The downward trend has now flattened with Yesterday being +7.6% 155 Blocks. Run rate for the period is now +13.27% and looks like it will run flat at this rate until the end of the Period.
Rich
People in S7 thread have been notified on shipping on some of them it sounds like on batch 10. I still think part of the downward trend is just gear switching locations. Seems like big and small buyers of Bitmain getting S7's after holiday's there. not sure if it is whole amount though as I agree that would be a lot of S7's. But none the less it has to be part of the downward trend. If I'm right it will go back up pretty soon, but I could be wrong  . I would like to be in this case. |

Because any gear that isn't running at 0.25W/ghash or less is no longer producing and profit and after the next diff change in the next 24 hours it will certainly be at a loss. There was an estimated 400 petahash of gear that should be shutting down over the next couple months. Looks like about half of it has just turned off. That or network variance. However considering that build out of new gear is still happening and hash rate is going down perhaps variance can't account for a decrease. Either way .. mining with anything but the S7, the latest Avalon and BW.com's 14nm miner thing will effectively cost more than it will mine even with fairly cheap power.
Thats just wrong. S5's are still 50%~ profitable on 0.06$/kWh which is not great but not bad either. This is around what you get if you have your things hosted in non rip off data centers. Right now i break even on S1's. The S3+ will be running for a bit longer still. What data centers are you getting .06 from? That is lower then most out there that I have seen actually. I know one that is a little above .07 that brags a lot about being one of the lowest. I think you will find more are closer to 8-10 cent area. And I agree it should be cheaper but they are not in most cases. |

Help guys, I have 2 U3 antminer, 1 I bought from china, the other I got in my country. The chinese one came with original power supply conected to pc and tried on raspeberry pi 2, both with no success. Chinese from start didn't work, got steady light at led and tf1 (leds), sometimes rf1 blinks once and stops, cgminer doesn't detect u3, but windows does I followed instructions and used au3-freq 225 au3-volt 750, as described as default for the miner. Chinese seller did extensive test over teamview an decided to send a new board.
It took 60days for the u3 to come, so more 60days with a new paper weigth, I got angry just tinking about it and bought another U3 in my country to mine while the board doesn't arive.
The new u3was the same model, I did the same config, worked for 1 day and stopped working. Now I only get a steady light at led, and rf1 blinks once no other.
Can any one help me understand or maybe fix, if its fixable?
Are you using same power supply? Do the two share any part's. To have 2 dud's from different sources is unlikely. I'm guessing there is a shared issue. And I could be wrong but look at what the two share. With windows Zadig can sometimes give problems. So might look into driver. With RPI though I would try more with it. What issues did you run into with RPI? |

I would not invest in cloud mining anymore like I used to before I found the truths about them. Seems they would be YHIPs. No more. Just letting one cloud mining
account just run its course until they crash. Then, O WELL! That was an older account. I THINK it is Zetacoin that I was accumulating from there and I think it was
ghosted by me, mentally until the last day or two to recover it and pick up a wallet as I formatted my computer. Using backed up wallet for it so I put the wallet.dat
file in and getting it synched again.
I see you have never used my Ucloudmining... try it for free or invest 0.001 or more and you will change your ming. The problem is there though. Even in numbers you released: Total accounts:212 accounts. Total claimed for free:0.00746222 BTC Total invested:0.36640338 BTC Total pending investment:0.3315961577 BTC Total pending payout:0.0115563416 BTC Total payout:0.04682193 BTC Number of buying:1292 times Number of selling:16 times. Number of re-invest:4 times. Selling bonus:82% Claiming bonus:1.01547987616% Re-invest bonus:100.923076923% Compare invested vs payout. With a few U2's you are not going to mine the invested amount... you just are not does not compute. So I think your own numbers are what put final nail in your u2 cloud. |

Based off of BTCS own numbers, it costs them $125,870 per month to run their 1.8Ph/s.
At current difficulty (144,116,447,847) and price ($419/BTC), they make ~44 BTC per week, or ~$18.5k per week. So they are completely in the RED on operations or have shut down, aka, no revenue.
They've also stated that these operational numbers were gross, so they probably do not take into account personnel and other ancillary costs.
I love that this company is public we get to see inside which most we don't. With others keeping private we will likely never see info like we do with SP. It is interesting to say the least. I don't see how they are going for different market then Bitfury though from Dogies pic. I think SP and Bitfury will be fighting for the same big operations. And bitfury threw a heck of a punch with demos of chip already, and beating SP50 specs. I think SP has a hard time coming up. Biggest chance i see is if they can beat bitfury on price. And we have no idea what that price is right now. I'm still wondering if they are making SP50 or call it a sunk cost. Seems hard to justify when you know your chip is already beat. How it's been same rendering for so long I think sunk cost is more and more likely. |

