Can you get me a screenshot of the miner status tab? Are you solo mining? Basically if you're in a proper pool, you should be getting accepted shares. A couples per minutes. Give me more information  |

Thank you, those cables look nifty, i will try to get a few. Basically it would be pretty nice for chaining S5's for now, just need to get more boards and then later on i would already have them handy for S7s. |

I am also interested in those long S5 18 pin cables, do you have an open price per with shipping estimate? I guess i'll send you a PM with my information shortly.

i know you said good condition, but imma leave this here for you to consider..
i have an s5 with some issues.. im not sure exactly whats wrong with it, but i do know one of the hashing boards is totally fine, and the controller board was recently replaced by bitmain.. i could sell it to you on the cheap & low if your interested..
Sure well you can give me more information, i'm not sure about forking over too much money for such unit for i'm listening. Or if you have a thread where you're already talking about it. That would work too. Information such as, whats going on with the miner, what PCB version the 2 PCB are, how does it behave, why is one of the board dead, etc. Such information would be needed. all i can tell you is that i got the miner from someone here on the forum and within 3 days it began to malfunction.. for what reason i do not know, but it would go down to 0 hashrate for 1 board with (------) in miner config for that board.. it would stay accessible via LAN.. eventually, however, (as in the next day hehe) the 2nd board would also hash down to 0 and the miner would be on, but not mining at all.. it would start mining whenever it was rebooted or reset in any way, but eventually go back to 0 within 15 min or so.. i sent the controller/hashing boards to bitmain, and i know they replaced the controller one.. i dont know what they did to the hashing boards, but they are basically the same as before.. i reassembled it, but tbh pretty badly at that.. i would take $100 including shipping if that works for you edit: i forgot to mention ... it does mine now at half capacity.. consistently Sure, can you get on IRC or Skype or something? I got a few more questions but half one is a bit like of a S3++ so i'm interested. Lets take it to PM. |

Pretty sure BRAZIL should be the leader if the taxes weren soo high as 50% more of product value,reaching sometimes 100% ,why im saying those because energy painels where else is soo many sun all days? But China is leading with the big miners presence being there.
But solar energy ain't that cheap, the battery for a year for a kWh is about 400$ too. Then the infrastructure, the panels, the people that need to maintain it... Its not a 24/7 things. You can use solar panel to cut down on usage during the day but to run around the clock you need energy storage and that doesn't work well in costs. |

No not yet.Given the slow speed at which people are adopting bitcoin in my country,I doubt if I can buy anything with bitcoin in next 5 years
Why? Debit cards don't exist in your country? You can get an international BTC Debit card and it work as long as your stores accept debit/interact. And then you can use BTC all over the world with online sellers. |

The only one CURRENTLY selling miners that are viable for home miners *RIGHT NOW* is Bitmain.
There has been at least one other "soon" announcement, out of Lktec, for a miner that the S7 appears to have been specifically designed to try to preempt.
Since the Lktec design appears likely to be based on the "announced as taped out" Innosilicon A3 design, and since Innosilicon has made miners in the past, I expect a fairly good probability of an Innosilicon miner design as well - but even if they do that, I suspect that that Innosilicon's miner would be more along the lines of a rack-mount 4-5U unit in the 20-30TH range, similar to what they did on their A2 Terminator design.
Too bad Spondoolies has abandoned the consumer market, perhaps they'd be willing to start selling their new chip *soon* to someone like Sidehack to build an actual HOME miner design out of.
Well Bitmain "Right now" has nothing. It's true there will certainly be a second batch in October but it's pretty moot right now. Meanwhile Spoondoolies is Selling those SP50, however only in Bulk. Now what qualify a "Bulk" i don't know, but that mean a reseller could get a batch and then sell it to end user. But there's some serious issues with powering 6000W at home. Noise and heat will make this pretty prohibitive, so even if the home buyer can get a hand on a SP50, it feel like you'd need a crane to move the damn thing around. Meanwhile Bitfury announce something even better but with no actually hardware available. At least Bitmain is getting some pressure so we might be seeing S7's at reasonable ROI soon. Then again that's pretty subjective if these 3 company sell 150PH of hardware by the halving, there won't be much current miner left after that. 6000w? It's 16500w AFAIK Yes, i was missing a 1, there. Effective Hash Rate 110 TH/s ± 10% Nominal Power Consumption 16,570 W Depending on how many they made for their first batch, it could equate to a fairly big difficulty bump. Though of course nothing will happen this weekend. |

Up front, I'm a newbie using a used Antminer S5. I got everything set up and working, and the thing is hashing at around 1.1 - 1.2 even though it's slightly under clocked. I replaced the main fan with two quieter fans, and even in my office I can keep it around 74 degrees. I've flashed it with the latest OS, (fan control update) and have it on a brand new 850 watt power supply. THe fact that it's used caused me some concern, but the things seems to be running very well.
The thing is, I've never seen the green light! Right now it's humming along nicely but the red light is flashing 1 second on, and 1 second off. I've searched, pretty extensively, but can't seem to find out what this is indicating. Any suggestions would be very helpful.
Here is the relevant thread; https://bitcointalk.org/index.php?topic=902305.5460Basically it work just fine with the common issue. It arise after you flash the fan control firmware. I do not have that issue, but it is a common issue. So maybe its a PCB version thing. Also, there is no green light. Beside the ones on the boards. |

