before asking the question it is better to interduce what i am using in
Antminer S7 (Bought from BitMain)
BitMain PSU (Bought from BitMain)
220V & 10-16A & 3*0.75mm^2 Power Cord for the PSU
A DAIYO laptop power protector which supports 10-16A & 250V (http://www.daiyo.com.sg/index.php?route=product/product&product_id=110)Yesterday I recived my antminer S7 so when I had connected PCI pins i connected the PSU's power cord with that laptop power adapter i said. Then the antminer powered up with variable fan speed. Then i connected the network cable then when i was going to sit in front of my pc to config the antminer it just powered off and i didn't understand which one powered off first PSU or Antminer but they both had turned off. i ran and unplug the Power Cord (It was very hat) so that i thought that the pwoer cord may has burned so to test that i connected that to my compuetr psu and my computer didn't powered up so then i knew it that it was burned but 30min after my father test that again and this time my computer powered up . what is the problem ?? Pleas help What made Antminer to turn off automatically ?? Have i done anything wrong ? Someone told me i should have used a 3*1.5mm^2 Power Cord is that the answer ? Has the antminer been damaged ?? here is a picture of my antminer  Where do you get stats for the surge protector/adapter. Just looking at that thing it looks pretty cheap. Is it truly rated for this kinda power? *read the stats on back of packaging. Have you tried without that adapter even though it say's up to 16a just looks cheap? And I could be off base and it is perfect. Just have not seen anyone post before that I know of using a 8 dollar dollar adapter for so many watts. |

If you wanted to host S7s with us in Canada it would be 7 cents/kwh. We can provide references and everything else you need, we're coming up on our third anniversary in April. Email me james@greatnorthdata.comDo you think it will be profitable for you after the block halving? The difficulty is rising too fast. If the CAD increase in value against USD, you might make a loss. I think that the major factor of profitability of mining after the block halving is the price of bitcoin. If bitcoin does not rise, or actually drops, it basically means that mining revenue will instantly halve! Another big thing is the actual mining gear. Assuming next gen on most companies comes out before or soon after having, they might be a decent factor. Efficiency is a big deal already for a lot of miners, and will only become bigger. Right now kinda hard to say with difficulty looking high right now. |

ok so fan is nesary then just want sure how to put it together on a 7port hub if i put chips in 1, 3, 5, 7 slots
Normally is you have space yes you leave spots. But it is not something that will stop it from working if not spaced assuming there is enough they don't touch. So it really all depends on hub you pick. Also some hubs are better then others with amount of power from hub. What hub are you looking at? |

I'm thinking the diff increase is mostly due to the antminer s7 batch that shipped out around Jan 20th, so people got it a few days later and then turned them on. There may still be hope.
I'm not sure your talking about a lot of S7's if so. It could also be them build more S7's to sit in spots tilll after holiday when they start shipping again. Still not sure though, it could be next gen starting to hit. One of these day's if not yet bitfury is going to be pumping out a lot of gear. All I know for sure is bitwisdom looks worse and worse: Bitcoin Difficulty: 120,033,340,651 Estimated Next Difficulty: 142,496,809,802 (+18.71%) Adjust time: After 827 Blocks, About 4.9 days Hashrate(?): 1,038,662,429 GH/s |

Most of the people would suggest to do the signature campaign because it is an easy work.
yea but was old days now they are strict in what topic and section on forum they want to advertise so you must follow rules to keep in the sig camp they dont allow to post crap and mainly in off topic ,games and round, and some in altcoin section.... there are still ways if you are good in programming you can make here good money It's a good bonus but I would not consider it easy work. If you truly do decent post's it takes time. I know i really enjoy this site so I'm on it a lot. Doing many things including reviews, as mining is my favorite way to earn. But time adds up. I think people who are posting just for a sig campaign are doing it wrong. And a lot of the ones who do this eventually are banned as content is not up to par. |

There is nothing you can do. I doubt they take it off as you did deal in carding from it. Even though it is past likely that will follow you. Things such as that are not supported and will get you negative feedback.
Do you see that carding is illegal? And why people don't support it?

