I think more profitable trading than mining. I am sorry if i am wrong  It all depends there is no one size fit's all on most profitable. To many variables to make one case best for all. And there is lots of kinds of trading. That is pretty vague. |

LMAO, look at one of my older posts, I knew for a fact this facility would overheat based on what I saw... Little do these guys realize, you need about 150cfm per KW of airflow... That facility @ 1.2mw does not have a 275,000+ cfm worth of airflow through 36'' ducts...
What a joke, the concrete structure makes it a heat trap / chimney. The white smoke test they did took several minutes to clear out... We fully cycle our air from intake to exhaust every 6 seconds... Yeah, so a white smoke test in a properly designed facility @ 100cfm per square foot vacating air allows you to keep your units cool. And the smoke test, would simply flow from intake, through exhaust, and be 100% clear in less than 10 seconds..
These guys are attempting to condition air, and not move enough of it, leaving them with massive hotspots, and expensive PUE, and a horribly inefficient system.. The only thing you have is .03c per KW/h compared to china's .04 / .05 cents per KW/h
Can't wait until we go public in some of our assets so everyone understands why they can't compete... I mean, look at Bitfury, they have a facility in Georgia (the country Georgia) directly under a hydro powerplant, paying less than .03c per kw/h, evaporate only, don't have to worry about compressors, and have about 20mw+ of capacity and expanding...
With the changes in heat sink design and methodology as well, you don't even need to treat the air.. You just have to move a lot of air, even if its 90 degrees across the chips rapidly and your fine... At least the direction bitmani is going with there small chip set.
Good luck if you go in this facility.. Why do you think Spoondoolies took one look at the facility and said no way... They decided to go to a different datacenter in Washington and a footprint @ vern global Iceland instead? Bitcoin miners consist of two groups now, large industrial players, and hobbyist, don't expect to make a dime... Its a hobby YOU pay for, not get rich on... You can't compete with my sub 40-50 dollar per KW cost including overhead staffing and cooling... And the fact that in massive orders, we pay about 50% of what normal people pay for equipment from the manufacturers due to large scale contracts.
If you have free power, and live in a cold place, YES! you can make money, these guys can't even make money if they are by themselves building this facility with compressors and attempting to treat air. I'm sure the capital for the contractors they used too was excessive as well, that looks like a very expensive facility that can't even run at 60% of its promised capacity during the hot months... You guys are lucky its cooling down, you'll have 6 months to get your shit together.
We can compete with you and everything is properly cooled and is running on quality infrastructure. You make some great points. We choose to grow slower but build better and still offer the best price. So you're telling me, that you can compete, with my facility, if I were for a significant profit, offer $50.00 per Kw per month hosting once we finish our 5mw expansion for possibly hosting other large clients? FYI, we used remote power switching PDU's, tied into a miner monitoring software that automatically reboots the miners if there is a problem. If the unit doesn't come back up after a failed reboot, then an alert is setup to the NOC and to our guys at the DC for them to work on the unit... We run @ about 99.95% uptime from all our units. Even miners that freeze, or have blades go down every 12 hours still run at about 95-98% efficiency because of our ability to monitor and remote reboot the units... This allows me to reduce the amount of labor costs. Oh also, in an emergency if we loose an evaporate cooler, the system can automatically load shed (turn off the units) before they begin to overheat and cause permanent damage to the ASIC's, an event you had earlier in April... Our goal is to offer mining contracts to people, not host miners, direct, as we can purchase units at 50% of cost wholesale, and actually pass on real profits to individual customers, while still making margins on the hosting and the unit / resell, but offer power rates equivalent to $50 per kw instead of $60, and once cap X is paid off in a couple of years, we will have operation costs in the $30 dollar range with maintenance and personal. What mining company do you have an agreement to get at 50 percent of wholesale? That is a heck of a goal. I would sure be interested if you can get units for close to that.... but I'm not sure I see 50 percent happening. This is also first time I have seen hosting companies argue.... very interesting  It's impressive what a million dollar level purchasing power will get you. Remember, economies of scale, ASIC manufacturers make a lot of profit on the units when they sell to the public. We have NDA's, but its around 50% When will you be able to offer these miners to public at this price? At 50 percent you will find a lot of buyers. |

So Bitmain wants me to flash a new SD card. I think I see an empty SD card holder on the top of the miner? I'm thinking that the miner did not come with an SD card? Should it just be an 8GB card like my Pi?
Posted From bitcointalk.org Android App
Depends on size of firmware. I imagine an 8 gb would work. What is the size of the firmware. Is this still all about not being able to set static IP? |

