My opinion is look into hosting not cloud mining. Cloud mining is just so hard to prove not a scam. It will be very hard to get your first customers, you will need to take time and get a good name in hosting.
On cooling it's all about airflow you want to have air coming in and going out. The setup varies GREATLY depending on size of building, amount of machines, and more. There is just a lot of variables in it.

I assume that, when all of us first heard of bitcoins and started reading about it, all of us made our first few satoshis on some faucet like freebitco.in or any other, and everything was like "I'm gonna make so much bitcoins with this!". But when you use if for some time and get a little bit more into bitcoin, you'll see that that amount you've collected over a week or so, is barely worth a penny.
So here's the advice, when you first come here and read all about them faucets, don't get your hopes up (like I did) thinking you will make something out of it. Owners of those faucets are the only ones who will profit. Faucets are there just in the beginning to help you see what it's like to receive, own, send bitcoins and how to use your wallet.
Use the faucets, see how it feels to have bitcoins but don't expect anything more than that.
This is what I do when I know bitcoin, yeah faucet is worth a penny and wasting time, after I earn some penny from faucet I invest to cm and now I know most all of cm is ponziii  There are two kinds of people who actually make money on faucets. The biggest is the faucer owner, he's making money on every single person. Second is the referral magicians that some how get a lot of people to use their referral. (There are not many of the referrals that make good money.) It's pretty much the owner. The only thing I was surprised on is signature campaigns. If you are a decent rank you can make more with it then you would using a faucet all month long. I wish I would have done signature campaigns long ago but i started only in Sr. Member status doing it. |

Glad it worked. Best advice is make sure to include fee that is a easy thing to forget depending on wallet.

Two main things I can think of. One you can easily see what miner needs reset if speed is slower then normal. Other you can set difficulty to most optimized setting depending on pool.

So when batches are sold to the public, the oldest miners are shipped and newly manufactured miners are put in there place. Voila! No hashrate spike... just steady growth as newer, more efficient miners take the place of old gear.
Sounds plausible, works just like a regular shipping warehouse, only with all the stuff plugged in. Warm an cozy too  Honestly it's all speculation. I could make up possibilities of old miners being sold and replaced with more efficient and more powerful miners, but as far as what's happening most operations are pretty quiet. The good news... looks like under 9 percent change. Considering we were looking at some estimates much higher I consider it not to bad. Hopefully week after is lower though. Bitcoin Difficulty: 40,640,955,017 Estimated Next Difficulty: 44,177,958,509 (+8.70%) Adjust time: After 386 Blocks, About 2.5 days Hashrate(?): 291,712,236 GH/s |

More installation guide than review. After only a few weeks this is the most "reviewed" miner since KNC's first batch.
So unless you are just posting to the check the box, so to speak, give us something new. Mods?, Noise reduction, etc.
It's only my first day with the miner:). As far as noise, with having a mining area I do not worry about noise. it is not an issue for me personally. On fan mod so far I do not need one. Again with running it in a separate mining area I am using the winter air and more box fan types to regulate my temperature. So the 2nd fan mod is a moot point for me as well. Is there anything else you would like to know or see besides fan mods? I am running it easy for the first day. I want to see it run at default speed before changing frequency on much of an overclock. As far as what I have planned to be coming are: It will be tried on multiple frequencies and what hash power and watts used for the different frequencies. Also to come is to try and show the Miner Link. |

Reserved for testing frequency's and Miner Link(Not released yet will test after release).

