home mining is already a myth if you don't have the same electricity as there is in those big farm
those farms can sustain the halving, so with the same bills cost you would also
The only thing is we have no idea what difficulty and value will be around having. We have had a decent jump from 230 or so for longest time to current 450. So we are experiencing a jump up in value. One thing I need to know is value at having. It is true these mega farms have every single advantage. But I hope home miners with decent electricity can keep mining, I will do it until it's not feasible. For the mega farm to have every advantage they need to have a way to use the heat. Many big farms have an issue with heat they treat it as a waste product. They are making so much they have a luxory as using it as waste. They so far have not had to use heat for anything, and they remain profitable. I don't think any of the mega farms will be switching over to using the heat anytime soon. But I could be wrong on that. |

Oh cmmon people, it s Xmas, dont delay payment today.
I tend to agree chances of him being with family and not having time to fix it is high right now. I would cut him a break with the season. There sometimes is a hiccup or something goes wrong, but in the end the payment has always been paid. So I would not be to worried. I think the hot wallet ran out and has been refilled so should stop future problems. But if you have a payment issue just send a PM to macro, and I have a feeling after Christmas it will be fixed up. |

This is my third antminers7, and it all of a sudden stopped hashing. At this point i can't connect to the configuration page, and the four led on the controller board are lit except the D1 light which is blinking. I have tried the reset button and multiple hard resets but still nothing.
Any ideas?
The basic things to check are - Power down the unit and unplug all PCIE Cables and leave them unplugged for a minute or two, during this time check all connections on the miner to make sure nothing is loose
- Check PCIE Cables and make sure they are seated properly and not plugged in backwards (I've seen someone do this and somehow the miner still powered on). It worked fine after the cables were connected properly. DO NOT HOT SWAP PCIE CABLES
- Contact Bitmain for warranty support if still in support period
Hope this helps, good luck! The hot swap is a big deal. OP did you try any updates? Or move around any cables? Or did this just happen with nothing new added to situation? |

Got the official response back on efficiency: "Currently, S7 is fixed with frequency to make sure the hash rate is more stable. but the voltage can be adjusted. The power consumption is 0.25 J/GH + 10% as marked in website."
So it appears the 4.7 is constant. And that efficiency is the +10 marked in specs.
They say the voltage can be adjusted? That make it sound like the software control is back in. But what do they "actually" mean, since we know they blatantly mislead with whatever they say? That you can undervolt it at the PSU level? As long as this is referring to batch 8 perhaps they just got voltage & frequency the wrong way round? However might imply that in the future Voltage will be adjustable? Rich Yes should be batch 8 I asked specifically about it. They apologized about how long it took. But said one of the engineers was consulted to get a anwser. So it should be petty valid info. Yes but we know that batch 8 , as are all batches, is frequency adjustable and that it is not psu adjustable at the PSU level because of the buck converter.. so.... they must have made a mistake and the only half sensible explanation is that they meant that " currently it is fixed voltage but the frequency can be adjusted"? Implying that at some point in the future it will be voltage adjustable? Or... have I been drinking too much as it's Xmas Eve? Rich What I got out of it and I could be wrong this is my opinion. They have it where it get's 4.7TH they seem to not have any issues with being to far off that I have seen. So they kinda locked it down to where you get what is advertised. It seems like they are keeping design longer then others it seems. We know for sure batch 9 will use the same, and it could be possibly longer. |

Trezor the prices are still beyond my reach, in fact the price is not expensive, because Trezor indeed in a very safe design and trendy, appropriate once at that price, elegant appearance clad in comfort, perfect. I hope someday to be able to get it.
It is one that is not to expensive is the nice thing. I think it all depends on how much you have to store. Even 1 BTC currently this is less then 1/4 of your value in btc, that you lose if compromised. As your BTC holdings grow the more it really makes sense to look into the hardware area. You will not regret it if you do get one. |

Everyone who currently has bitcoin is an early adopter, because in 5-10 years bitcoin will skyrocket!
I don't know that now will be looked at as early adoption. I think it's jumping in much later then early adopters. Early adopters had no idea how much, if anything BTC would be worth. I mean look at the first purchase of a pizza.... that is early adopter. Now we know BTC has a value (a lot higher then back then), so we are still adopters but not early I don't think. You never know $1 million in 10 years would make $400 look like free Do you honestly believe 1 million in 10 years from 450? I think that is pretty unrealistic myself... I expect it to go up but my speculation is much less than 1 million in 10 years... that just is not a value I think people will pay for 1 BTC in that time frame but I hope I'm wrong. |