Hi guys.
Here is the last status from Hash Coins, they are providing me a mining contract for one year only instead of my order. This contract is against my free will, I didn`t order it. Hashcoins didn`t offer me a refund , eventhough I asked them several times. By a simple math it is clear there is no chance to get already paid BTC amount back in one year, coz maintenance fees are approximately 75% of mined amount now. If someone start a lawsuit, I would be interested to connect.
Their status :
"To our greatest regret, we are forced to state that will not be able to physically devliver your order.
The statement above does not indicate that we are forfeiting our obligations to you as our customer.
As compensation, we have offered you the only currently available solution: a remote mining contract that will allow you to get your pre-payment back.
Attached is an invoice that confirms the Remote Mining Contract with you that substitutes your initial order at no additional cost for you.
Once again, we apologize for this situation and for all the inconveniences this has caused you.
Best regards,

You can't say you are surprised they were scammy about pretty much on all miners. They only made ones they shared chips with others. What is the cost's and power on the "remote mining contract"? Is it like the Uranus on the deal? Or worse? But I would not even count of them having miners. It would not surprise me if they say they mined for you and just send part of your payment back, eventually with them keeping the rest. Sadly it's easy for cloud companies to fake mining. I hope you did not get taken for too much. |

I literally can only think the only way of breaking even and making profit in a year is to get a business grant, which is non re-payable for a business start up, using that to buy second hand S1's or S5's on Ebay and then installing solar panels for summer and wind turbines for Winter. That's ASSUMING you get full electricity provided by the renewable energy devices and assuming you are not renting the land/property to do it. You would then make approximately 20% profit. hahahahaha. I would consider it, but my dad won't let me put the solar panels on his roof!  what a chode!!!!!! Solar is to expensive though in most cases. Look at the price and how it's a drop in the bucket for some hobby miners. It's just hard to have a lot of watt's of gear let's say even 10k watts.... you have quite the investment in solar. And this not a quick investment your talking 10+ years likely to pay off if everything runs right. Which is very long term compared to bitcoin mining. Some will do solar yes... but that initial cost is hard to do. Compare it to cheap electricity those with very cheap electricity almost always win. |

S7 prices are getting lower per batch due to the increase difficulty and upcoming halving. Best to check the difficulty stats since once the older miners are being outgunned then difficulty increase could head towards the opposite trend making S7 mining profitable again but still there are so many uncertainties compared to 1 year ago.
To be fair there are always uncertainties. Even during day's I ran Dragon 1T's on asics, it was will I make ROI.... when will next better miner come out. And the S3 came out eventually beatting the A1's by a decent amount. So there is always the next gen possible uncertainties. And value is always been uncertain I mean I can remember when close to 1K was considered normal... and now if you bought at 800-900 you might have lost 1/2 of investment in a year. So that is another example of uncertainties are nothing new. Miners get cheaper as the difficulty changes. So I think it's more of the same old thing for a lot of it. |

I am surprised to be honest some of first batches did not get some decent coupons. It seems bitmain has changed for mindset of giving out coupons of good value to make up for it.
Just like batch 10 it's going to drop a decent amount again when batch 11 goes up I think. With difficulty changing so much it's hard to do pricing on gear. If the price drops more then you mine... kinda stinks as a miner. We live in interesting times that is for sure.
There were coupons for Batch 1 - but they were so short-lived that a lot of us COULD NOT come up with enough money to actually USE the damned things, especially when the S7 showed up with such short warning as it did. I don't remember what the amount was but S5+ users also got coupons they were decent. I sold half and gave half away. Giving some away made me feel better as i had gotten coupons before. It seems now day's it's all about selling them. Also it is surprising how low last coupon was. I think around 20 dollars or so? So not really much at all. And the hard part I see is difficulty changes the miner should be having decent price drops if difficulty changes. Don't know if companies will follow or not. But 20 one week, then maybe 12-13 this week is a ton. Miners essentially lost 33 or more percent of earnings in two difficulty changes.... that is a bad number. But it get's worse Include the 5.8, and 9.12 before that we since January 13 we likely are talking about 47+ percent change. We almost halved in a little over a month. So I see mining gear as kinda hard right now unless we see some serious drops. Which to be fair there have been drops in prices just not to that extent I don't think. |

