What does this mean? How does this affect home miners? Will difficulty shoot up soon due to Bitfury 28nm chips?
The chips are reported to perform at 0.2J/GH, which is a pretty substantial achievement. Once the chip is fully developed / market ready, you can bet all of the big farms will want to incorporate it as soon as possible. It will drive their energy requirements down, allow them to expand, and, as a result, ultimately drive up the difficulty. How long it takes to get to this point, or how high the difficulty will go, is hard to say. I thought from now on Bitfury was only self-mining with their gear.... They also sell wholesale to other farms/ clouds to share revenue splits or contract for hashrate. I know they used to do that, I thought with the new hardware that was no longer the case but perhaps they are... They dont have time to make retail machines but will probably sell their chips in bulk if the price is right. Being first developer with latest gen high efficiency chips give a huge advantage over the competition where they can almost dictate their price because they have invested millions in r and d. dictate their price? with coins at 240-250 usd I am not so sure how fast they will sell. Sell yes, but sell fast not so sure. Now if knc really can do a .06 watt chip in bulk that will sell much better. One thing I do think is growth will get a boost from this. maybe it will do steady 5% vs the 2 to 3% we did from nov. 2014 to now |

so you are doing 760 with meter and 1300 or 760/1300 = .5846 I am 781/1349 = 0.5789 very close. that is about what these do at 1300 gh settings. check your numbers in a ½ day they should stay close to that. then you can go low. .631 .631 .631 .631 .641 max 240 watts 240 watts 240 watts 240 watts reboot at 1000 here is a low miner. around 1120gh  lower watts temps  settings these should let you do 2 miners on 1 evga 1300g2  |

May I ask why will miners still mine after halving happens,as it will be really not profitable then ?
mining seems to never be profitable according to the members of this forum. yet there's lots of people still doing it. i guess they do it knowing they will take a loss. hey I think he should mine. but he never really answered questions that matter. what country and what power 120 or 240 volts. If he is in Kuwait it is very hot and cooling is an issue. If he has 240 volts he could order spondollies sp10's usd they run better on 240 volts s-4's are cheap and make his money back a bit quicker then 6 months. http://zoomhash.com/products/antminer-s4-miner-2-0ths has 2 th for 450 + shipping so 8 for 4400 gives him 16th at his power. at 5% he profits in less then 6 months  at 3% he profits faster  at 8% it takes a while longer  I only wish I had 10k free power for 2 years. |

I got tracking for the new miner. I will look to do a long followup on this as a 2 miner setup very soon.

why not match my settings above exactly make sure you have 1 sp20 on 1 evga 1300 g2.
tell us what you get.
in the first 10 minutes
in the first hour
after 1 day

I keep tweaking but can't seem to get above 1200GH and stay under 700W.
I've increased my volts to .66, max .67, watts at 160. Is it better to increase volts or watts at this point?
okay first step is what does your power cost. If it is under 10 cents higher clocks make sense If it is 15 cents you want low clocks. Second step how many of these machines do you have 2? third step. your volts are 2 high for your watts. if you want 1 machine on 1 evga 1300 g2 do .66 .66 .66 .66 .67 watts 240 240 240 240 look at a machine setup to run alone on an evga 1300 g2  note temps note watts = 833 this is false based on my kill a watt I use 781  settings for this machine  |

white = normal speed
yellow = some under clock
blue = strong under clock

it's pretty much a gamble anyway, whether you're making an early or a late guess. 200% true now for me will be perfect for the diff to not go up at all from this point and max .25% down  isn't .25% interval a bit too big, and restrictive in number of gamblers? maybe .1% is better and also easier  no one is gambling as no one is putting up any coin. It is a free promo. Now if you wanted to charge a fee more players is better. Since it is free if the number was .1 -20 to +20 is 400 players vs 160 players under current rules. It is hard to keep track now. Back to topic we are at https://bitcoinwisdom.com/bitcoin/difficulty (+3.40%)Bitcoin Difficulty: 46,684,376,317 Estimated Next Difficulty: 48,271,445,116 (+3.40%) Adjust time: After 1205 Blocks, About 8.3 days Hashrate(?): 350,555,257 GH/s Block Generation Time(?): 1 block: 9.9 minutes 3 blocks: 29.9 minutes 6 blocks: 59.7 minutes Updated: 9:45 (3.4 minutes ago) http://btc.blockr.io/chartsfeb 22 155 blocks bridges both diff adj ----------------------- 144 is normal 0% feb 23 142 blocks 2 under feb 24 128 blocks 16 under feb 25 161 blocks 17 over feb 26 145 blocks 1 over feb 27 155 blocks 11 over feb 28 141 blocks 3 under 6 full days = 872 normal = 864 we are 0.92 % over if you include part of feb 22 we are around 1.15% I put together a Google sheet that, if I did it right, should track the current day's status live (you might need to go to Tools -> Script Editor -> Run -> currentBlockNumber if the data isn't current, it should then stay live.

