 ? http://www.lc-power.com/en/product/netzteile/metatron-series/lc8850iii-v23-arkangel/ this will also do right ? for my next miners i will just go for a bitmain 1600 watt , or some other PSU from the miner store , i always forget that the seller also have good PSU's in the 50 euro range ! But this time i will write it down somewhere so i wont forget it the next time when i am planning to expand! . anyway tnx for your suggestions  If you go for a cheap PSU, you're going to get poor result, as simple as that. The EVGA is well EVGA, G2 is a serie GS is a silent serie, there is no difference for a miner. Search in your favored electronic retailer either EVGA G2 or EVGA GS. Anything 750w+ will do for overclocking both unit. 650w will do if you do it the reasonable way. Anything higher than 750w if you plan on upgrading, depending on how you plan to go about it. Its a bit more expensive than going for a decent corsair or a good seasonic, but i get to push my miners higher with these. And 10 years warranty. |

An undervolted S1 run easily 140GH/s at 160Watts. Then add 355watts for the S3 at stock speed. Thats a total of 515watts. I don't see how 515watts is greater than 750 watts. Then 2 S3 is 710 watts. So the post you replied to was absolutely right. But this is when you underclock all the miners right ? Really its hard to believe it will work and i also want a bit of room to OC both ! A S3 is 355watts at stock speed, 450 or so GH/s. You don't underclock it at all. You can try to overclock the S3 but it won't go much higher and it wont take much more power either. You can overclock your S1 as well if you want, which is pretty much a waste, but you can. I dont see the point of consuming an extra 240Watts for 40GH/s, but thats up to you, not me. Which is where any of the EVGA i recommended comes into play, they all would work. |

250k start-up and asking for advise lol. 1 Post and no doubt never to return or even read maybe read as guest. If you got that much I would just buy crypto save for the future and not bother to waste time on mining. Just learn how to trade crypto or get someone or some people and a team to trade active and make a business out of it trading daily and making a good income and future from it.
I would totally bother mining with a 250k Startup, but you're right, i don't think OP is serious at all and replying here is not for OP, but for whoever comes by here looking for some ideas. Best wait for someone serious, with some real questions. |

Sell your S1 as soon as possible, they never make ROI. You eventually lose money. Even S5's make ROI very hard, S1's are antiques now. Bah, for you. At 0.06 they are still profitable for me and they will continue to be for quite a while. The BTC at the moment is so high, anyone with decent electricity rate can pretty much mine anything and profit. It's impossible to ROI even you have free electricity. I wonder how do you calculate that and turn into profitable? What are you talking about? At free electricity, they do 10$ per month, if you buy 10 for 200$, then you have 2 months ROI. Mines are already paid back and ROI'd a couples of time, now at 0.06$/kWh, they still profit 2$ per month, clearly not much, but since i'm using them to heat my bedroom, this is pretty chill and they make 0 noise with the 17 dB 70CFM fan i have on them. 140GH/s @1.15J/GH |

Could a powerful enough entity with huge resources develop enough hashpower privately to build the difficulty rate so high that if they removed their hashpower from the network suddenly, it would crash Bitcoin economy due to new blocks taking hours (or days) to confirm?
Plausible? Possible? Impossible?
Explain.
Thank you

Twister bearing, aka "rifle" "hydro" etc is nothing more than a fancy sleeve bearing type.
I recommend AGAINST any version of a sleeve bearing on a fan.
Manufacturer MBF ratings from most fan makers tend to be wildly optimistic, assuming lab-level CLEAN AND COOL conditions among other things - ball bearing fans tend to be the ONLY ones that actually achieve their rated MBF in REAL WORLD usage, and even some of THOSE are rated somewhat optimistically.
That's one of the reasons "push" is almost always better than "pull" for cooling - the "pull" configuration runs the fan a lot hotter, making it a lot more likely to overheat and fail faster.
Thanks for your though, I'll take it in consideration when ill receive and test it. It should be fine, those fans apparently are easy to clean, which is where the real problem is for real world life time of the unit. (The item description mention that the fan is easily detachable for cleaning) Its like those GPU fans i have on my 280x, i just pop them off, clean them with a qtip, at a speckle of lubricant and they run like knew for another 6 months. (And again, 3 times now) I vastly prefer fans that don't NEED cleaning, as fans that get dirty and stop running tend to KILL electronic gear before you get the chance to notice the fan died. Ball bearing fans are a TON better at "don't need cleaning" than ANY sleeve-bearing or varient design, as they're designed to NOT NEED LUBRICANT JUST TO RUN AT ALL. I'll take a "40000 hour MBTF" Delta over any "160000 MBTF" piece of junk sleeve/hydro/rifle/twister type design, as the Delta might actually last that 40000 hours where the sleeve/hydro/rifle/twister/etc. type design will be lucky to make 10000 before it locks up the first time, and will probably have completely died before 20000. Oh no, you have to clean it every 416 days, thats a shame.(?) Yes i clean my fan once a year, and for that year, they make no noise. If you prefer using fans that are 8-10 time louder because they will do your 2 years of miner use without slowing down (they will just rattle even more loudly), then thats a-ok with me. But i don't see how you can rationalize quiet fan lasting 1 year without needing maintenance is "crap fans". |

