By your standard (less than 8c/KWH) my electric is cheap - yet I've NEVER had any of the calculations I've done show that the S7 will ever pay off. Usually not even all that close to doing so.
VERY VERY cheap (3c or under) maybe, though right now even at the way-too-late drop in S7 pricing it's still looking VERY iffy.
NOT 7.5c
I would agree on cheap being closer to 3C or so. The big guys can chase this electricity price and build where ever they find it. This is why they have a huge advantage. Some gear even at halving at 3C chances are they still can run. Us more "regular" user's would be 8-10 cents or so I think. And above 10 get's tough unless your one of those who say's they use it for heat in winter... then it get's a little more complex. |

@OP,
Why don't you go for a single s7 which gives you higher TH/s with greater efficiency and lesser consumption???
The math you are showing is based on older machines which means that there is no guarantee that you can profit with the amount of miners you are going to use, as the electricity is higher at your place, and most importantly, it is associated with your ROI period...
It is hobby mining for him. He can only afford S5. S7 costs more than $1000, that is too expensive. As I mentioned OP appears to be gone I think we can let this thread die. But you must have missed his top electricity at "$0.32/kWh" which is very very high. Were talking so high it makes it hard to mine at all. If he runs anything he will want most current he can get. Do the math on S5 running at that electricity you will see it is not good at all. |

Well the Hash rate is still well down, unless someone powers up some Miners soon we are on a negative day.  I think we could see as few as 130 Blocks. Rich Edit I may have scuppered things, blocks have just started piling in...... F2Pool is on fire, 6 Blocks in 15 Minutes... I think we will end up with a high change compared to our lucky months again. My hope is it is smaller then last. If we get smaller each difficulty period on change... that is a little win. Bitwisdom still has us kind high: Bitcoin Difficulty: 103,880,340,815 Estimated Next Difficulty: 111,923,700,649 (+7.74%) Adjust time: After 1065 Blocks, About 7.2 days Hashrate(?): 809,776,347 GH/s |

Hi, Have been browsing the forums and learnt alot about bitcoins here. So, firstly, I would like to thank everyone who shares their experiences in this forum, and also you, who is reading this Second, I am thinking of purchasing some miners, Avalon A6 or antminer S7. Wondering if it would be better to purchasing new ones, or would it be better off purchasing used ones? Also, where should i go searching for used miners? I have recently read about BitFury's new chips, and some speculated that it would reach end users by Q2 2016. Should i be waiting, or should i purchase some miners right now? Thirdly, I visited a mining farm of my friend's. I was thinking of installing air conditioning in my farm but he shared with me that he used to do that. but now, he simply suck out the hot air using exhaust fan. Can i ask for some opinions on cooling? Thanks for all the help! PS: I'm running on very cheap electricity, almost negligible to our costs. Right now I would wait for the next generation of miners. The difficullty will make the current one go useless (in terms of getting ROI) within months. But buying 1 or 2 used miners would be a good idea so you can learn about it. He said very cheap electricity we really need that defined by a amount before we can give good advice. We also don't know when next gen miners will be out for general public. A lot say "I'm waiting on next gen" and never pull the trigger as there is always going to be a next gen. But OP what is you price of "cheap electricity, almost negligible to our costs". If we know that we can help much more without that it's kinda hard to help. |

With a 1000 bucks i would go for either some second hands 3x S5 with PSU
Or get a SP Jackson with PSU.
However don't forget to calculate your earnings.
Either a couple of antminer S3's or antminer s5's. I know spondoolies tech made good hardrware but I am with bitmain since day 1 and I know their hardware is one of the best, maybe even the best. I would not recommend to buy a S3 at. The S3 is what a S1 was 1 year ago. Ofcourse the price is cheap (80/90 dollar), but with this difficuly you will not get your investment back. It's just the nature of mining gear goes down in price the longer you have it. S3 you need really cheap electricity or free electricity at this point. For those lucky ones with free electricity they can get it and still profit. S3's are tanks and will be around for quite a while. Just are going to shift to lower electricity areas. Nah if you buy an Antminer S3 for around 80/90 dollar you won't get your money back. First of all you need to buy a PSU which cost money. Then check your daily earnings. With that in mind, the miner will need 1 year to even get ROI, by that time I doubt if all of them are still working... A lot of miners have PSU's from miners that already ROI'ed. I don't sell PSU's so I don't always have to buy one, only if I don't have a sutable one do I buy PSU. And you cannot say they wont. There is some who are lucky with free electricity, it might not be a quick roi but eventually they should. And it's those free and super cheap electricity is where S3's are going now. |

I have already applied and send pm but still not reply any way round ..can you please tell me if we can do it or not
That would be a no then. You have to get Marco to say yes before doing all the other things. With it being closed if you do all the other thing's your just wasting your time. If you have something special send Marco a PM. But as far as for most it is closed. It is kinda confusing with so many trying to join each page, but it is closed overall. |

Is the harddrive still bootable?
If so and you were using cgminer with the old-school command line, all your commands could be stored in the OS. I can see all my recent commands with the up/down arrows.
Edit: Just tried it... had success with linux, but not with MS.
If not booting I would try to put it in another computer sometimes you can still see the drive and it is something with boot. But OP really needs to know if it was on hard drive or if it was online wallet. Right now there are a TON of possibilities. Cant really help till he tells us more. |