My last email guys:
RE: AW: AW: AW: AW: AW: AW: AW: AW: Contact Form
*************
09:23
A: YesMiners
Good morning,
I haven't any trace yet of my requested refunds.
Can you update me please?
I'm sorry but things seem going bad, I just want let you know that if I will not have my money back within thursday, I will be constrained to take legal measures (police and legal actions) against your company.
Sorry, but I have to be clear.
Otherwise, I wish you a good job.
Best regards,
Ing. ************
Sadly I think you will find it's hard to go after these scam companies. They set up with a rendering and try to sell miners. NEVER buy a miner based off a rendering from unknown company. Best of luck with legal action, but I think you will find them hard to go after. Most likely they ride into sunset with most of money sent to them. I almost got taken by one once terrahash, but paypal saved me. They had looked great at one time... but slowly it fell apart and they rode away with most of money. A few sued don't know if they actually got anything. Winning a case and getting money are also two different things. |

Lets start with:
-Where are you located in the world?
-What are your electric costs?
We can move on from there once we have that established.
in Ukraine electric costs 0,03666$ -1KW How is reliability though? Is the grid pretty stable? Even with so low of cost I don't see few going there due to possible government issues. Not the most stable environment it would seem with fighting there at least in news. |

Get brand new, most efficient miners available. If someone is selling his used device, it most likely means that it's becoming unprofitable.
not really, maybe he has bad electricity to sustain the mining in his house, but if you have a cheaper electricity than him it can still be profitable for you so it depend, certainly i would pay far less if it is used, not like the beginning where many were buying at even higher price than the new Used mining gear is usually totally overpriced. You can even find 0,3GH USB block Erupters for about 25$. Offers with fair price are the minority of the second-hand market. Of course, you can consider doing the same thing - selling your gear with the price 2-3x of it's real value, and consider this income as a part of ROI  In general, recently released devices are more energy efficient and then profitable, than their predecessors. It will be ideal situation, if you could buy used miner right after introducing, for the price lower than you would pay for a new one. The longer you wait to get even recent model, the less time you have to make an ROI. Some keep those up as collectors though. There are some who have collected every color on block erupters for fun. I did not do it on them but I did on compacs try to get every main version. So I can understand the collecting for fun. Makes sense to me. Also, some people just want to be a part of mining community, they like the process and all things related to it - in that case profitability is not the factor to be considered. USB miners are very convenient and electricity costs are not worth mentioning, so they are ideal when you want to mine for fun When it comes to mining you got the 1) Miners who want to see profits, the business miners 2) Miners who want to be part of bitcoin and mine it, but also earn back their investment, most of us belong to this group 3) Miners who want to be part of bitcoin and can accept a little loss. 4) The group who try to be one of the above (1 and 2) and fails Only the business miners can achieve ROI these days. The've got better prices both for PSU/Asics + electricty It's getting harder and harder for hobby miners, the difficulty level is biggest factor I think. If we had 2-5 percent would be much easier. But these 10, or even 15+ are scary. Just look at this weeks difficulty it's scary high. I think group 3 is pretty small. Most that run at a loss I think sell gear at this point. There is not a whole lot of reason to run at a loss. They might lose a little before figuring it out. There are some that claim they support BTC no mater what, and want decentralization. But most can not afford this luxury of losing money on a lot of gear. BitFury has a new miner proposal to put 2MW miners into a container sized area. It is 12-16 PH each. So there will be no place for hobby miners in the future. They have a rendering of it, that is far from having it. You can make a rendering of almost anything. But most of the big buyers I am guessing still have a data center set up. Chances are they will not need to invest in this container, they will just need to swap old gear to new gear. I don't see this container being a big seller. When SP 30ish gear was new a company made containers and I think they got like 2 as proof of concept, but sales never caught on. |

Is there any spot for Hero member? ( I'm currently senior member but in few days i become a hero member ) can i join this campaign?
Was answered a few posts back... a page back.. first page, etc Will you open the enrollment for new members any time soon?
In the near future, there are no plans to open enrollment to everyone. |