Bitmain Antminer S5 - Review 0) General information + Hardware Needed1) Unpacking2) The Miner3) Install4) Conclusion0) General Information + Hardware NeededThe S5 is going to get you hashing power with a impressively low electric useage. It is a newly designed miner with using the BM1384 chip. It will have a noticeable change in look from it's S3 counterpart. It's weight is noticeably lighter with this new case design. At it's default frequency it achieved the advertised speed of 1155 GH/s ±5% without any adjustment. Additional hardware needed - Standard power supply with 4 PCI-E 6 Pin adapters (I personally used a RM1000 as I had it laying around. You could easily use much smaller PSU and use 2 PCI-E cables.)
- Computer to set initial pool and configuration settings
- Network cables - 1 network cable to go to your network
1) UnpackingThe shipping was very quick right around 2 day's in shipment to my doorstep. Upon opening you will notice it is very well pack in the box with the air filled plastic tubes. It does a very good job protecting the miner during shipping. Bitmain did a amazing job in this area. 2) The MinerBelow are images to showcase the miner. 3) InstallIt was a easy and quick install. You will need to install the 4 PCI-e cables to a proper power supply for your settings(Could use 2, but i prefer 4). I am using a RM1000 PSU. This is overkill you can use a smaller psu with it only using approx 580 watts. Next use that network cable to connect your miner to your network. It will connect automatically using DHCP. It is actually very easy to find your IP using the findyourminer tool. After that log in and enter your pool information and your done! Below is the findyourminer tool which makes it extremly easy to find your IP even with DHCP being used. 4) ConclusionThe S5 comes in as a great new miner to add to your collection. It preformed as advertised without having to do any tweaking. Great miner for it's low electricity usage with still packing a punch in area of hashing speed. For me having my mining area sound is not a problem as it is specifically for mining. Also with winter I am using cool air from outside to help cool all my miners including the S5. In my opinion they took the well tested S3 design and added to it. The addition of tool's' to see the DHCP was nice software to use. I will in future test some different frequency's and see effect as well as trying the Miner Link addition. I want to thank Bitmain for a great product and chance to review it. I am happy to try to answer questions if you have some. |

How do I start making bitcoins with a wallet?
Look into safe wallets. Cold storage or paper wallets. Shameless plug I am in a signature campaign with a physical wallet you can put your paper wallet in and then store it some place safe. On your question on getting bitcoins. You really need to buy or mine. Those are the two main ways. Faucets and things like them will take a longtime. Signature campaigns can be fun as well. Quite honestly a good signature campaign will beat your earnings by far of using faucets. |

4) the spike could be the 24-72hr testing of bitmain or SP-T hardware before it ships to customers. not likely, but it could account for 5-10PH swings as stuff is plugged in, setup, tested, turned off, then boxed to ship and the cycle repeats for another batch.
No manufacturer has the infrastructure to handle 5-10PHs just sitting around idle and only use it for testing. If they have that kind of capacity, they're using it 24/7/365. Bitmain has a large facility that could handle several PH - and its pretty likely that they test the S5 units (even briefly) before shipping them. similarly, SP-T has been shipping thousands of the SP20 unit, and likely performs some testing before its boxed and shipped. there is usually some big varience swings in the difficulty calculations, but i think theres also smaller ripples caused by manufacturers bringing several hundred units online for testing, running them overnight, then shutting them down to ship a day or two later. I would agree I bet Bitmain and SP both have the capability to test units before shipping out. Also they make in batches so I would guess they plug it in till time of sale. It is not practical to make it and pack away in a box till it is bought. That is all guessing though. Bitwisdom keeps looking a little better each day. Looks like hopefully under 10 percent change at this point: Bitcoin Difficulty: 40,640,955,017 Estimated Next Difficulty: 44,652,760,104 (+9.87%) Adjust time: After 450 Blocks, About 2.9 days Hashrate(?): 301,808,962 GH/s Block Generation Time(?): 1 block: 9.3 minutes 3 blocks: 27.8 minutes 6 blocks: 55.6 minutes |

Hi all,
My C1's pump broke, no worky...
is there any place in the US where to buy a replacement? i know syscooling carries it, but it seems to be sent from China...
anyone found a replacement that can be used? thanks
While you searching for replacements in USA,you could contact us to ask for RMA,please send emails to watercooling@ysun.net with pictures or short video. My friend that ordered for both of us sent emails to you guys, but said he got no response when sending the email for the RMA. What can we do? Send pictures of it to the email listed. They might want video depending. Keep in mind time differences with company in China. If I were you I would send the email and if you don't hear back post here and you will get an answer. (Include when email was sent, pics, etc). I hope it goes smoother for you. |