In my opinion there is bad news & bad news. The bad news is that things are not good at the moment for home miners. Bitmain is the only game in town and their latest releases, although good, are expensive and very unlikely to ROI with the way difficulty is increasing and with halving coming up fast. The other bad news is that the more time that passes the worse things are going to get.  Rich I think home mining will be profitable again only if Bitcoin price will skyrocket, am I wrong? If you have very cheap electricity, home mining is fairly profitable. If you have high electricity cost (around 0.1/kWh). It's going to be hard, with the S7 being so expensive. Right now it's all about that electricity price. If you have a good price profit is still in sight. Most places is a long ROI. The game is changing from day's of quick ROI. If BTC would skyrocket it would not hurt. But would also raise miner prices with it likely. |

TY sidehack and novak! came nicely and safely packaged. I'll play with it later tonight!   I like the all green looks pretty sexy. Everything from PCB to heatsink. Thanks for posting closeups of final product. |

Yup, in the Northeast, I pay $0.148 per KwH, but my colo is at $0.10KwH and I have free power available also at a few places if it's not annoyingly loud. Sad part is, 50% of the price of electricity is all BS fees and taxes. UGH Free elec, thats looks nice. Did you try to underclock too so less heat and less loud ? I "use" friends in dorm to put some of my S5s (since its elect-free), and I give them half of elect prices, so I give them $20 for every S5 put in there. With this they wont complain of the noises  I can't imagine them doing this. I did not mine in dorms or student housing. Just was not worth it to me. You have limited electricity so can't put in enough to make a lot and then you have a noise when your doing homework or have people over. Just not worth it. I was always lucky though and had another to mine though. |

I think he is out of touch the each time i read "Mining bitcoin with the router is a long time dream for the Bitcoin miners.". It just makes me wonder if he was not aware the other options to currently do this, or if he really thinks my dream is to mine with an router.
I just keep thinking there is some software that ties it in with another bitmain product most likely antpool, or I still think possibly cloud mining. That is their reason to make them think it will make profit.
I cant wait till more information is know. The more we talk about it the more insane it seems.

Personally i would probably go with something like 2x evga 1000 on one 15a 120v breaker. Flip the power bar switch, both turn on at same time, voltage should be the same (mines are very stable). Plenty of cables.
Great efficiency, the draw put them at optimal load. Meh. A bit expensive but quiet and reliable, 10 years warranty.
I think Bitmain said if they arent powered at the same time, the controller need to be powered last. (Probably because the board don't have any draw until the controller is on).
Only way I would mix is if you are not mixing on hasing boards. If you power entire hashing board from one then yes... should be ok. But if you do mix PSU's on same hashing board it will void warranty if bitmain catches you. |

SFARDS did e-mail me back saying they would have a batch 2 order but no time was given so I wouldn't expect if for a while i noticed LTC difficulty was dropping now its on its way back up so i suspect someone is turning on the lights on some new gear
They have either a big customer or are mining on their own I think. I am not sure which but it's odd for a product to come out and need only 5 units to select resellers. I wonder if eventually they will sell them though. They got the end of ltc having so maybe who ever owns them they will sell and they call it batch 2. I just hope price goes down with ltc having. |

I have a unit on hand now. What is the latest firmware that allow voltage control? I'd want to try that on Kanopool. See if i can get good hashrate and good efficiency.
I don't know the exact one but I believe I had factory default on all of my S4's and had it. It is the early one's that had it. They took it out on later firmwares. I recently got rid of my S4's so can't tell like I would have been able to do. |

Have you experienced loss of power where the miner then starts back up after the power comes back on. Just wondering if its a problem with the hash boards and and controller all coming back online at the same time? The S7 has the same sequence of powering the hash boards then the controller and wonder what will happen when I power my S7 with 2 PSU's and experience a power outage and it comes back on?
Have had loss of power, loss of network. It has had no issues with either. Both caused by a really bad storm luckily only once. I did go out and turn off the power during the storm so it did not have surges or anything, so I guess it did not have a hard restart. But network it did fine on. Power I was a little over protective. |

You'd be looking at under 10GH even with the BM1385. Depends on how much power the entire rest of the device takes. Seems like kind of a waste.
I think you hit the nail on the head. It is a PR thing they for some reason think will help cloud mining I think. They have not released hardly anything but I wonder if they can find a way to tie in cloud mining with it. If they for example have this router have a chip that does almost nothing and shows cloud mining stats. I feel safe saying your compac is a better miner then whatever this ends up being with the router. |