It's a new computer with an Intel core i5 processor, so I don't think it's the machine that's slowing things down.
atm, I'm watching a film on utube via the same wifi (but using the Chromebook), so I expect that slows down the download.
Well its 50GB and every transaction need to be processed, one by one. Its massive, thats why you dont use Bitcoin core if you're just a regular user that need a wallet. You use SPV for that. Bitcoin core is just for running nodes at this point. |

I do not think is correct, the price difference, should cost the same price of the batch 9, because it is the same hardware, same power, nothing changes, this is only a policy to make more money, and all that we allow ourselves.
cmq I need coupon for batch 8, you have something to sell?
I do not think you understand. Getting a S7 1 month earlier mean you generate 1 BTC in the meantime. So the hardware is worth a bit more. If you do not understand why the S1 was worth hundreds of dollars a long time ago and is now only worth 40$, then i guess there is not much else i can say to explain it to you. |

Thats just how it works. The sooner a miner can be delivered, the more it is worth. Its not stealing, thats how it has always been and thats how it always will be. Imagine getting a S7 1 year ago. Now imagine getting a S1 now. The result speak for itself. |

Very high hash rate
Also have youtube video
I cant find in china yet .... I find in Malaysia from alibaba.com
I very much doubt some unknown ASIC maker is making better ASIC than the big ones that spend insane amount of cash on R&D. I'd be very happy if you could prove otherwise, but i'm pretty sure that no matter the retailer, Smart miners are non existant and only a tool for scamming. |

Bah, the 1.2mW they listed was their consumption, not some rated number based on some regulation i havent heard of. But it does not really matter, as the math is for 1 mW consumed, if a 30mW only use 80% of 30mW then its going to use 24mW.
Then i'm not sure what you're going to be doing with the 3% you're adding, fans, maybe? There's no way a facility is going to be using 240kW of fans, but what if they dont need fans in the first place?
Anyways, the math for the SP50 was already done in the post you replied to, its about twice with S7, which sum up to 70-80PH/s. Albeit perhaps lower than actual 70PH/s if you start factoring in additional electric consumption overall. I can't say my numbers were conservative at all.
If you do simple quick dirty math of 10000 (kW) / 16(kW) you got how many SP50 you fit per mW. Then you multiply that by 110TH/s bam about 70PH/s.
Therefore a mine consuming 10mW would get close to 50% of the new total hashrate. Kinda crazy.
I totally agree with you about not using 240kW of exhaust fans. IF they are located in a warmer climate, they would use AC for cooling. IF they are in Iceland, Sweden, etc... they would not need it for AC. The etc. was mainly for AC but would also include exhaust fans, lighting, etc... It would probably be more like 100kW for AC and exhaust fans but it depends on the size of the facility. BY THE WAY, BTCS has 3MW total at their facility in North Carolina with racks prepared for SP50's once they are rolled off the assembly line: https://www.youtube.com/watch?v=DgHuyItPUfgIf a mining facility had 10MW available for mining [Typically reduced to 80 [IF not 75%] and had gear with similar efficiency and hash rates as that of the SP50, we would come up with the following figure [I will use 100kW for AC, fans, lighting, etc.: 80% of 10MW is 8MW minus 100kW for peripherals = 7,900,000 watts. 7,900,000 watts divided by 16,570 watts each = 476 SP50's 476 SP50's at 110 TH/s each = 53,360 TH/s OR 53.360 PH/s. The present network hash rate [According to bitcoinwisdom.com/bitcoin/difficulty] is 666 PH/s. Most every data center [Like BTCS] that tells you, for instance, they have a 3MW facility. That's what they actually have, not what is available for mining. Most any data center will tell you they are limited to 75 - 80 percent of their available power. If their facility had 10MW available for mining, they would tell you. If they just say their facility is 10MW, I would suspect they can only do 70 to 80 percent of that. I could be wrong on this but BTCS, for instance, does not say specifically if their "facility" has 3MW available for mining or is it just their facility has 3MW service; of which, only 75 to 80 percent of it can be used within NEC guidelines without Main Service Breakers UL listed at 100% usage. Hmm. Well, it does not really matter. Not sure where your power for peripherals will go, unless you use millions of RasPi, i think you'll be fine. And you're right, i added a 0 at the kW for some reason. It would be 1000/16.5=60.60*110 6.6whatever PH/s per mW. And then Gridseed said they were going to roll out 0.06efficiency i believe? Then that would be about 15 PH/s per mW. |

Oh, this is much smaller than i had imagined. Well i suppose the heattsink probably dissipate more heat more easily. If you can run that fan super quiet, i think you would still be able to handle 400mhz on it. A pretty nice performance for the stick at that point. |
