Have you done the ROI math? I really think you should if you are thinking about profit. If you are doing lotto mining (trying to hit a block) then a usb miner like compac does well. I could be wrong but I don't think you have done ROI math to this. I may want to start a little project to make little bitcoin farm, which is hopefully profitable. I want to use usb miners. ....
Sorry, but what is lotto mining? Lotto in my country means like a you buy a ticket and can win a lotterij. Is that same in english? Lotto is mining trying to hit a block by yourself. Normal mining you use a pool and a bunch combine power. Lotto you are trying to (in most cases) solo mine a block. Chances are you never will hit it so it's like playing lottery. Usb miners will not be profitable pool miner, just to high of cost per GH. They are fun though and great lotto miners. If you truly want a profit you need to do some ROI math and look at bigger miners. The day's of pool mining with a stick miner are over. If u talk about big miners, do you mean like asics? I hear alot of people using an s5mto mine and get a good profit. Is that possible with my electricity cost? I mean bigger asic miners yes. A usb stick miner costs where it's a good lotto miner, but you will not make a profit from pool mining. Your electricity is just to high 0.22€ per kWh over time stands little chance of ROI. Likely you would lose a good amount of mine running miners (might be a little better with surge in price). But still no one should home mine with electricity prices like that. You could look into hosting somewhere else that does not have the very high electricity price. |

do NOT give this person any of your BTC. If mining themselves wasn't profitable, selling mining power to others would not be profitable for them, simple economics here.
Sorry you are wong... why are you wrong? because you have not read or not understood what I wrote. you talk about BTC...I talk about satoshi lost satoshi if you do reach not the minimum payout or if you reach it you have huge fees. Then...please do not misinform people here with things you do not understand about. Have a nice day. If you do a "mining team" you likely would need to somehow escrow it where a very trusted escrow got the money, and not you. It is nothing personal just when you have "Warning: Trade with extreme caution!" beside name no one trusts you. So if you want to do your idea get escrow for or else you likely will receive the same response you got above a lot. |

I Have a question: If i would buy from Sweden five Antminer S7. How much VAT would be added later on when it gets shipped? Say it cost 1799:- each Times five = 8995:- + VAT? =  Customs "tull" In Sweden would then i presume add the value added tax and bill me within a month i guess... Anyone that has Experience with Buying form Bitmain before and can fill me in on this issue? Also if i add a Company VAT number with my friends company. Would they Discard the VAT totally? or just bill the company? . Heard different things from different sources One more thing; looked at one alternative site that ships within the EU, Called http://www.antminerdistribution.com/ . How reliable is that company? if even at all? they claim to Sell S7 overpriced in EUR with VAT included Antminer S7 – 4.86 TH/S – Batch 5 €1.914,- VAT excl./€2.316,- VAT incl.. How can one know if this is true? They ship it out with correct value on it. If you have a vat yes you will be charged a vat. They will bill you not bitmain on the vat. If you use a friends company vat number like you suggested you would be breaking the law I'm guessing of your country. I would not personally go into breaking laws to save from vat. |

Hello all. I've seen this question asked over a year ago https://bitcointalk.org/index.php?topic=914006.0 and was hoping that there is a newer solution to this question. I'm looking to buy a miner and want to know what miner can I run in my home-office that will be quite? It needs to run on 110 volt as I"m in the US. A friend is running a SP20 down-clocked to 1.3 and it is still a bit loud. I'm running two Rockminer R-box 100's. They are quite by not producing much. Thank you in advanced for your recommendations. SP20 is not really a quiet miner. Avalon 4.1 is most quiet factory made and you can down clock it a lot, but it's a little higher priced miner the say S5. Some run S5's on lower freq and do fan mod's. It really depends on if you are willing to mod. Phil has a thread on making S7's quiet. So really all depends. |

Wow 3.8BTC for the next batch now. Crazy.
Those who paid 8 BTC or heck even my S7 I paid 5.8BTC for that shoud arrive tomorrow costs too much!
How high is BTC gonna go on this run? Some people may get some sweet deals on S7s but its going to screw the early guys that's for sure!
how does it screw me when i insta-bought BTC to pay for the miner (or used coinbase USD wallet, which is essentially the same). I essentially paid $$ for it (same price then as now) plus will enjoy ~2 extra months of mining, hopefully. It is for those holding BTC and buying with BTC instead of holding. If you spend USD (or get BTC instant to pay for something) I could see how it is a different investment. But if hold BTC and paid at 230 and now it's 490ish you would have been better just holding. So I think it depends on if you paid with a stockpile of coin or via usd/instant BTC for miner. |

