Let's say that I did purchase one, however. At the current network difficulty and BTC exchange rate, that S5 would expect to make ~$3.25 a day before power costs. ROI would be ~123 days. Using a very conservative network difficulty adjustment value of 2%, we're up to ~136 days. That right there should have convinced me not to purchase one in the first place... and I assumed free power in my numbers.
That's lack of enterpreneurism... Common business reaches ROI 2-3 years after initial investment. We were (are?) seeing month-scale ROIs because of the highly speculative price of bitcoin. If (when) bitcoin becomes more mainstream, expect ROI in a year or two... not less Disagree, but only by time frame ROI will be 8 months not 12 to 24 for 8 cent power. 60, 90, 120 days for ROI is pretty much over. I have higher power cost then many So ROI will be a year for me. When I buy I time for my winter power price which is 10 cents net. I Like to mine from October 1 to March 31 then sell off the gear. Aside for above. Bitmaintech has not been the supervillian people make them out to be I know many people hate on them. In fact I have decided to hold off on my s-5 is it working or dead thread. I did one for the sp20 and that gear looks to be over 92% alive according to info on more then 300 pieces of gear. I read this thread and I see a lot of angry people. I do not want to open a thread on it works or it is dead and have to edit hundreds of complaints due to the hate against them. I would like to do it with the s-5 maybe I will start it this week. |

Hopefully MrTeal and at least one other can post some news of the sticks. Last I heard from vs3, he was having software trouble I think and hadn't gotten any sticks to light up yet. Once we have at least six favorable reviews, if no serious issues have been found that need to be addressed with a redesign and retest, I'll give a three-day warning on opening sales.
I think what I'll do is limit to 10 sticks per person, except for people who have already gotten ahold of me about bulk purchases. If you haven't done so by the time sales open, you missed your shot because I posted last week that folks wanting more than a few needed to get ahold of me directly.
Sounds good I am looking forward to my batch. |

I use the 5 btc to rent 500th from west-nice has and point it at solo.ckpool.org
As long as I pay .0094 per th for this diff adjusment it is an investment not gambling.
Granted is is a high risk investment you chance of winning 1 or more blocks is about 20% but you are getting about 25 btc back for the 5btc.
If you pay more then .0094 per th you are gambling

Ouch price is now taking a dive currently at - 284.75 This is a drop of over 8 percent or 25 dollars. Price is still not horrible as long as it does not plummet more. But would be nice to get over 300 mark again. http://www.coindesk.com/price/dropped a bit more.. Well this is why waiting to block 300 to pick helps a bit. If everyone picked yesterday when coins were 310 picks would be as high as 5% and 6% based on this site which is more of a real time number we are negative we are 208 blocks in so figure 14 to 16 hours time and we will open for picking. http://www.bitcoincharts.com/ (-0.036%)Blocks 365104 Total BTC 14.378M Difficulty 51076366303 Estimated 51057804323 in 1808 blks Network total 327993.542 Thash/s Blocks/hour 5.38 / 669 s So over night a big drop. Oh coinbase needed to shut down must likely panicked sellers caused that. Look for them to open later today. Feel sorry if you ordered an s-5 at the new higher price of 439 plus shipping. Good luck with that. |

I'm in notlist3d's camp. Interested, but it has to make sense from an ROI perspective.
Right now there just isn't enough info. But once the price and and other details are clear, hopefully it will make sense, because they look like fun.
Fun helps. Quiet will help. It could be an office miner. And no will notice it as it will be quiet small and draw under 35 watts. |

I'm worried because every time in the last year and a half that I've brought in a large amount of BTC from sales or hosting invoices, the price suddenly dropped before I could cash out. And within the next week I'll be listing for sale something like 50BTC worth of stuff, so really I expect the price to drop at least 10% about Thursday (assuming I sell on Wednesday).
HAHA! Yes, I am thinking of getting some more btc, and if I do then the bull run will die and it will drop back down to 250$, because that is always what happens! But yes, I think that there may be an increase in mining equipment costs. I noticed that on hashnest the price of hash has a strong inverse correlation to btc price, but with this last week run the price of hash has been pretty solid and does not show the usual inverse relationship as strong as it usually does. To me this shows that people are willing to pay more for hash/mining equipment as price rises. And honestly, when I bought in to the hash it was .3% a DAY, which doesn't sound like a lot but geeze there should not be any investment that pays so much, because usually investors will bid this up until the return is lower. As the market cap increases, and you see more traditional investors get in to the game, expect these strange market inefficiencies to minimize over time. Sooner or later hashnsest should have a 10% yearly return, not monthly! But I think this will also be the case with equipments, up to a point. Damn you killed the run by just talking about making a coin purchase. We dropped to 275! |

I think the 4-chip pod is a more logical target. It should be possible to make a single board which fits both the Gridseed and U3 heatsinks; I'll have to get ahold of an RBox pod to see what it'd require but I know I can hit the other two for sure.
I have to applaud your designs. If you could make one to fit in greedseed and U3 heatsinks that would be a very very nice product. The good thing is there are A LOT more gridseed pods then new rboxs. So much this cheaper price for equipment to put it in. Although I do see why some want R-box it has merit as the amount of chips. I personally would enjoy playing with a 4 chip modded gridseed pod. If you go though with this design I think it's a great idea. Either way you choose though best of luck. I have been playing with the 1 chip usb model still and has been fun, and still working good. like you I am still working with the 1 chip sticks they are very nice gear. I get the felling they will run very well for a long time. |

