you need to go big with this type of thing otherwise you will only earn few pounds like he said in the video
but at leats it remain profitable, maybe because he sold old miners to have the new equipments
It is a neat idea. But going big with this is just not best way as far as profit. Look at all that equipment for 1 S3. I consider solar and bitcoin mining two different investments.You will make ROI much quicker from finding cheap regular electricity. Then there is no additional equipment cost for something such as solar. I wish solar or wind made sense but just does not large scale compared to moving to the cheap electricity. This is it exactly. Its 2 separate investments that produce their own income, 1. You can sell mined bitcoins 2. You can sell solar electricity so why not keep them separate from the beginning? Also, most of the time you get a fixed price for feeding-in solar generated electricity. This could be e.g. 15 ct/kWh. Now, if you mine less than 15ct worth of Bitcoins with 1 kWh (aka a 1000 watt miner running for 1 hour) then it is not worth it any more to mine coins, but you would be better off selling your electricity. The other thing is if you already want to invest in solar power at the same time, I am not getting why it has to be directly connected to the miner if you live in a residential house. Just attach solar power to your home network feed back and forth in the grid depending when you use more or less than you generate and simply plug your miner in the sockets. Using the national grid as a battery is the cheapest and most reliable option. Nevertheless, it looks like a nice project and must have been a worthwhile learning exercise. If one has a few panels lying around, why not make them pay back for themselves. You say it very well. I want to add I don't hate the idea. I really like the idea of "eco" miners, but I like my ROI much better. I live in decent priced electricity so as far as me investing it is hard to justify solar/wind. If you live in a very high priced electricity (or place with lots of incentives) solar could be a good investment. But it is a different investment then BTC. |

Very interesting on some of the information. So does the official exchange not really mean anything? I find this "black market" interesting on currency just never dealt with anything like it. Who do you go to to exchange cash? Would a foreign investor be paying the official exchange rate?
There are at least 4 "official" exchanges here: Wow thank you for putting such a great response together. It's honestly better anwser then any of the stuff I was finding on google. Mining does sound very interesting there. |

yes it's a dragon miner 1 TH from LKETC , i still got one of these to sell  They really were great machines. PSU's were a little cheap. But I'm looking foward to LKETC's future products of next gen. |

Enquired about S5 boards and controller. About $500 to get part's but no warranty if put in C1 case.
However...
This is what they said at the bottom of the email;
"if you are in no rush we have some nice things prepared for near future so stay tuned."
So I am guessing I am going to get rid of my hash baords but keep the c1 case and do a watercooled single s5
I don't see them doing water cooled again. I could be wrong on that. But I'm thinking air cooled in future. But you are right the parts could be used to make S5 boards water cooled, I know I have seen it on forum before. |

BTC-e is huge exchange, but it could be dangerous since the owner is anonymous & their customer support isn't too good You better use BitStamp or BitFinex. BUt, you also can use Coinbase or Circle since the process is easier Yes, it could be dangerous since owner is anonymous but not dangerous as "owner-known" exchanges like Coinbase, Bitstamp, Bitfinex and Circle. BTC-E is one of the oldest bitcoin exchanger. I've use it more than 2 years. I've traded more than 100 btc in btc-e with no problem. Having known the owner doen't make it secure. Look at the big sh!t mtgox that was owned by karpales and many other exchanger and bitcoins sites that has known owner. It is a very popular exchange. It just is not known for the most timely support. If in US the above exchanges might be better for user if there is a issue. |

Hi Guys
Thanks for the inputs. I spend a lot of time playing with electronics so in many respects this is just an interesting learning experience for me. Just buying Hash & Trading is not what I am after, I still remember loosing a lot of money when the Tech bubble burst...
So if you need Electric at 5 Pence (8 Cents) / KW then that means anyone mining in the UK is loosing money and I guess those in the US not making much?
This was my simple rounded / approximate maths based on my very limited experience mining with the S1 on PPS sites like F2Pool, NiceHash & BTCChina all of which gave similar results.
S1 running at 180GH/S consumes 340W @ the wall, ( 2J/GH) 24Hrs running yielded .002 BTC = approx 60 Cents
So cost @ 15 Cents / KWH is approx 8 * 15 Cents = $1.20
So a loss of 60 Cents every 24 Hours, not good but the washing is dry.
So now looking at a miner running @ .5 J/GH so 4 x the efficiency of the S1
So if the miner was running at 800GH/S this would yield approx $2.40 in 24 Hours
Electric cost should be the same @ $1.20 in 24 Hours, so a profit of $1.20 on current difficulty.
I will do the undervolting / underclocking on my S3 and see what "real World" results I achieve and take things from there.
Will read the thread & keep an eye out for the Sfards chips.
Rich
S3 is good for those with cheap eletricity. On SFards I would not count on them to soon. They have been very quiet. LKETC is also one to watch. After they get their next gen we know they have been very successful in past at mass production. |