On BTC I judge profit on if I get more BTC then I started with. I do not judge in value of BTC as that would skew the results and possibly show ROI when you lost btc (unless paid in USD).
The difficulty could be quite high if it keeps going up. The good news is there is only so many miners they can make, and so many data centers without building more. I don't think anyone can give you a good speculation on what will happen on it.
So it is too late to start mining right now? But how can no one know what the difficulty will be? Did Satoshi make it go random or something? It all depends on your personal factors. For example what is your electricity? And do you have a vat/income tax? Not one size fit's all. But no for a lot right now it's not to late to start mining. But if you have high electricity price... it's not that your to late but that your factor do not allow mining. My electricity costs 20 cents per kWh I believe, but mayby I can run it on the college and I not have to pay any electric bills. Do usb miners make a hard sound? Do they need to be ventilated? USB miners can get quite hot easily as they are still miners and can generate huge amount of heat. You will surely need a fan to cool them or at least a large heat sink on the chip. If you get good quality fan, you can reduce the sound. I personally like arctic breeze USB fans. It depends highly on the Freq and power going to the usb stick. Have you used any modern USB sticks? Mainly the compac it's pretty much best one to go with. But you don't always need fan. Depends on freq and power, you can make it go high where you need fan. Or let it run low and it does not need a fan. So it really does very of if it's needed. |

So here's another mystery to add to the U3 story. I've been running 1 U3 for several weeks now and it has been behaving "normally". Today I turned my S3+ back on and, for no other apparent reason, the U3 now runs at a 13%-15% error rate. If I turn off the S3+ the errors drop back down to "normal" (for this unit normal HW error is ~ 3%). They are both powered by the same PSU (800W gold rated, plenty of juice for them both), but that is the only common thread. Isn't that peculiar? Anyone else had a similar experience?
Kind of similar, have 2 U3's (had some more, but they died) running along with a S3+ on a 1000W EVGA. Was getting zombies like normal with both U3's on same pcie, put each U3 on it's own pcie and haven't had a zombie after more than 48 hours (YET). They have reset from au3 0 and au3 1 to au3 5 and au3 6, but there still going without me unplugging and replugging. Also for 48 hrs I've got 531HW total right now, where I would be expecting ~ 3-4 times that many in 48 hrs. So I'm wondering if bitman either: A) way under estimated the power requirements for the U3's or B) used some really cheap power component, that it takes the power of a single pcie per U3 to over come the power loss of the component and stop zombies? Second thought, both A and B combined. Which (A) would probably explain a lot of the reports of the supplied power bricks melting (along with the bricks being cheap). I'm telling you if you use a R1 with crazy guy's custom firmware it's like night/day compared to normal runnning. He added some code that do many things in trying to make a zombie come back. And it appears to be working. I did use 3 on a Windows 8 machine and had to fix zombies a decent amount. So far after custom firmware I have not had to touch them for 2 day's. I will keep testing but I have been blown away by it. |

People in early batches paid a LOT more
It was clear from the start that they would never ROI bitcoin wise. Some had low electricity and had ROI math that looked ok just a long period to make it back. But with new BTC high price it's likely the difficulty is higher then we expected. Now you do stand a lot better chance at ROI if you bought it twords when it sold out. Assuming it ships out on time and no big issues. But it's hard to tell what difficulty does a manufactures likely will try to be pumping out miners as quick as they can. I think difficulty will go higher for a bit. |

Hello,
I'm sorry if this is buried in the 300+ pages of the S7 page, search wasn't very helpful. Trying to power an S7 without having to wire my home with 220. Since the Gekko people are sold out for now, I'm considering using my existing PSU and buying a second one.
I see from Dogie's review that I need 10 PCIE ports. I currently have a CX750M which claims to have 4x ports, but really has 2 ports and 2 splitter cables. So, should I go with something that has 6 ports, like the AX760 or something with 8 ports like the RM1000? How do I know these PSU's actually have the number of ports they claim to have, vs half and splitter cables? Is there just a better single PSU I should just buy for a similar cost?
Thanks!
Mark
I would not use "splitter cables". Chances are unless you bought them on the forum here and know gauge of wire it's to cheap. Also don't cheap out on PSU's it's a investment to keep your miner going. Also it lasts multiple generations of miners. Best thing is to have one with enough PCIe, I would not look into splitters. Instead look at server PSU's and breakout board. Or even antminer PSU if you have a 220/240. |

Yes 20 cent's is to high. You would be better off hosting it somewhere you could get 10 cents pretty easy. Most USB miners cost more then you will make. A lot like me use them for lotto machines And ventilated depends on USB and frequency, some do take a fan if running high freq. Sound is low with them. Sound would be a big issue assuming your in a school one room setting. You could look at S3's for example and underclock. Or bigger and mod it like phil did on S7 -https://bitcointalk.org/index.php?topic=1188217.0 |