Miningmine some coins at minergate.com, you can mine with any computer. mine BCN, or XMR Can someone explain me hows does that works? I dont get it at all, you can actually mine online without a miner or what? you can mine btc with your normal GPU, but its slow as shit. you won't get enough to pay for the electricity you run. but i believe mine other altcoins isnt that bad but, how much are we talking about? How much Ill be earning if I let it on 24 hours? does take a lot of electricity? I can turn it on in my job (LMAO). GPU mining in most places costs more then you make. Not to mention you chances are going to push your GPU's on higher intensity. Asics have taken over at this point. CPU/GPU day's are just over at this point. And even if you can manage to make a little running a GPU you will never pay off the GPU from mining it. |

with paypal people could scam you even for only $8
Sadly this is true. I would never sell BTC for paypal. The ones that do charge big fees as a lot of issues with paypal. I really suggest saving up and getting a good exchange. You will really like it being able to buy BTC straight from checking account. Much easier and nicer. |

They claim that it has two network interfaces (back & front).
+ WLAN They know what's important. Every miner should have a auto-rotating display yes this is the most funny part of the whole device! Two network interfaces would be nice if you could go from one miner to other. But I'm sure they are just making it all up. I can't imagine anyone who would pre-order something like this. |

Hi guys.. I've been thinking about this a long time ago: Is there any possibility of using an ASIC hardware to work with other algorithms? If this is open-source, maybe you can make a fork, modify and adapt the software-hardware for mining another algorithms. What do you think about that? Is that possible?  I mean .. all ASIC hardware has multiple CPUs-chips and memory that could be recycled. Especially older hardware ASIC They do SHA256 algo. So if an alt of that yes... you could. But no you cant really recycle it into lets say scrypt. But most alt's are not worth mining. BTC is really the most worth while. Older asics normally go to cheaper electricity places until they are worthless. But normally they have multiple owners at this point. |

Is it possible to run the s7 on a 110 based power supply? 1300W or so?
They report it uses "1,210 watts" so likely could run on 110. Only thing is getting a PSU with enough PCIe cords. They kept the S5+ design. So 3 hashing boards x3 PCIe each. So 9 there and then one for controller so 10 PCIe cords. |

That depends on your electricity cost, budget, housing location. Give me/us more information and you will get a recommendation. The S4 isint bad, just the price its listed at is. And unless you're looking for a lottery, you will have to mine in a pool.
Okay I'm living in sweden my electricity cost it 0.08 dollar/kwh I have also 10kwh Solar array my budget are little open depending on what recomendation people give but max 1200 dollars. Internet connection are 100/100 mbit. Something more you need to know? Most likely you would be better off to mine in a pool with the S4. It's not a super efficient miner. I would solo mine with something smaller then 1400 watts. You could do it. But most of us I think would suggest against it. |

Correct. Slapping Sidehack's cgminer(or whoever is doing the coding) on my TpLink is fairly easy and the router already come with USB ports. I could even put a usb hub and run a farm of them on it.
Hence i don't see the point on the AntRouter. It sound gimmicky and also it only mine to antpool. Meh.
I think it's their response to bitfury's lightbulb. They want some item that is for show and fun. Personally I think the lightbulb was a cooler thing as I cannot build that. I just wonder what price will be. If they jack it up to much on router will be funny to see tplink nano + usb miner cheaper. I think they both could be really neat, the light bulb to say a room is full integrated into the network (lights, heat and router). On the subject of the sidehack stick how would you connect it to the tplink directly without a pi? Are you flashing the TPlink firmware? First you have to have the tplink nano with usb. They make one with it and one without it. But you would flash it with custom firmware it is a very capable device. Most went the raspberry pi route, but avalon has used the tplink with their 4.1's using custom firmware. But it's openwrt custom firmware that run's cgminer. I have messed with flashing the TP link with Openwrt for the HEX miner and it was such a pain and unreliable, they may have been due to the part of that miner but I don't think that sounds like a good solution. Mine is already on Openwrt, it was fairly simple. I'm assuming you,re saying compiling the HEX miner was hard? I've not had problem with cgminer before. It worked for many Avalon 4.1 owners. So I'm going to assume was the miner. Don't get me wrong I will probley buy one to play with. But I'm not that impressed with router with chip. Not calling it a "dream" product. |