With all the changes I started some new ROI spreadsheets. My ones from a few month's ago seem to optomistic with difficulty changing so much.
I had not added up till today the past year's electricity. I was focused on month to month (as my gear channges buy new get rid of older). Only thing for sure i my new set of ROI spreadsheets is the electric company must love me.
I think the realistic difficulty rise should be at least 15% for the next 6 months. The 16 nm miner will increase the hash quite a lot. We have no idea what it will do. 15 percent each change is a heck of a lot more then we were doing most of last year - https://bitcoinwisdom.com/bitcoin/difficulty . Really since November we had crappy numbers for a lot of it. I'm not sure you can blame right now on 16 nm, it just as easily could be bitmain with current chips. But yes once 16nm hit the shelves in data centers they will do it fast. It's hard to tell how bad it will get. Our main hope is if bitcoin has a big value increase were getting a little bit but not enough in my opinion. But I think this post is getting off track as it was talking about consumption. Right now compumption is a lot on last gen gear with normal electricity prices. I sold all my last gen gear and bought coin's. I was just not making enough to be worth it. It will go into buying more miners not for sure yet if I want more of current or wait.... I'm torn but I do feel good about selling now on last gen. |

Xapo is the best i think, not for many bitcoins but for small and daily transactions its the best, because it has no fees on transactions.
But for me xapo is the worst online wallet for me i can't login there fast after 2 factor authentic they send the code to my number but it take long time to receive your verification code.. its better to use coinbase or blockchain as online wallet than that wallet.. Then just download xapo app for your phone as the code will be sent to your app rather than your phone number and it's faster that way  Dont use blockchain as their security is a trash overall My wallet got hacked twice and yesterday i got an email regarding login attempt even though i havent open it in a months  I don't see how you are getting hacked so easily. I think it's likely you causing it not blockchain. Do you have 2 factor turned on with it? You can go pretty deep with 2FA where even if they have a password it does no good without the 2fa item. So not sure how you got hacked twice if doing that. Also they would need to know wallet it... which it seems you would provide through compromised device or phising. So I don't think you can blame them. Yes, to quick to blame a wallet when the problem is his own security measures or should we say lack of. It is just a day to day wallet and the most that could be stolen is a day)weeks spending so it is really not a big deal to leave a couple of btc on there. I feel bad for the ones who get wallets compromised. But we are in agreement a lot jump to something like "blockchain is crap I got hacked" etc. It is not the wallets fault in most cases of compromised computer. You most likely got infected somewhere else. Once your compromised all data is open, if you keep private key on commuter (horrible idea) the BTC can be taken easily. On sites that offer 2FA use it. I cannot fiigure out why every single blockchain account does not use 2FA, it does so much good. I still am playing with Yubikey's and they work great with it. For not a ton of cost you can have a much more secure hot wallet. And ofcourse there are paper and hardware wallets that both do have a place and use. |

My trouble starts with this simple problem. Without getting the miner to that ip, it will NOT connect to the internet, meaning I won't be able to access the config page. myminer.io forwards to start.spondoolies-tech.com, while connected to the internet, When I setup my antminer S3, I could locally connect the miner straight to my computer to the miner via Ethernet. Can I do this with the sp20? when connected to the sp20 on 192.168.1.1 [http://imgur.com/OoUwtHR pic here I can't explain it, and go to myminer.io, nothing shows up obviously cause the dns won't work. Now I know I need to find the actual ip the miner is communicating on, but I have tried nmap and netscan to no avail. If I reflash the firmware, will the miner go on a default ip and then I can communicate with it, or will that not work. Thanks I kinda see two different questions. Should you be able to connect to a computer and share connection? Yes if you set the right settings you should. I'm kinda reading between the lines here but is IP address of miner different then your router? Or what is reason you wan't to do this? If it's different you could connect to computer and switch IP address to router range. I personally would go direct to router instead of going through a computer unless that is only option. |

Is it compatible with Raspberyy Pi? I saw a Bitfury red fury being used with one, hence me asking.
Thanks.
As said above yes it does. There is install instructions on page 3 that I believe work with RPI (been a while since I had to set mine up). If you get a good hub it can be a very good miner and a great combination with RPI running them. |

Yes 2 - 2.5TH / Board sounds about right. Much as I like the simplicity and efficiency of String designs it is actually quite nice that this is a Conventional Buck Converter based unit, could make for a more reliable unit with undervolting being easier. Also I suspect that the added component cost is quite small and with Miner pricing not seeming to be based off cost it may have very little influence on the selling price.
Rich
Well your look at LEAST 100 bucks in component costs for the buck design in this board. Let say they sell the chip half of what bitfury is so around $5 that will be ~300 bucks, so I can't see them selling this below 400 per 2.5 TH. well maybe I will get one some day. but no links for purchase so once again oh well. A 5 th 400 - 450 watt unit would be nice to own. I'm guessing BW get's internal put in first before us little guy's get a chance at buying. It would make sense as them to want to get as much as they can before having. And it's hard to say how much of these they will do for internal mining they sold a LOT of cloud so should have a good amount set for this. The good news is i do think it's a miner we will all be able to own and I agree love the specs as of today. I just think it will be a while for us to be able to buy one. |