If you only want to spend and not trade the bitcoins, you can try this website: www.bitcoinstore.com/The website has mentioned all the websites that accept bitcoin payments and I feel this is the best way you can spend the coins wisely but if you prefer buying gift cards for 80%, you can save even more. Watch out on gift cards sadly there is a lot of carded ones on the online space. Yes they are cheaper... but if you get a carded one depending on what service or store it can hurt your account. For example if you use carded iTunes, they can ban your iTunes account. This is why a lot who buy giftcards ask for picture of receipt showing paid cash for gift card and not credit card. |

you can wait grow up your account rank or you can buy minumum full member rank bitcointalk account and join one of the signature campaign.
yeah probably the OP had already owned a high ranking account now...  and might be in a signature campaign...other than what I mention, he could also sell his skills here and be paid in bitcoin. I suggest you grow your own account. If you buy an account there is a decent chance it was farmed and posts are utter crap, we all have seen them ones with like what was your last drink, what was last music you listened to... just a ton of offtopic. These will not get you into any decent sig campaign. If you raise it you not only learn knowlege along the way. You have a account with better post history (in my opinion). And someone is not going to possibly get it back. On a acccount you buy it could be a account seller claims as stolen with being able to sign with old bitcoin address, they can get it back. I am very much against bought accounts. Think twice before buying one. |

trying to make a PAPER WALLET (so called hard wallet/cold wallet),
using BLOCKCHAIN, I have some insecurenesses
on that print are visible: THE KEYS
- the public key: my bitcoinadres, receiving btc's
- the private key: this key is for sending btc's
this is a part of the paper wallet, am I right so far? YES/NO?
greetz, peter (the netherlands, now here it is almost 09.30 in the morning
Yeah, thats correct! Did you create your paper wallet offline on a secure computer? If your talking about paper wallet from blockchain.info that is not a cold wallet. Yes you have a paper wallet but it's from a hot wallet.... so it is not cold. Did you use blockchain.info? That is how I'm reading it if so you did not make a cold wallet. |

In my opinion, the best bitcoin wallet is blockchain.info.
It is easy to use.
Same here. i'm also using blockchain.info for online bitcoin wallet. Easy to use, simple, no adds and the fee also small. the only problem for me is the confirmation is sometimes to long. Just make sure you keep in mind it's a hot wallet. There are uses no doubt for a hot wallet, but it should be treated as such. If long term storage there are likely better solutions for you then hot wallet. |

So I'm new to mining and I've really been enjoying getting into bitcoins and whatnot. Purchased my first s7 a couple weeks ago and have 2 more in the mail.
I went purchase another 5 today (I can run 8 with much electrical modifications in the basement) and the website has changed.
Batch 9 has been removed, batch 8 is still for sale but unavailable (can't put it into cart and wire the money). Batch 10 was added to the website about $150 cheaper than the batch 8.
The product description for the 8 says it's the last stable build, this along with the lower price of 10 leads me to believe that 10 is inferior somehow. Was does "stable" mean in this context? Should I possibly look to buy 5 more from eBay or Amazon (or another source)?
Two final questions, I ordered 2 noctua fans to try and reduce noise levels, anyone else have success doing this?
And finally I've been using slushes pool. Do people generally favor other pools or are they all similar?
Thanks!
On changing fan's out it will be quieter, but if you do it you void warranty. So if caught you have no warranty if there is a problem. May seem little thing, but you cant do anything really without permission anymore with them. Chances are Ebay and Amazon are a decent amount higher then batch 10. So it's really your own call if you can wait till batch 10 it is a decent amount cheaper then resellers I'm guessing. Ebay you might get a deal all depends. |