I have exchanged some emails with them about a review model of the new mini and a group buy of it . Review model = late July group buy = Mid- August But time will tell if they can meet the times above. They did get me a model of the 4.1 for review very quickly. So I hope they can come through with the mini on time. |

well if your room temperature is fine, and your miner are working cool enough, you should be doing good already
you should aim at around 60° max, at least this with the antminer s5
There would be intake fans pulling in fresh air from outside, so that would be the room temp before going through the miners. I'm just in the hypothetical/planning phase to see if it would make sense with a bunch of miners in a warehouse and what it would take from an exhaust standpoint. room size helps to know it, but a 3000 cfm fan changes the air every 2 minutes in a 20 by 30 by 10 ft room (Under perfect conditions) So look at 3000 cfm as the exit fan and 2000 cfm as the fresh air fans as a minimum if the room is 20 by 30 by 10. Many do this: ^^^^^^^^^ hot air leaves the building window window ^^ ^^^^^^^^^^^^^^ fan fan fan fan fanminers miners miners^^^^^^^^^^ fan fan fan fan window window window cold air outside the building |

in other hand...you are still considering Bitcoin Core as Desktop application? Maybe something changed recently, but I still remember, that after each reboot was my 4 years old laptop ~30 minutes almost unusable, because core start syncing blocks from previous day and I didn't have SSD back in the time:)
Well you called out the reason there-- not having an SSD. I run bitcoin core on a battery life optimized ultra light laptop and never notice it running. That its a fine desktop application doesn't mean that it's super awesome on a 4 year old non-ssd enabled laptop. The much larger blocks these days do require more work to catch up on, but the software is also quite a bit faster. Do you need to have an SSD that can store the entire blockchain to benefit, or you can have the software in SSD and the blockchain in a HDD and benefit? I say this because SSD is way too expensive, and the blockchain is too big, in no time it will be way too big to store the entire blockchain in regular HDD; let alone the expensive SSDs.. well lets see op have 120 btc which = 120 x 300 = 36,000 when he posted it was 120 x 250 = 30,000 a 250 gb ssd = 90 usd a second 250 gb ssd = 90 usd a 1tb hdd = 50 usd and a hdd/ssd cloner = 40 ssd grand total = 270 usd 270 usd or 30,000-- 36,000 usd. link for the ssd: http://www.amazon.com/Crucial-BX100-250GB-Internal-Solid/dp/B00RQA6TEI/ref=sr_1_2?link for the hdd oh 58 usd not 50 http://www.amazon.com/Toshiba-5400RPM-SATA3-Notebook-MQ01ABD100/dp/B00AUH3L04/ref=sr_1_4?link for the cloner http://www.amazon.com/Sabrent-External-Duplicator-Function-EC-HDD2/dp/B00IKC14OG/ref=sr_1_1?ie=UTF8&qid=1436744884&sr=8-1&keywords=hdd+cloner |

while the ant miner will draw 355watts on freq 218 or freq 225 that is based on a quality Gold rated psu.
your psu is rated 20 amps per 12 volt rail and 34 amps combined for its two 12volt rails.
If I knew that each pcie wire drew from the separate rail 1 + 2 you may be able to do freq 200. But many times your lower quality psu will use one 12 volt rail for both pcie's and the other 12 volt rail for the motherboard.
I also am pret sure your psu is bronze not gold so it will use 385 watts not 355 watts.
So I am trying to keep you safe by saying try the freq 175 setting not the stock 218 or 225 settings.
If it runs 2 days in a row at freq 175 bump up a little higher.
I mean, so we all clear the real problem is that the network operated 600-650w was what I have (free energy) do not have to pay for it. have HP DPS-800gb (1000w too high) 4x pcie PicI found a buyer and buy another one search _ CX600M  for example i found corsair CMPSU600G Pic good? or FSP Raider 750W PicIf you own 1 S-3+ and you own 1 Hp DPS-800gb you do not need another psu. Attach the s-3 to the HP DPS-800gb the s-3+ will only pull 340 to 370 watts from the HP Dps-800gb |

pools try f2pool it pays every day and gives you some nmc which are pretty high at the moment
Antpool you can turn it on PPS very easily and its fee's are 2.5 percent. Just have to go into settings and change mining type. F2pool is 4 percent for PPS. It is a good pool aswell, but higher priced fees. I suggest go antpool turn to PPS and enjoy the extra 1.5 percent earnings. yeah but f2pool gives very high nmc payouts antpool does not. antpool has luck and variance f2pool does not you always know what you get. If you change antpool from PPLNS to PPS it takes away luck and variance. It makes it the same type, PPS as f2pool. It is interesting on NMC though did not think of that. Do they pay enough NMC to where it equals the extra 1.5 percent your using for their pool over antpool? they give you 7 nmc for 1 btc so if nmc is 0.0036 btc x 7 = 0.0252 which makes up for it. they also give 7 ioc for 1 btc 7 ixc for 1 btc 7 dvc for 1 btc so they are a tiny bit better then antpool . Now I have not mined with antpool in weeks are you sure they let you switch from pplns to pps at no extra charge? |