Why scam?
2 reasons it is likely a scam: 1- Do you have an arrangement with Bitfury to get the chips? If so could you please post some evidence you are getting the chips. Also, I have received an email from Bitfury that states they are monitoring for scams. I am sure they will chime in on this thread when they see it. 2- There are a lot of people on this forum that have a TON of experience and a TON of trust and they are not getting chips, how is it that a noob shows up with no history claiming to be able to make a miner with Bitfury Chips. Now, if you are getting the chips I am sure you have a website that is associated with Bitcoin, could you link your credentials and the website. Thanks Also it seems your account is 2 years old and you were trying to be a retailer a year or so ago. Are you still retailing miners in the Ukraine? Also, I am not sure how shipping would be coming from the Ukraine but I would bet it is not cheap. I will ask Bitfury if they have any partners in the Ukraine I have a rule never buy from rendering.... and this is pre-rendering even on gear. So it throws huge red flags up. And it is on a new account.... again more red flags. The truth of the matter is new manufactuers are hard to find, we have if anything gotten smaller and smaller on amount who make miners. And this is likely to continue. I would not order this gear. I do think it's likely a troll though and not a scam. |

Wait for the 16nm Chips..
Wait for how long? What will price be on these? Will smaller miners have to wait for a while to actually get them after big operations? And how close to having do we have to wait till? So many questions and no answers. Waiting till 16nm sounds good but in reality there is just to much unknown to say what is best. And really some people are always waiting on the next gen, and they never seem to buy. |

I've never understood how losing money can be enjoyable.
(I don't class "spending money on doing something FUN" as losing money).
Prior to bitcoin many thousands of people the world over happily contributed cpu and gpu power for distributed computing projects just for the fun of it. Some of those projects still exist though they're not as popular these days. It's a new phenomenon thanks to bitcoin that people suddenly think their computer hardware should be making money for them. I agree completely. For some people (like me  ) in this world, things involving computers and data crunching and 24/7 psu running is just very fascinating. I can't go inside people's heads, though, so I assume there are people like me out there. There is a point thought you most cannot do. I consider myself a hobby miner. I see it as a step above home miners. I have a area just for mining and it is not cheap on electricity. If I lose money it add's up and I could lose a lot. I had to get rid of old generations of gear as I was getting close to losing money on running some. I did some math and selling and buying BTC and buying more efficient miners made a lot more sense for my operation. So I still will be using it for mining most likely. I will always mine but I think we will find a lot that will not be able to mine as profitable as they once were unless some major things change. I can't lose a lot of money for a hobby no matter how much I love it. I can lose some and go smaller, but again it will be smaller. |

Coming into the home stretch here, looks like it'll be right around 10% increase by the re-target. I was way off lol but its hard to predict far in advance like I did.
It is going down that is for sure: Bitcoin Difficulty: 144,116,447,847 Estimated Next Difficulty: 163,916,409,052 (+13.74%) Adjust time: After 211 Blocks, About 1.3 days I thought for sure we would be in the 20's. I still wonder if shipping of S7's for batch 10 has anything to do with it would temporarily reduce hashing as they move centers. Big guy's in mining like PCFLI are getting shipment after the holiday that ended: https://bitcointalk.org/index.php?topic=1283287.msg13860532#msg13860532And if there are more like him it's hard to tell how many sales as I suspect it is a lot with big volume sales, and regular smaller buyers of batch 10. |

I'm not too concerned about power cost as most of my miners will be ran with solar power during the day and standard electricity at night with battery backup during the switchovers.
Doesnt that mean you pay electricity half the time? My solar panels are generating 475kw/hr give or take, bear in mind that the battery backup is charges throughout the day and will run off that until it gets to 25% and then switch to the power grid. I'm not worried about exceeding my generated power any time soon Woah isn't 475kw/hr like a lot of electric, I may be way off but I know 1,000Watts equals to 1 Kilowatt so you are saying you are making 475,000 watts per hour ? What do you have like a whole solar farm lol That is a heck of a lot of electricity I believe doing math in my head to. OP do you have like a solar farm? How big is your operation? If truly that many watts yes you can have quite the operation on mining. You will have some costs though building your mining area. To have it all wired up, proper cooling, PSU's, etc it adds up but luckily a lot of these are one time costs. If you have all this power there will be a LOT of one generation old gear for pretty great prices. Or there is current gen that will have the most resell value but also costs the most. |

One we don't really know on is some old spot's PCFLI ran miners in: https://bitcointalk.org/index.php?topic=514758.0I know all of his current group buys go into a really nice center. But these old "simple" ones I would guess someone else if not him is using. Can't imagine building farms and then leaving them. This is just a example I figure there are a few players with "simple' data centers that are pretty hard to track. And this is all speculation I have no idea who owns the simple ones now. |