Ive ordered some antminer s7s and got the recommended power supplies but they are rated for higher voltage (from china) than standard usa outlets. What should I do? thanks
So you have the antminer psu's coming in? basically you need to hire an electrician to put in a 240 volt 30 amp line. Is this feasible? Yes, antminer's psu's are coming. I would do the wiring myself but is that the only option? What about a transformer? Anyways, I'm mainly looking for a 110 PSU, such as a high end desktop PSU? (I would just sell antminer's psu's) How many miners did you buy? This gives us a good idea of amount of watt's. The bitmain server PSU will not run on 110. Who are you expecting to sell to on it? But transformer ... no most likely it is breaker box and you would need to know how many amps you have, if you have enough extra for it. With you mentioning transformer I might suggest calling a electrician. |

Free electricity. Antminer S7 running 24/7
I guess what I'm asking is how profitable a 1T is with free power.
Depends on price you pay for the 1T as far as profit. If your just wanting to see what it currently mines I like: https://bitcoinwisdom.com/bitcoin/calculatorWith it you can do difficulty the ones like coinwars and such that dont have difficulty so they are really far off. And we cannot guarantee future difficulty makes it speculation, but still hard to tell exact in a month or even month's. |

If you can afford the sync time and the bandwidth and the disk space, go for the core, the less error prone wallet around
If you have a paper wallet you could use it with most wallet's. That is the beauty of paper wallet's. As long as you don't spend them do it right you are secure and can use many different wallets. If you need use I really have switched more to hardware. Depending on your holdings I really suggest people looking at them. |

I understand nothing about this cloudmining since all my earning is 'unvisible" a,d my GH/s "inactice" and you ? do you understand? I think that is saying all old investors are done... now they want to offer one they say is higher performance. What is old hardware you were using? Also what will be the new "high performance miners were ready". With being ready seems you could say what miner your using. |

I personally started few days ago and i bought about 1.5 Btc. Im looking to buy more and more.
Thats nice ,but i`m more curious about people who earn BTC in this survey. Buying BTC doesnt give any useful information for this research, i`m curious how much can newbies earn. Was reading through thread a little more since last time I did. I could not find it when will you release results? Also what are you plan to do with your findings at this point, I was curious what your plan is? |

Hopefully you find one. There was only a couple of options to me as I a a newbie
Did anyone check his post history: https://bitcointalk.org/index.php?action=profile;u=693213;sa=showPostsIt's a LOT of few words posts. Not on Chinese but it's short to. If he adds a sig with current post types he will be banned for insubstantial posting. I highly suggest wait till a few month's and learn more about the board and bitcoin. You really don't get a good pay till full member. |

i have done all process but the bot don't show my account si not active ..can you tell me why ??
Joining is closed right now. If you talk to Marco in PM and he approves you then you can join. Did you just follow directions below it saying it was closed and not talk to Marco first? |

Thats what I'm trying to find at the moment but cant seem to find which file it was in.
Was hoping someone here might know
Do you have bitcoin core as asked above? If not do you have a wallet on your computer? If it was online... depends on where you stored it but if it was in 2011... it's hard to say if site is still there. You would need to know site. |

Looking good jstefanop  Any idea on final cost per unit? Final cost is $32 plus shipping. Do you know when it will come time to pay for the rest we owe and shipping? Just curious on time frame. |

only worth it with free electricity i guess, because even at 0.05 the profit isn't that great(actually there is loss with the next diff increase), probably on par with some gpu mining on some random altcoin
Worth it if you aren't just in it for profit. For some this is a hobby. But for the OP who mentions ROI definitely not worth it. For the price these are pretty nice hobby machines though. I run a decent amount in my hobby mining. I see hobby mining as bigger then home miner but less then a commercial setup. I think this area will grow as it's much nicer to have a mining area then running in separate room's trying not to trip breakers. But that is another story. You have to be in it for a profit at some point. I cant lose the amount I am currently paying on electricity, or I could it jut would be dumb. If it got where I could not do it profitable I might run 1 for fun. If a miner no longer make me money I sell it to someone with cheap or free electricity. I think you underestimate the cost of running a modern miner over time especially. |

+8.2% = tennozer
I won't do mining again, difficulty increase is hurting home-miners very bad.
I dont know about that. The BTC price also doubled, so about the same income as i had few months ago. All in all, not bad. S1's are still profitable + i need the heat anyways. For most S1's are not profitable you are really lucky for your free electricity. I would spend more on usage then it would make sadly. But that is great for you. We had a long time of low difficulty we might have even got spoiled with it. Now were seeing difficulty changes. Either price goes up... or some last gen gear will be sold most likely after winter. I foresee a lot of S5, SP20, Avalon 4.1, etc being sold either a little before summer or right into summer. But that is a lot of time... if price goes up it might remain profitable for longer. Just hard to speculate it. |

With free power, what would be the ROI on a 1TH/s miner? Thinking of an S7 for a pool.
It's not one size fit's all on mining. So many different things that effect this. What machine are you looking at? (There are a ton of 1T's). What price did you get it at? What is your electricity? Etc. So you need to tell a lot more info for us to be able to help. |