I recommend you keep most coins in cold storage and do not rely on an exchange to hold your coins long term
This is very good idea. Either USB drives with it or paper wallets. If done properly do wonders. It means YOU keep control of your BTC no matter what. This is huge not to mention if done right it is much safer. or a hardware wallet https://bitcointalk.org/index.php?topic=899253.0only if it'is really cheap like beatbox or hw1, i'm against suggesting new comers to spend 100 for something that is even difficult to understand for them My hate with hardware wallets is when someone new buy's a used one. Always buy a new hardware wallet from a authorized source. If you buy used sure chances are it's ok. But you never really know for sure and it could have been tampered with. |

Why don't we just SPAM them, with the question; IF and WHEN they this S2 Upgrade comes?
How many people are following this Topic? 100, 200 or more...
What if we start emailing Bitmain every day -twice- with lets say 100+ people?
If the arrogance of Bitmain is this high, they need a good lesson!
Believe me, after a while they will answer!
ps. soon LKETC.com is offering 5TH \ 1000watt (maybe it's time to walk away from Bitmain...)
omg....you are right http://lketc.com/enindex.aspxDoes anyone know the price yet ? The price and release dates are not known I do not believe. I'm guessing they are still working on this chips myself. |

So is there a list of the States that oppose bitcoin or have even run people into trouble and vice versa,those that are ok with it?
Also has anyone run into trouble with border security over bitcoin?
Thanks
In my country, using bitcoin is not legal, but not ilegal. You can use bitcoin but the gov never suggest this and don't have responsibility with it. I don't have any trouble, yet. Like @notlist3d said, the exchanger is the one of trouble too. Same like in my country. And I don't need to deal with it. But there is one problem with taxation from selling bitcoins, when I send it to "regular" account with "regular" currency, becouse bitcoin has not prize for the goverment. So there are few ways how I can tax it, but maybe not every is the right for the goverment. Well, until now i don't need to pay a tax when i used bitcoin, i just need to pay fees with my local currency on my local bitcoin exchanger, maybe it could be my tax and fees for the exchanger at once IMHO. I think in future when we have more acceptance taxes will come in many places. Right now it's exchanges making sure they are legal is where most countries/states have started. Taxes are not necessary bad it means we reach a point where BTC is well known. And hopefully BTC will grow in value. |

Why is that a problem? This seems to be the way most miners choose a pool - they go with the biggest one. This is the reason Deepbit became too large, then BTC Guild, and later GHash. Right now Chinese pools have over 50% of the hashpower. This means that just like the US government controls Visa and Mastercard, the Chinese government now controls bitcoin. This is a very bad thing for bitcoin. You may also want to consider that there is a warning at bitcoin.org to not use the pool you suggested because they are mining blindly: https://bitcoin.org/en/alert/2015-07-04-spv-miningIf you care about what happens to bitcoin, then think about how you use your hashpower and how it affects bitcoin. The future of bitcoin is probably more important to you than it is important to be doing the same thing as everyone else (why is that even important). Also it is PPLNS at 1 percent. You can find a good amount of PPLNS that are no fee.
Do you care about the fee or the final payouts? 1% is not much and there are many other factors involved. Some pools don't pay out income from transaction fees, have a high orphan rate, pay for stale work (using your mining income to subsidize miners with bad internet connection), or don't have merged mining. I had a large miner (at the time) who was very happy with the customer service and other things at my pool but he felt it was unfair that my pool had profits, so he left for Ghash. Then Ghash scammed a casino (they say the employee who did it no longer works there). And their payouts were about 10% below average, probably because they had a vulnerability that some miners used to get their work counted multiple times. 10% is a lot more than 1%. I understand that miners will not take all these complicated factors into account though. I guess the fee has become like the pixel count of cameras, it's a product reduced to a single number to make it easier for you to choose. Maybe it would look better if transaction fee income and namecoins were kept by the pool, but the fee was reduced to 0% ? I am in no way saying they are horrible. There is just better out there. When I have a offer of a big pool at PPLNS at 0 percent, or a small pool at 1 percent for same PPLNS. I will go or the 0 percent. Again personal preference. It's not a horrible pool.... just obviously not popular pool. |

If they already sold out the 1st batch, what's the urgency for them to try and sell here? Maybe when they can't sell whatever they make at $1200+ per unit. I still there there's a $999 Christmas special (almost 30% off), in the future..... How do you even order from them though? I still have yet to figure that. Is it just via email? If so what email? |

I have had a few people interested thinking I am trashing it. This miner and cooling gear I spent a small fortune on. I'm not looking to trash it.
I have another one I can keep it for parts. If a good offer came yes I would sell, but again not looking for parts price and splitting up.