I can tell you what i gleaned from BTC in Brazil. I have a friend in Brazil and we wanted to exchange money using BTC. Legally, BTC is not widely used in Brazil because there is a huge seller tax on it, like pretty much everything there.
So i can understand why they would avoid dealing it there, since having to pay 20$ on the BTC as tax when converting currency is ridiculous. So what Brazilians do is participate on USD/BTC exchange by using a USD account.

well do you know if genesis mining is legit?
I would probably stick to Hashnest since that's Bitmain's if you really want to help a 3rd party make money. Cloud mining by default mean you're helping someone make money over you making money yourself. If you want to make money but not have your miner at home, look at miner hosting service. The maintenance fee in Cloud mining services are way too high and you'll generally barely break even and then make marginal profit, if you're lucky. |

I was watching a video for coinbase.
It seemed like when you sell bitcoin to USD, that it instantly goes to your bank?
Is there any wallet that will let me convert/sell bitcoin to USD then leave it in the wallet in USD?
I also need to be able to register and do this without a bank account. I plan to open a new bank account this week, but I would like to gegt the bitcoin sent to me ASAP and have it sit in my wallet as USD until the bank account is open and ready for transfer.
Coinbase actually let me select To CAD wallet for me. So i'm pretty sure Americans can pick To USD wallet. Just keep in mind, not all online wallet services have your money guaranteed in case of hack or other event. |

I have been experimenting with different fees myself so I get some real life experience and not some theoretical calculation. It seems I don't see many differences between 0.001 and 0.0001... it takes more or less the same for some reason. 0 fees is horrible tho, always pay the default fee is my advice.
Why would anyone pay 1BTC of fee tho?
How much has been the maximum delay (according to your experiments) for a 0 fees transaction? Just curious It really depends on the transaction backlog at the time. During a spam attack it most likely just wont. If not it can take weeks if its a small transaction as its age raise. But it can also take a few blocks. You can check on the blockchain.info of a transaction to see whats its current priority. It will also tell you warning if the fee is under the recommended level at the time, etc. |

In my opinion, although the largest proportion of the mining hash-power is from China, the largest number of individual miners might be from the United States of America. In China, they mostly have giant-sized farms employing thousands of rigs, compared to more medium-sized and individually-run mining farms in the United States.
Which is kind of Ironic, considering the very bad average electricity cost from Americans. But you can see with the node spread graphic map that there is a lot of activity in North America, and most of those places have high electricity cost. Sound like a lot of American are making poor investments just because of how awesome BTC is~ |

Thanx for the info. So i'm not he only one.  But in the same spirit, its not happening to me, so it sound weird, and i also manually updated to the fan control version. Maybe its a board version thing? Mine is v1.91. |

You can use a conservative figure for difficulty, but you must also not forget the Bitcoin Halving in 2016. You don't even get close to ROI'ing the S7 at 0.1 and considering how overpriced the S7 in Batch 1 was..
I kinda doubt you'd be able to resell it for a similar value in 2 months... especially with the competition arising.

As it says on the subject, which is the max temperature recommendable for an AntMiner S5?
I have 16 AntMiner S5 works 24 hrs/ 7 days. The max temperature registered has been 66 Celcius in two miners (often the hotter), is it bad? Rest of the day is about 57-62 Celcius and the night is about 57-59 Celcius.
Well, 70. More than that can somewhat shorten the life of the S5, which is probably plenty long anyways, the risk is more burning something off. Under 60 is recommended for longer life time, under 70 for best stability. If you want to get the temp down and the noise down, i recommend you use a box fan to blow air through it, through the fins too. My S5 is currently at 48C with fan at 35% with ambient temp at 18c. So +20c and its pretty quiet. |

Just use whatever's cheapest. I just use a hub and plug the cheapest cable everywhere. 1mbit, 10mbit, 100mbit, 1000mbit, it doesn't matter. My 20 miners + personal PC, chat and everything is ~ 30kB/s total.
For something a bit more explicit. I have 7 Antminer S1 on wlan, and my wlan usage at the moment is average 800bytes per second. The windows GPU rig that also run USB stick seem to take more, 3kB/s. Bloaty windows 8 Services.

Worst case scenario and it's got problem at lower voltages, I end up with a nice high current supply for testing car audio gear I repair. Have to definitely consider this unit.
Well as reported you might be able to go down to 11.5v. Unless something weird happens and you get results that we've only been able to repeat on v1.91. But if not, its not like it can't be used as a "Normal PSU" as well, since it work just fine at 12v. The efficiency isint too bad so, why not. |

Thanks everyone. I got it all working fine. Found some youtube videos to make sure the cable were connected right. As far as the cables being hot. I just checked. They are warm, but not hot. I spread the miner from the PSU because I thought the warmth could just be coming from the miner. The hashing rate is good so I think it's all good. Thanks again! Good luck with that S5. The best solution for the heat and noise i found was to use a big box fan and have air block through the fins by putting the miner sideway. This would also cool the wires so 2 bird one stone. |