Are their any recovery SD images like the ones SP provides that would allow you to recover your BBB in the event you can't communicate with it or it gets damaged and you need to replace it? I don't believe so, later S5s won't even have an SD card slot. That's unfortunate since the BBB is essentially off the shelf. It would save a bunch of time if people could just swap the BBB instead of having to send the thing back to Bitmain. Amazingly quick shipping as always. If there is not a image I can upload one soon. (It appears I jumped the gun no SD card to backup) I was busy and didn't get to do all I was wanting just some initial pictures. |

[quote author=notlist3d link=topic=909473.msg10083862#msg10083862 date=1420745957
The thing about the "big" companies and big data centers is they have cheap electricity (for the most part). Their profitable period will be more then a lot of individuals simply because of electricity price.
I agree with philipma1957 that they go pretty quick once not profitable. They will try to sell off old stock get what money they can, and then put in new equipment. They don't run for a loss. They might not get it done in a day but in a matter of weeks. I know of one that the electricity was two high for Dragons at a data center, and they trucked it all to a place with much cheaper costs. Been a while but took around a week to get it all done and set up. (This was a while back at this point I doubt they would move again but be unplugged and sold.
My point is that in virtually all cases mentioned above, the "Data Center" (or Philip) then SELL the mining device to someone else. The person (or company) that bought it then fires it right up again, after the shipping delay. So while the device moved, it didn't actually leave the network. Maybe the purchaser didn't make a good choice, but they didn't buy it with the intent of scrapping it when it arrived. So while S3's will be leaving various places, in most cases, they come back to life somewhere else. The total network hash rate didn't change because they left a big mining company. This "rotation" of gear doesn't do one whit to reduce, or even slow down, the rise in difficulty. The hash rate continued to grow. The only time it changes is when those folks still running a Jalapeno, or BL Single, or whatever turn it off and leave it off (or scrap/destroy it). It why I don't strongly disagree. Still there is a mix of : sell off the s-3 to a low power guy. the s-3 dies and gives up the ghost. The s-3 simply is turned off . The s-3 is most likely close to ⅓ of the network. at least ¼ The s-1 was about 1/5 the network. The network started a slowdown in growth from the s-1 to s-3 conversion. as the s-1's slowly stopped running. The s-3's will not all be sent to 3 cent a kwatt data centers. Some will be used by the little guy as a winter space heater they are a great space heater . If you were already going to use a space heater you may as well use an s-3. I still see the s-3 slowing growth over the next 3-5 months. To what degree we need only wait to see. [/quote] There are a mix of S2's and Dragons aswell. They eventually be obsolete. I expect the data centers to try to sell them at what price hard to tell. Or they can run them till it's no longer worth while and upgrade. Sometimes selling is not worth it at very end of miners life. |

I think there is a pretty long latency from when a miner stops being "economically viable" to when it is actually taken off the network, and not returned later because it was sold. A sale from "Big Mining Company" to "Home Miner #2967" doesn't do anything but inject a short term drop, since "Home Miner #2967" will mine with the device for a while. Even if he made a poor choice, nobody buys a miner in order to not run it when it arrives (excluding BFL pre-order victims).
I'll bet it actually takes months, before a device leaves the network, and is scrapped. Certainly way longer than a difficulty jump or two and a few more spasms in the price of Bitcoin.
Disagree but not strongly. I have run losing miners for a few weeks hoping for a price jump in the coin. But price went from 350 to 280 and diff looks to be jumping hard. So At 18cent kwatts in europe to 25 cents kwatt in europe that drop from 350 to 280 hurt a lot of gear the 40 to 44 jump in a few days will hurt those miners more. At 18 cents a kwatt and 350 usd coin price diff of 40 you make .79 cents a day on 2 miners at 18 cents a kwatt and 286 usd coin price diff of 45 you lose .29 cents a day on 2 miners. yeah you have 2 miners you say fuck it I will run them and hope for a price in coin jump. If you are me and have 12 to 20 you turn them off sell them and buy some s-5's sp20's or you use the sales money to buy and hold a coin or 2. There are a lot of s-3 miners and they are now faced with. Do I run them at a loss ? Do I sell them off take what I can get? Starting next jump s-3 miners will begin to shut off gear. Here and there but not every where. The thing about the "big" companies and big data centers is they have cheap electricity (for the most part). Their profitable period will be more then a lot of individuals simply because of electricity price. I agree with philipma1957 that they go pretty quick once not profitable. They will try to sell off old stock get what money they can, and then put in new equipment. They don't run for a loss. They might not get it done in a day but in a matter of weeks.

