If you are putting the miners in an industrial freezer, and using the freezer to do the cooling, you will need lots of cooling capacity.
It is not the size of the freezer that is important, rather the cooling capacity. Ten S1 or S3 miners will require about 3,600 kW (one ton) of cooling.
It would be of interest to know the cooling capacity of you freezer if you intend using the freezer cooling capacity. For example is it a 3 ton, 10 ton or 30 ton freezer.
Also S1 miners are almost obsolete even if electricity is free. They are only rated at 180/200GHash and each S1 could only expect to return $100 to $200 over its remaining lifetime even with free electricity. You need 20 or so S1s miners to equal the hash rates of one Neptune or SP30 miner. The S1 miners would also draw far more power than the equivalent S3, Neptune or SP30 miners.
As mentioned earlier the S3 is to be preferred - or S1 to S3 upgrade applied.
its a 40 Ton freezer, it was used to store lab results before, its a ''walk in freezer'' with lots of storage, i can go as low as -60• C. i was thinking if getting some Neptune's first but i thought i'd take a look on how the S1 doing before i go for something bigger. If you have access to an industrial freezer and you're going to put miners in there you're doing it all wrong. Rent out the freezer, take the proceeds and buy BTC. You'll end up with more BTC and won't be slaughtering the environment. Putting 4KW of heat inside an enclosed shell is not the best idea - certainly not for energy efficiency. |

BurtW said pretty much everything I wanted to say. Since each Bitcoin transaction follows from another leading back to block generation, any known traceable ID via a vanity address decreases the anonymity of all transactions with that address.
Since payment address for pools are generally not associated with any specific person or entity they remain somewhat anonymous.

It was the eve of my wedding when i got really drunk and poked all over my favorite sofa in the presence my in law.
I hope you mean puked  Back in med school I was driving to a rotation at 5 AM and got clipped in the back by a small pickup - spun around 450 degrees and was perpendicular in the oncoming path of a 18 wheeler doing about 60. It slammed on its brakes and partially jackknifed. It missed hitting the driver door by 1 foot (with no side airbag). Somehow I managed not to soil my pants and was back at work 45 min later. I did code 5 people that day on call and brought 3 back so maybe it was a pay-it-forward loan thing  |

Why didn't Obama negotiate for the release of the journalists when he released FIVE terrorists in exchange for ONE deserter? Five for five would have been a better deal.
I think Obama is sympathetic towards the terrorists. He shares their religion and has seriously stepped back on the war on terror. He has also really not actively engaged the US military with any enemy since he has taken office. For Obama to share a religion wouldn't that mean that he has to look up to somebody/something? I'm pretty sure the narcissist-in-chief thinks he is the highest power onthe face of the Earth. He's not called the messiah for no reason  The admin really dropped the bomb on this one... it will be interesting to see how Hillary spins this to her favor. |

No It's no good at all and I wonder why exchanges accepts all those dump coins, they will never be anything like bitcoin. I'm Ok with Litecoin and Bitcoin but only 2 and not 1000's alts which are just for pumping money from other ..
Exchanges typically have nothing to lose other than database management by hosting all kinds of alt-trash. Since they take a 0.2% cut typically it's free passive money for them as long as the wallet is secure. They can dump the alt-trash coins whenever they want for BTC in their own trading systems. Some exchanges promote every single coin possible, some just stick to the older ones. |

Why and how did you spend 30btc on Minecraft?
I edited my post with the link to the thread. At the time I believe Bitcoins were about a dollar. This guy was selling Alpha accounts, which meant that you wouldn't have to pay again for Minecraft after the beta was over or something. I also bought multiple accounts for friends too. Probably spent around 120 BTC through PM's with this guy, all on Minecraft accounts, haha. Hahaha.. I got your bitcoins sucka...  (That was me...) Seriously though, I think me and Ryland could be considered friends to this day.. and certainly at the time that's what bitcoins were worth. ($1 Each) I'll add to this thread... I sent BFL 186BTC for a 60GH/s Bitcoin miner... got delayed for 13 months and mined 16BTC with it before it became worthless. I think we are answering the question wrong though, because we are answering it as "What is the most amount of bitcoins you spent that you regret today because of how much they are worth now." haha I'll one up you, I spent 209 BTC for my SC Single and it earned 17 BTC back. Recently I bought a laptop at overstock.com with BTC as payment. |