Ck or Dogie or anyone, Can someone explain how to use the Sept 26th Firmware with Cgminer 4.9 with extra nonce?
Installing thru ssh to make sure it stays put thru a reboot???
I wanna be able to use the first firmware with the latest miner so i can use voltage control to downclock my miner.
I don't believe Bitmain has made a firmware that supports extra nonce. It is something very few use. Chances are your looking for nicehash and the firmware they custom made to support it. I don't know of an official one with it from Bitmain. |

Guys and gals, Gridseed priced their miners to NEVER ROI! Only those looking to mine at any cost will buy at first, eventually they will drop prices fast enough to keep up with actual profitability but nowhere near when they finally start shipping. There are plenty of people willing to overpay so they don't care about losing customers. The G-blade was $3k when they released it, within weeks it was less than half that. They are not going to sell us gear for reasonable prices when there are those out there willing to pay unreasonable prices just as they did with the gridseed miners. Resellers will be their customers, and they will have buyers willing to overpay. That was how GAW became a "company" so they will repeat the same profitable process for these miners.
However I have little faith in LTC, price or purpose, after halving and no interest from bulls speculating, the price will drop and this being the most profitable miner will be one of the few left to mine LTC profitably which will lower the difficulty. Nobody else is working on scrypt miners, so you may have an opportunity to mine a shitcoin at lower operating costs than anyone else for a long period of time, which will allow you to recoup some/most of your investment. Not a reason to pay more than the miner is worth, but a possible added value to the miner that MIGHT justify paying a premium for the miner.
I wish I could tell you fuck off you are just a troll. Fact is I pretty much completely agree with you post. Sfards never really did much to prove your idea wrong so far. Trolling has been getting bad lately in certain threads. SFards really needs communication. I'm surprised they are not on here trying to sell. Even if next batch is a over a month away... if it was me I would be trying to sell that batch before the day comes. Just the discreetness is odd. I hope they come out selling and sell for cheaper then reported. But guess we will see. |

The actual connectors (per MOLEX datasheets) commonly used on PCi-E power connections are specified for 8 amps per contact (the contacts themselve are seperately rated for 11 amps but that is an OPEN AIR rating, you have to derate for using them in a multi-contact connector due to heat retention). This works out to the +12 connectors on either a 6-pin OR an 8-pin PCi-E connector maxxing out at 288 watts (which is where that maximum "Max PSU Power Unit" figure per connector/loop on the SP20 comes FROM).
You're have to be overclocking a S5 to exceed that rating on one connector - but it's STILL a bad idea, as the boards aren't designed to be run from a single connector and you're likely to be overstressing some of the +12V traces ON the boards a lot by misconnecting the power leads.
This is the reason Titans have so MANY power connector issues - they DID exceed the rating of the connector even at their STOCK clock, pulling over 300 watts per connector (the extra 2 pins on a PCi-E 8-pin connector are both GROUND leads, IMO a rather dumb thing for the PCi-E spec to have done - sure, the ground leads run cooler, but that doesn't appreciably help the +12 leads).
Keeping the bottom of an S5 on a flat surface helps cooling overall a LOT - raising it up lets a LOT of the airflow escape without cooling anything. It's even a good idea to try to close off the open parts of the top to help cooling some, but that's less importans as the controller board blocks quite a bit of the top airflow excape route.
its not the pci-e connector you should worry about.. i would NEVER run a miner with only 1 pci-e on each side... even tho its "in spec" this will probably happen.  That's why it requires 4 connectors. Sadly people try to be cheap and try 2. Two will work on a S3 it simply does not use as much electricity. With the S5 you have to have 4 lines of power. Not 4 connectors, but 4 lines coming from psu. PCIe was not meant to run sub 600 watts on two wires, so it needs 4. |

to get 0.3BTC a month you would roughly need 1000GH/s at current difficulty
that being said and efficiency not being a factor your quest to find miners for $200:
6 antminer S1 = 1080GH/s ~ 0.319BTC/month you would have to find them for ~$34/each
3 antminer S3 = 1323GH/s ~ 0.390BTC/month you would have to find them for ~$67/each
1 antminer S2 = 1000GH/s ~ 0.295BTC/month you would have to find it for $200
Now that is without psu's
as far as noise the S3 is the quietest of the 3 and produces the least amount of heat but finding them for that price will be hard to do
I searched the price of these miner, its too large. S1 miner for 150$ app S3 miner is for 800$ S5 for 13 btc Do you have @cheapest price that you posted? They are all way to high I have no idea where you found those prices. Look on ebay. S1 honestly is just to old. Look at S3 as far as price, but consider your electricity price. S5 buy direct from bitmain for much cheaper then 13 btc. |