I just paid 4.08 BTC [Including shipping] for a Batch 5 about 30 minutes ago. I wanted to wait longer but I couldn't. They showed Batch 5 sold out when I try to buy with BTC price at $440.00. I kept checking back in and finally it said Batch 5 was available again. That's when I was able to purchase at 4.08 BTC [Shipping Included]. Big difference from what I paid for the Batch 1 order. However, I was able to mine 7.5 BTC thus far since October 17th with 9 x S7's.
EDIT: It says Batch 5 is not available again. I may have been fortunate that someone did not pay for their order within the 1 hour time frame.
Yep looks like batch 5 might be out at: Price: 1799 USD ( 3.82 BTC ) Sold Out So that is crazy good price compared to other's. Would not surprise me if they re-open at a higher rate in a day or so. |

Don't listen to anyone, do your own research and decide on your own...
It's different for everyone... yep
Even if you trust someone you should always do your own research. Don't be afraid to ask questions about an investment. Taking time to read may save you from a scam. And everyone is different in how much risk they will take. So find out what yours is, and don't risk more money then your able to lose. |

its high risk if we didn't follow news, market prices and analytics.. in a day on my country, bitcoin rate can fluctuative until 100 USD  What country are you in and what are you talking about? You should have pretty close rate to online, you can use a exchange to get that rate. If you are saying in your country you meet up and get less... you are doing trading wrong. In person should always be more then exchange. If you could explain your statement a little more, I'm not sure I got it 100 percent. |

You could try trading e.g. trading Bitcoins to an altcoin, wait for the price to rise, trade the altcoin back to Bitcoin.
There is also gambling, but of course there is an element of risk.Honestly I think the best way to obtain Bitcoins is just to get a day job and covert some of your fiat to Bitcoin. Much more efficient, and less risky, than trading/gambling. I don't recommend this, but you could also try to scam someone  i like this recommendation except the last one  and for TS, so many thread about how to earn, you should roaming around to gather information then post a new thread. btw this thread became a new source of sharing new idea of other bitcoiners  The first two are not great though. So many coins are pump/dump altcoins are not near as easy to predict. And if you had all holdings in altcoins look at what you would have missed out on BTC value. Gambling is a loss over time. No matter how good you are, over the long term you lose. So you are not investing smart with gambling. Buying is the quickest way to get BTC coins, that is for sure. |

Hello,
I may want to start a little project to make little bitcoin farm, which is hopefully profitable. I want to use usb miners. And what else do I need? Rasperry pi? And how much miners i can use for each raspberry pi?
You need to do some reading. Most mining is done by Asics, which most come with a controller so you plug it in and set it up, and leave it alone. Raspberry PI is a good controller for Avalon 4.1, compacs, lots of usb miners, etc. But you have some research to do as it's a huge range of the different kinds of miners. Just basic check what is your electricity price? And do you have vat/import tax? I am thinking of doing a project with college and they run the miners there 24/7. I read that the prices of electricity in the netherlands is 0.22€ per kWh. Is that cheap or expensive? That electricity price is expensive. You will not have ROI if the difficulty rises 3% every 14 days and pool fee is 2%. Hmm, would I get profit when the btc price keeps rising? Or will the dificulty screw it for me and I shouldn't start a farm? On BTC I judge profit on if I get more BTC then I started with. I do not judge in value of BTC as that would skew the results and possibly show ROI when you lost btc (unless paid in USD). The difficulty could be quite high if it keeps going up. The good news is there is only so many miners they can make, and so many data centers without building more. I don't think anyone can give you a good speculation on what will happen on it. |

hm now price 1BTC=450$ and expect to go more up
where the price of the bitcoin starts to be profitable mining
There is no one point. Mining is so individual we would need to know your information to know if profitable. What is your electricity price? And do you have a vat/income tax? With those we can tell you a general idea, but always ROI math with a mining calculator you trust. A lot are profitable at this point. |

Over 24 hours by a decent amount. 3 U3's all running on 1 R1. It is not having any zombie issues. So far everything the new programming is able to fix. Which truly is awesome.
Thank you for doing the custom firmware! Truly this version is amazing.
That's great! Hopefully I'll have some time to work on compac support this weekend. Looking at 2 day's now. I'm starting to wonder if I will ever need to touch these things again . I would be fine not touching those U3's ever again. It really is making these U3's a lot more reliable. I can leave the house and come back and all are still up... which is very nice. |