This planes will be guarded and will having hard time getting near on advance countries unless they have good pilot that knows how to evade the radars.
Fly low to get under the radar.. But still possible to see them and report them.. It is so sad, scary and annoying to see rebels take planes like this.. Because you never know if they are going to use them for transport purpases or to ram something like 9/11. No matter what I am sure that they will be shot down if they are found and they come too close to any large pupulated area. depending of the type of planes this may or may not work, but I assume that most of the planes are the average jetliner like Boeing 737 or Airbus 320 and co, I doubt flying it low will work, and I think the best solution is to disguise it as a commercial trip, but again from what I read from the article, the planes has not only to identify to civil aviation but also to military before and when they enter the air space of those countries They can shadow other commercial flights. This needs very professional pilots because they need to came very close to other commercial airplane and also they need to turn off the plane transponder. Making the two planes as one as seen on the radar. That level of flying is beyond what any rebel pilot may be capable of. Getting withing 100 ft of a commercial jet without the wake killing your airstream is hard enough, getting within 5 feet to mask the signature and keeping that formation is something most fighter pilots could not do. Only Hollywood has ideas like that. |

The thermaltake sadly is a piece of crap. Many GPU miners had them actually burn or catch on fire (the 750W model). Coolermaster does have some nice outsourced (since they don't make their own PSUs) higher end PSUs like the 1200, but the GX line is bordering on generic junk. It's possible the S3 is the problem but I would venture that the GX II is the problem. Try using something like a Corsair CX 600/750, a Seasonic or even an Antec single rail Neo Eco 620.

Hello! I have My own power source (solar and wind) should I start mining?
And if so what should my first purchase be?
How much "free" power are you generating? I see that nobody asked you about your power circuit capacity which is strange. Enough to power more then 1000 Antminer S1  Then start building yourself a room where you can have some kind of wind tunnel to evacuate the air as fast as possible with some big ass vents and start mining! Do you have any suggestions on how to build a wind tunnel? Really? Big industrial fans blowing cool air from outside into the room and big industrial fans exhausting hot air from inside the room to the outside. If you actually have the excess power that you say you do, then getting rid of the heat build-up is going to be your biggest challenge. Is there a problem when more air is blowing out of the building than into the building? There's no reason to reinvent the wheel. We have pretty much every possible iteration of mining setup represented here: https://bitcointalk.org/index.php?topic=7216.0Yes it's a lot of reading and pics - but if you can't devote 2-3 hours to planning you should be allowed anywhere near 1000 S1s. |

If I were you I would offer to host a couple of miners for somebody else and charge them a fee for the electricity. Win for them, win for you. By getting a miner you stand to lose money currently.
Your small amount of electricity may be free, but you do not have free space, free cooling, free time (to babysit the miners - well maybe you do as a college student) nor free capitol to buy many miners.

If you can sell a $100 miner to the public for $500 why not? Then you can take the $500 in revenue and buy 5 of your own in-house miners and the net result would be 6 units added to the network at the cost of 1 to the miner company. The miner company would get 500% the hash/$ as you do and have minimal downside with increasing difficulty. If they didn't have plans to do so now they do |

I got a call from cointerra today basically because I was one of the suckers that preordered from them last year. He first asked me how my miners were running and I told him I had to sell them all 5 of them three months ago because they were a huge POS. They consumed 50% more power and ran 50% slower than promised. They were very unreliable and super noisy.
So he went on to try to sell 5 more of them for ~$3700 per unit. They said they run at 2TH now and consume 2600watts...I said 2600 watts!?!?!? are you kidding me? I told him no way and check out the bitmaintech antminers. much better deal.
You can buy 6TH worth of antminers for the price of one Cointerra 2TH ($3700 plus shipping =~$4000) and it will use less power/per gh and run cooler and more reliable and quieter. Basically 3x the hashpower for the same price.
They must be taking a page from BFL playbook. Several of us previous BFL customers got calls from a call center letting us know about about a 20% discount when they had finished their 65nm backlog. I told the rep about how horrible the entire ordeal was - he asked if I would be interested in placing an order.... then silence for 30 seconds  |