Do not spend it, save it. unless you are using what you make to live, there is no reason for you to spend it at this point. Save it and wait for the BTC to go up. When it goes up, you will be glad you did this. I know I will be.
Saving all of it to a point I think. Everything in moderation is good. I personally like to pay electricity out of it. This keeps me where I don't spend a small fortune per year on electricity. If I spend regular earning on electricity, and it goes down and I paid electricity with my regular earnings... I could lose a lot. So I view electricity payment as responsible. And then I keep the profit and ROI. It has been a pretty good system and has worked for me pretty well. |

They give some "profit" illusion to drag you down into their fake mine.
That's why you should more carefull or you will regret forever
You can't group 100 percent into this category. Sadly yes many scum have created ponzi schemes, this is why people need to research. Look at hashnest do you think it is fake mining? I honestly think it is mining and not fake, and I get 0 dollars for saying that. So there are some good.... but sadly a lot bad. |

I want to create a few paper wallets to give small amounts of Bitcoin away for Christmas.
I am wondering whether those paper wallet generators are really secure. The site owner could store the generated keys, couldn't it?
Consider to create the wallets on bitaddress.org
yep they are definitely secure. i actually prefer them over web wallets, because thers no way someone can hack your private keys if its printed on a piece of paper. also when you create the wallets i recommend that you download the html and turn off your internet connection before creating wallets just to be extra safe. Above it kinda got a little off with user putting up false info about hardware wallets. I am a supporter of hardware wallets at this point as they are hard to screw up, and keeping key off computer and signing on device is huge benefit. And you still get the power of storing seed words in a safety deposit box if recovery is ever needed. Paper wallets can be very safe if made and used right. If you have a system that is not compromised and the dumber the better on printer, it can be very secure. I went to extremes on mine by installing OS, anti-virus, and anti-malware do the paper wallet ... and then blow away OS. Some will say it's to much but made me feel safer. If you do use paper wallets having multiple is not a bad idea. This way if you need to spend it you don't enter a private key from paper spend a little.. and then still have a bunch of BTC on that paper wallet. I see that as most likely greatest weakness is when you import it back to spend it, as it's now been on computer. If your going to use paper wallets you might create a few with nothing on them. So if you use a paper wallet and import it on PC just incase compromise you can send it to wallet that has not been imported. I think what you do after importing wallet has a decent effect on future security. |

Much as I agree with not upgrading firmware without good reason.... You are very unlucky to get a failure. I have an S5 Controller here that I play with and have probably upgraded 20 or 30 times without problem, this includes loading all of the different S7 firmware versions onto it to have a quick look at what was in them.
You should be able to recover from the SD card with an image or if that fails you can connect a Terminal, although this requires taking off the BBB and soldering some connection pins and having a 3V TTL to USB converter.
Rich
Thanks for the suggestion, I have a 3v TTL to USB converter but no solder unfort. I do have an SD card however, will try just dropping the contents of the upgrade tar.gz onto a fat32 partition but in case that doesn't work do you have any advice on how to proceed? Thanks You might contact bitmain. I'm not sure if they have the ability/or what it takes. But on S3's they would send out info to un-brick a S3 via serial/usb. I would at least ask them as it does not hurt. I have not seen anyone mention this so not sure what their official response is. Also if in warranty defintally contact them as they will fix it, but downside is you lose day's of mining compared to fixing it yourself. |

Hey, One miner not means mining rig... Are you planning rig or example Antminer S7? (Buy 5 - 10 Antminer S7) + power supplys all? What you do with Raspberry2  Its better bitcoin node/full node... - It has not enough power to mining, maybe a small scale... http://raspnode.com/diy.htmlOkay, fair enough. So it's not a mining "rig", it just has 3 USB ASIC miners. Yes, instead of plugging them into my PC with Windows, it's plugged in to a Linux computer (Raspberry Pi). I know this is small scale, however, I'm just curious as to whether or not I can plug a different miner (The Antminer U3) into the USB Hub and have CGMiner auto-detect it? Well you might be able to auto detect, but what I do when using different types is specify usb's in command line. If you plug in all the asic miners then do "sudo ./cgminer --ndevs" I think it is shows the location to point --usb at. Get one instance running and use that. Then plug in different usb and do same thing and specify it on another build of cgminer. So you will have 2 instances of cgminer running. (Also means you install it twice in different folders is easiest) |

Im thinking of purchasing a few more BitMain Antminer's (S5 specifically), currently only have one S3. When running multiple miners on a solo pool is there anything special I need to do? Do I just plug it up to my router and they work together automatically or is there more too it than that?
Yes I am rather new too mining but I am decently tech savvy.
Thanks in advance!
With buying only thing you might need to do is change network info along with the pool info others mentioned. It varies greatly how sellers do it on selling gear with used. I always included a piece of paper with IP address to make buyer's life easy and mine easy as less support when installed. But if good seller they will either set it on DHCP, or they will send with static IP and tell you it. If you have to reset them then it chances are will need to be 1 by 1 and set to different IP's. |

Glad to hear you success Searing! I truly believe Winter mining and Summer mining are different beast's that's why on my gear reviews on all new one's i've been putting it in the title.
Summer I had to use a lot of CFM's. But with winter I can slow down fan's quite a bit and the free cool air helps out and reduces overall costs. So winter is easier season to mine in.