my s-5 is right here: I use 375  my numbers my errors are 0.0001 any error of 0.1000 or less is a good number that means 99.9 percent is accepted. or for every 1000 dollars earned you get 999 my hash is 1240gh for 375 that is also good  |

if you pay 0.0005 it is about 12 cents.
I try to pay 0.001 which is about 24 cents.
If btc jumps up to 500 a coin I would pay 0.0005 which would be about 25 cents

SpondooliesTech,
The SP20 is the best home miner I have ever had the pleasure of using.
I'm running 3 SP20's for an average hashrate of 3.3TH with a power draw at the wall measured by kill-a-watt as 1600W.
that brings me down below 0.5W/GH!
It may not be economically feasible for you to continue serving the home market, but you can be guaranteed I'll be a return customer if you make a new miner for us hobbyists!
Thank you for your kind words. Appreciated. Is it possible to have a mining board with removable mining chips (like CPU socket/slot)? It would give you an edge over all other manufactures. I really want to support you against the Chinese manufactures. Good question and this is why I still love you dude. (even with your insane insults) as this would be a nice way to keep the gear up to date. Sooner or later watt per gh will bottom out whether it is .1 or .06 there is a bottom. If we just popped a new chip in every 6 months lost of cost would be gone. |

dac_2020 welcome to the world of BTC. Humphrey Bogart did a great movie Treasure of the Sierra Madre. I sometimes think of that film while I am on this site. Lots of way people will burn you or scam you in the world of btc. But there are a few of us around here that are not that bad. Seriouscoin is the bitcointalk.org version of "Debbie Downer" just more foulmouthed then she is. Here is his lists of posts. https://bitcointalk.org/index.php?action=profile;u=54366;sa=showPostsnasty and negative discouraging |

No, what you really need is a PSU that doesn't use 20AWG wires for its PCIe 6-pins. 16AWG would be quite comfortable drawing that load, and you'll have no trouble finding it on a not-garbage PSU. I'm not trying to be rude, but I assume the one you're using was either fairly old, fairly cheap or both? It probably won't be hard to track down a half-decent PSU with at least 25A on the 12V rail. Look for 80+ Gold rating. I'd recommend a server PSU as an affordable option but the power output is overkill and if you're running R-Boxes you probably want something quiet - which you're not likely to find from server hardware. Fart around in the Computer Hardware sales forum ( https://bitcointalk.org/index.php?board=75.0) and see if anything pops up. I bet some of this guy's stuff ( https://bitcointalk.org/index.php?topic=958566.0) would meet your needs. Its actually a brand new supply, this one to be exact: http://www.thermaltakeusa.com/products-model.aspx?id=c_00002031I do completely agree that I need a heavier gauge wire and that's what the problem is. The actual supply has no issue providing the wattage. I'm going to take a look at the supplied threads and buy something beefier. that psu is a multi rail piece of junk--- for your purposes. http://www.newegg.com/Product/Product.aspx?Item=N82E16817153165&cm_re=tr-500-_-17-153-165-_-Productit has 2x 12volt rails 1 is 17 amps the other is 18 amps that means 1 supplies 17 x 12 = 204 watts max the other one supplies 18 x 12 = 216 watts max grand total of 440 watts max Tell me what state you are in I have a dozen psu's if you are close to NJ shoot me a pm. |

now as for what 10000 watts will earn
antminer s-5's use 600 watts for 1150 gh so 16 is the most you could use.
16 x 1150 = 18400 gh
that will earn about 6800 to 8777 to 10500 usd in a year. 8% growth rate it will earn 6800 5% growth rate it will earn 8777 3% growth rate it will earn 10500 of course you need 16 antminer s-5's and the psu's to run them and that will cost money |

Looks like Asicminer killed off their cloud hashing today, leaving everyone who purchased their cloud hashing product with severe losses after only a couple months. We've seen this story time and again. Customers getting fleeced by overzealous cloud mining operations. Very sad that this appears to be the new business model for manufacturers.
yeah I gave up on cloud mining a while back. glad i did. |

yeah sidehack is correct https://bitcointalk.org/index.php?topic=958566.0that seller has 1-Corsair TX850M: This thing has been my workhorse, used since I started mining with no issues or downtime. $50 1-Corsair CX750M: Barely Used, was used for an ANT S1 for a month. Most Cables included. $50 1-EVGA 650G: Like new, in box, most if not all cables included $30 they are all good deals and will run your gear |