Remember the good ol' days when we could mine at least 100BTC with only a CPU ? In a few years people will also tell on forums : " remember when we could simply mine with Asics ?" Evolution dosn't care of nostalgia  I'm pretty sure ASICs are the end of the evolution since their very name means that it is a circuit made for hashing. The only next possible evolution would be something that isn't a circuit... a hashing lifeform like a SHA-256 bacteria |

I have been a EBay seller since 1997 and this has always been a problem but has gotten worst as more people find out how to play the system. I sold a lot of USB miners and then my BFL singles. Always holding my breath but I did put on my auction that buyers needed to have at least 10 positive feedback and canceled a couple winner bids because buyers did not have it. But anymore since a seller can not leave negative feedback to a buyer the whole feedback system sucks. There are ways to protect yourself as a seller and one way is never have your bank account linked to PayPal or EBay. Get a very low credit limit Credit Card or I use my Discover Card and have had Discover stop unwarranted charges. So I pull my money from PayPal as fast as I can and leave no money in the account. The only way they can force my refund is thru my Discover and you can stop a charge back. I used the no refund on the auction and this was always going to be my way out with Discover and they will fight PayPal for you.
Edit: also always ship USPS that way the buyer has committed mail fraud and if you really get pissed you can file a complaint with the postal inspector , just file using the buyer and EBay. That is what needs to happen to put a stop to this!
I did that same as you but eBay will actually send you to collections very quickly if they can't collect from your credit card. I filed a complaint with CA State AG and hired a lawyer to sue them for dereliction of duty. I ended up getting the collection removed and it cost me about 80 hours of time, but I probably cost eBay/Paypal well over $30K in legal fees. I haven't sold anything on eBay in ages. If I ever come to the point where I think I want to sell somethingon eBay I just donate it to a charity  |

For what it's worth, BFL claims that they will ship some Monarchs this week. How many, and to whom, has not been disclosed. I think these are supposed to be operating at 600-700 GH/s.
Not a BFL supporter, just reporting current info from their website.
Yes - I too have heard rumors that they might be shipping soon. Well the rumors are over now, it's confirmed! On April 2nd 2014 they announced that they anticipate to be shipping SOON! None other than the venerable shipping master BFL_Jody herself!  |

Miners spent the entire last 1/2 of 2013 and first 1/2 of 2014 throwing money at ASIC vendors. Those vendors are now putting up their own farms with those resources. Not just Bitmain. Not just KNC. Not just Cointerra. The whole lot of them (sans maybe the black sheep BFL).

Buy Antminer S3 or buy Ghs in PbMining?
see my thread here: https://bitcointalk.org/index.php?topic=739510.0Then ask yourself if I sent $2000 to PBMining and they disappear after 2 weeks like lunamine did, what are my options. If you're willing to risk your money after reading that then a lot of other miners have bridges to sell you. If you buy an S3 now you will not get it for over 1 month. I suggest waiting for new hardware to come out if you feel inclined to mine. |

Do you think that if i do buy some miners, let's say 1-2 TH/s t start off with, will i be able to pay them off with mining ?
No. Did you notice that difficulty jumped 20% today? That's 20% less earnings for the rest of the miners life since difficulty is probably not going down until 2016 when the 1/2ing occurs. In 12 days there will be another increase. If you like mining and are willing to lose money to do so then feel free to do it. Unless you have free power it's not currently viable to make an ROI. i have free power, that's why i'm asking if i should mine and if i would earn on it. Free power - check. Free space - unknown Free cooling - only if you have fans, AC and venting ready Free peripherals to support mining - ethernet cables, switches, router Free miner - to be determined If you're going to use 1 or 2 devices then you don't need to worry about infrastructure. If you're going to have a mini farm then you need to spend money on the above unless you already have those items. Please look at the ahrdware forum and the pics of my mining rigs thread to get ideas on what you need and how to do a setup. If after than you're interested then go for the lowest priced miner/GH. |