Thanks for sharing! It's great to see a pod. Exciting to hear the future of these. I like the idea of more chips on a board and going from 1 to 8 definitely does that.
Have a Merry Christmas aswell!

I buy ALL my stuff from Yoshi in Bitmain Denver.
NEVER have a problem with customs. He imports, you get your miner shipped from Denver. For about 1 1/2 years now. Excellent customer service.
Does he charge standard list price for the miners, or sell at a slight premium? Standard list, wire or BTC. You pay premium if you want USA warranty and/or pay with PAYAL USD. I use AMEX through PAYPAL usually. $100 per miner with USA warranty. Worth every penny. Just sidestepping the customs headaches is a blessing. Just had a batch one replaced, only down 6 days, one or two days was me trying to fix. Where could I contact him?. To buy a miner. Removed info If you are able to order from there please let us know. I know Wolfen has said he get's from there. I could have missed it but I sure have not seen a big jump of people saying they are able to order direct from US. For the rest it's been website or possibly email if really big sale. But I can't imagine if you buy a few US doing the selling but I could be wrong. |

Thanks for sharing, I don't mind a shameless plug when it benefits something good such as this and compac making.
Really neat to see 49 mining at once on a single hub. Do you have a screenshot of it on PC would love to see pc screenshot with 49 of them running?

There is something about Innosilicon that doesn't quite make sense. Why go public and push the A4 chip when LTC mining is a much smaller market. Really what is the future of LTC?
I agree that the A4 makes no sense at all. They probably decided to make it when litecoin had a little pump a while back to 6$ or so. Bet they regret that, now. They're making the A3 also, though, right? That's their new SHA256 chip. I really hope they and their partners come out swinging at bitmain. They said they were making both which does seem kinda crazy to R/D 2 chip's at the same time. They were HUGE on selling A1 chips, if they are as good with A3's they could be a decent force. Also something unique is they tend to sell chips so we could see multiple companies sell A3 machines if they stick with old model of sell. I have kinda lost a little hope as they announced it so long ago. Just seems like it's been quite a while. But I hope they do make it even though they seem to be pretty quiet. This might also indicate that for a chip house like Innosilicon, to get to first mining chip prototype, costs <$100k? It's hard to say on cost with being a private company we will never know this most likely. Chip making is pretty secret, I'm surprised they mentioned it so early. I imagine they are pretty busy if truly doing 2 chips at once. I think A3 will be main focus and released before A4, but that is speculation. They made a lot of money from early on so it's hard to say what their budget is on chip R/D. |

SHA256 altcoins are rarely worth mining for themselves, the very low value and relative difficulty of getting them traded into something usefull usually more than makes up for the ease of mining them.
non-SHA256 altcoins vary - LiteCoin and DASH have been viable alternatives with noticeably more stability over the last half year vs. BitCoin, though it looks like the SCRYPT altcoin mining ecosystem is a few months away from it's first major shakeup since the Litecoin halfing (and possibly it's biggest shakeup since the GC3355 was introduced).
DASH is profitable to mine with a well-tuned GPU rig, though the ROI timeframe makes it somewhat iffy if your vid cards will last long enough to make RoI.
I would agree I was decent into alt coin's during GPU day's and during first asic day's of them. But at a point they really switched to a LOT of pump/dump and a lot are scrypt which BTC sha mining gear will just not ever mine. The second one worth mining is LTC really and it's scrypt. But a lot of altcoins even scrypt are utter crude. Just nothing but a change of name/picture and promises of a bright future. I think BTC will remain king as far as mining. You will see it's what the manufactures focus new gear on for the most part. And they do it as most return in in straight BTC in current market. |

the next miner will be S7+ version ,something like 10 Th/S and about 2200 W
Depends on competition I think a S7+ is not to hard to believe since S5+. But S5+ was a very short lived batch, I love mine still. But most did not order one. Also it's a really quick way to get rid of old gen chips. So if they move on a batch of S7+ before going to S9 makes sense. How long till this? Who knows at least over a month as we know Batch 9 is being made up till around then. I hope we get a while on current gen before next... but your never know. |