Racing along now at 70C, starting to drop (slowly) as night comes on. Ok for mild summer, and def ok for winter but when 40C+ hits...the poor little miner's fkk'd. Thinking I'm going to have to ditch the box as a bad idea, get a set of wire shelves and work out a different security option. (Wire cable to the shelves perhaps  ) Thanks for your advice guys, Crash If at all possible I would look at inside your house still. You might need to underclock or something to make it bearable to you. But I'm not huge fan of under house after thinking about it. Do you get rain under your house? Just thinking of environment and setup under house could be hard. Securing all depends on you honestly. I know my miners have a alarm system, and cameras. Is that overkill for most? Yes chances are it is. But mine is above a garage/crop farm work area. So it is really to protect both. Oh yes, the boss has def made it clear that inside is unacceptable. I have a garage that I may make use of in the future, it is just too far away from the house for a feasible internet connection. (and so full of cr*p that there's no space). Underhouse is waterproof, but exposed to atmospheric conditions; i.e. humidity, wind, dust  Which is why I went the server cabinet (box) option. Advantage for me for underhouse is easy access to internet and power. As an experiment, and starting point, the location is what the location is; i.e. in the future I may set up in the garage, but as it is about to be demolished, I'm not running power or internet out there. The property is secure, but bad people can always get over fences. Admittedly US$500 is not a big issue for me, but I'd still not loose the miner to theft. Crash And your box may be great for short term. I just think when you hit the hot day's of summer with so little of fan's its going to heat up and be a pretty harsh condition. And elements from outside is kinda a pain. I'm not sure on your electricity prices. But if your in the market where S5 level miners are still profitable in future maybe look at Avalon 4.1's. They are not a huge difference on efficiency I think high 50's instead of low 50's if I remember right. But they run so quiet underclocked they are the most quiet miners I have used (not including like USB sticks, or old blades, etc just modern miners). So a big difference from the hot/loud of the S5. But again that all depends on your electricity price if they even make sense at this point. So the box has failed. Went to work today, came home and the S5 is at 74C  (Still working, but unacceptable). Grabbed a cheap Wi-Fi extender and switch, and moved the S5 to the garage: http://imgur.com/7eIRFozLate in the day now, still day time though and warm at 25C, and the s5 is plugging along at 58C Cheers and thanks everyone. Crash Yea that is hotter then i would like it. I think you made a smart move taking it out of box. Likely will take more CFM's from box fan or something big I think for box idea to work. Glad it worked out in garage. Looks like much better setup then the box. |

As written above: Do not connect more than one PSU to the same hashing board! In the rest you can fool around as much as you like for s7: 2miners on 1 psu 1miner on 1 psu 1600watt 1miner on 2 psu, one above 1.1k and the other 600watt 1miner on 3 psu, all 600watt It also depends on the batch of the s7. On first batches the evga 1300w is good enough! That is the problem is it is going to void warranty which is a shame in a lot of cases. Two 750's are mentioned so 1 is not going to be able to power 2 hashing boards. So it would be mixed and voiding warranty. I thinks it kinda get's into a mess connecting multiple. If it's in your budget I would get a decent server PSU, and use it. Chances are I don't see bitmain moving away from 10 PCIe, as it has made them money selling PSU's. So you likely will be able to use these server PSU's more then 1 generation still. And if not can always sell after. |

Hi, I saw information about S3 antminer, I'm looking how to configure your computer to connect via a TCP / UDP port. But configure the firewall, and router with the same ports and addresses and ports remain blocked.
If do you have any information for configuration for the firewall o network.
Any suggestions accepted.
It would depend a lot on what firewall your using. Most I'm guessing are the ones included with router chances are as far as hardware. I'm not sure about " I'm looking how to configure your computer to connect via a TCP / UDP port. But configure the firewall, and router with the same ports and addresses and ports remain blocked" If you block something ... not sure how your getting through. You might look into things such as whiteistiing IP's if you know where your connecting from. But the most easy way to remotely connect I recommend for most is though teamviewer. |

With the difficulty sky rocketing not sure there are many good options for the small-time miner. I guess if you just want to buy some miners and not worry too much about profit now would be a pretty good time to buy with the price so low. Probably have another 2 months at least before we see new miners, and their price will probably be high. Of course with upgraded efficiency and the halving .25J/GH is not going to cut it after that.
I agree. Ya gotta start somwehere. Back in early 2014 my total initial out-of-pocket was ~$8k. Four thousand of that was wasted for most of the year due the AMT/Bitmine.ch scam, the rest went to Ants. For the most part all BTC earned was re-invested in expanding the pharm/new miners replacing old. I'm now up to 70TH/s with all miners (and the original investment paid back) paid for by BTC earned with a nice kitty left over. It takes time and patience but unless the impending halving hits harder than expected I think it will still pay off to start now. Are you running 70TH in your own mining area or is it being hosted? And I would agree it's a slow ride anymore. I remember when it was a quick 3 month ROI. But no longer is quick and ROI mentioned together. Patience and being able to hold long term I think are two important things. I like to pay off electricity out of it and hold the rest. Will see long term how I end up on my investments. |