Hi guys,
Bit of a problem - I have 2 x SP20E's that have been running the latest firmware without issue. I had to switch all my stuff off while an electrician was doing some upgrade work, but when I switched everything back on again the two SP20's were nowhere to be seen. My router doesn't see them, IPscanner doesn't see them & I can't ping them. The fans are running but they're not hashing, the ethernet LED's are flashing like they're working - but they seem to have completely disappeared off my network. It's like they've "forgotten" everything. I also had my router set to reserve an IP address for them, which worked perfectly up until now.
This is the first time I've had to turn them off with this firmware installed - could it be a bug?
Any suggestions will be gratefully received......
Are you able to see them on " http://myminer.io/" ? If working properly they should nicely be showing there. If truly nothing finds them there is always recovery through SD image. |

Those are water fountain / fish tank pumps which do work, but have half the pushing power and height as the C1 rated pump. They also have no reservoir, unless you have that pump sitting inside a small bucket of coolant or something? From the specs that one is rated around 1/2 of volume pushed. I would guess it's partially based on ambient temperature. If OP has very cold ambient it will cool the coolant when in the tube, not just in the radiator. Personally I would not go this route but I know a few through this thread have. You would use anything that holds water and is big enough to put it in as a reservoir. Reservoir's are not really anything special. |

happy with the miner reporting on pools. this one is guild. showing very accurate
top - sp35
3 x sp20
bottom - sp31
(saving space)
Thanks for sharing beautiful to see almost 6T from a single unit. |

Well it's not great news but still good news. The bitwisdom is going down as some suggested.
Bitcoin Difficulty: 40,640,955,017
Estimated Next Difficulty: 44,858,226,258 (+10.38%)
Adjust time: After 620 Blocks, About 4.0 days
Hashrate(?): 301,303,498 GH/s
So still much better then the 14-15 percent change it could have been. Hopefully we can be under 10 in 4 days... we will see.

Hello all, I've been following this thread since page 40 and I need your help.
I bought an Antminer C1 a couple of weeks ago and after changing it to a new location and internet I'm still trying to access it through 192.168.1.99. I had already set it to DHCP at my previous location and it worked fine; it mined for about 20hours.
Here at the new location at first I could see that my router had assigned 192.168.1.101 to the Antminer so I was able to access it through that direction but it wouldn't mine; so I changed it to Static (without writing ANYTHING, no numbers at all on the spaces below "Static") and clicked "Save and Apply" in order to change it again to DHCP afterwards hoping that it would reset the connection of DHCP and star mining.
After that I've been unable to find it using 192.168.1.99 nor 192.168.1.101 (previously assigned) and I have even tried 192.168.1.199 but nothing works. I downloaded a program to scan every device on the net and see its direction but the Antminer does not appear listed. I've also tried to connect to the miner directly with an ethernet cable to my PC but it can't find anything at 192.168.1.99. (even changing the 192.168.1.1 thing on control panel and the properties blabla) I've tried to reset it using the button on top of the ethernet connection but it seems NOT to work, I've tried many times with 3s, 5s, 10s, even 90seconds and nothing, it does not even produce a sound or change of light.
What can I do to connect to my miner?? I would greatly appreciate any help you could provide me, thank you very much in advance.
Did you change netmask, gateway, and dns to proper entries? (You can use ipconfig on PC to get what to put in them) To get it back if you cannot get to it now you can use SD image in 2nd post. It is very easy to fix this by doing that. |

1 block: 9.2 minutes
That's the last 504 blocks and it's about 8% faster than current difficulty. So far for the ~1400 blocks already completed we have the average at around +9% and the 504-block line is taking a dive. I'd say it's likely it will stay below 10%. Around 4 days left. I would be happy if it's under 10. We were do one day with this with having so many low percentage changes in a row. I am still hoping it's a one cycle with higher difficulty percentage and then goes back down. |
