bitfuryIn an effort to retain a small amount of the Bitcoin network’s hashrate I’ve added two new USB miners to my collection of Bitcoin ASICs. While Bitcoin mining is probably not the best investment you could make right now, it is still a fun hobby. The newest additions to my small collection are two Blue Fury USB miners with ASIC chips by manufacturer Bitfury. Here’s an overview of the Blue Furies and a guide on setting them up.

Ordering And Shipping

There are two variants of this USB ASIC available, the Blue Fury and the Red Fury. While there are some cosmetic differences between the two there is very little in the way of performance difference. These Bitcoin ASICs are only available through resellers. The ones I purchased were pre-orders from SSInc over in the Bitcointalk group buy sub forum, though SSInc also runs a web store. Some Bitfury ASIC products are also offered through Bitfury Strikes Back, though they don’t currently offer the Blue or Red Fury USB miners.


I pre ordered my Blue Furies in late September with an expected delivery date of the first week of October. Like most Bitcoin ASICs there were significant delays from the manufacturer which resulted in my miners not arriving until late late October. During that time the price of Bitcoin increased significantly, as did the network hash rate. This looks to have turned what could have been a break even investment into a bit of a loss, but such is the risk of pre ordering Bitcoin ASICs. The original price for these was 0.90 BTC, though that has dropped by quite a bit with resellers currently listing Red Furies for around 0.32 BTC.

A bit of compensation was given for the several week delay (0.05 BTC/Unit). To me this small gesture was enough to ensure that I will work with both the resellers and the manufacturers again in the future. The manufacturer gave a projected shipping date yet wasn’t able to meet it and thus compensated their customers. This is much, much more than has been done by many other Bitcoin ASIC manufacturers.


I’ve been hashing away with these two for a couple of weeks now without much problem. Setup was not as easy as some of the other ASICs that I’ve worked with. The drivers for Windows 7/8 had some issues but after some adjustments I managed to get them working. The advertised hashrate for these devices is 2.2-2.7 GH/s. However, many miners have reported wider ranges for their ASICs with actual performance as low as 1.8 GH/s. The two Blue Furies that I have running are currently hashing at 2.28 and 2.17 GH/s. I had hoped to hit the higher end of the range and was a bit disappointed with these numbers.


Setting up the Blue Furies can be a finicky, annoying, and somewhat lengthy process. In a world where most USB devices just work, Bitcoin ASICs are the exception. Most Bitcoin USB ASICs require special drivers that the user has to explicitly retrieve and install. Such is the case with the Blue Fury. Given that different operating systems and different configurations for the Blue Fury have presented their own problems, I’d ask that you check the BitcoinTalk support thread on the Blue Fury for troubleshooting information. What follows here is a guide for installing the drivers in order to get hashing on a Windows 7 computer.


While these may work in some desktop USB ports, you’re probably going to need a powered USB hub if you’re running several of miners. The Anker USB hub that I had been using to run my ASICMiner Block Erupters proved to be poorly spaced for these. The Blue Furies have a large heatsink that prevents them from being plugged into adjacent ports on this hub. I’d recommend getting a more widely spaced hub if possible.

  1. Download the drivers and BFGMiner from the following mediafire link, extract the files in the zip.
  2. Plug in your Blue Fury miners to your USB hub or USB ports.
  3. Navigate to Control Panel, then Hardware And Sound, then Devices And Printers.
  4. Right click on Bitfury BF1 USB Miner, left click Properties, left click the Hardware tab, then click Properties
  5. Left click on Change Settings, left flick the Driver tab, then the Update Driver button
  6. Select Browse My Computer for Driver Software, then click Let Me Pick From A List Of Device Drivers On My Computer, left click the Have Disk button.
  7. Select Browse and navigate to the folder we unzipped earlier (BFGMinerWin), select the file named BF1.ini.
  8. Press Install. A warning will likely appear saying that it is not signed, press ok (Note: If you get a permission denied message you may have to try another version of the drivers. Check the BitcoinTalk Blue Fury Support Thread for details).
  9. Once the drivers have successfully been installed navigate to the folder we unzipped, BFGMiner, then BFGMiner32, then locate the #MINE file and edit it with your specific pool settings.
  10. Double click on the MINE.bat file to start mining.

I was only able to successfully get these mining after tinkering with settings and configurations for awhile. At the moment I’m mining with a Butterfly Labs Jalapeno, 8 ASICMiner Block Erupters, and two Bitfury Blue Furies on my Windows 7 test machine. In order to get this to work I first had to get my instance of BFGMiner for the Blue Furies running (which also controls my Jalapeno), then open a separate instance of BFGMiner to run my ASICMiner Block Erupters. While it works for now I’ll be searching for a more elegant solution. If at all possible I’d suggest running your mining equipment on a Linux machine.


Note that you also need to use an updated/recent version of BFGMiner (or possibly CGMiner) in order to run these. They are not compatible with older versions of these Bitcoin mining programs.


Overall I’d say the Blue Furies were able to roughly meet their advertised specifications. On the one hand I’m happy to have increased my hash rate and retained a small slice of the Bitcoin network. On the other hand my experience with the Blue Fury was one of delay and muted excitement. The Blue Furies do seem to have advantages over some Bitcoin ASICs. For instance, they are more compact, less noisy and consume less power overall than say a Butterfly Labs Jalapeno.

The bottom line is that the Blue Fury is a somewhat overpriced and difficult to run USB ASIC miner that is unlikely to give you a return on your investment. For that reason, I have to suggest looking elsewhere for hashing power (unless of course the price of these drops considerably). At the moment the ASICMiner Cube looks promising with a price around 1.75 BTC for 30-38 GH/s.

    Let me hear your thoughts on the available Bitcoin ASICs, to include the Blue Fury and others. I’ll send 0.002 BTC or 2 Millibits to the first three people to provide some feedback on this post.

    Make sure to include a Bitcoin address!

  2. HeRetiK Says:

    Nice choice on the Bitfuries. From the current generation of ASIC manufacturers KnCMiner and Bitfury based miners have proven to be most reliable so far. ASICMiner has a good track record, but their devices always come with a premium – however at least it’s no preorder. Either way, I’d be careful with the expected ROI, even at 1.75 BTC for 30-38 GH. Nonetheless it’s probably still a safer bet than HashFast or Cointerra, for which things are not looking good right now. Other than that keep an eye on the WASP project. They might be onto something.


  3. CryptoJunky Says:

    Cointerra looked pretty promising but their delayed shipping date looks like it may hurt them. Then again, if the price of Bitcoin keeps increasing they, along with a lot of other ASIC companies, may be in a much better spot.

    I haven’t looked into the WASP project much yet, but now that you mention it I’ll have to. An open source 28 nm miner could be a big leap forward for Bitcoin mining.

    Sending a couple millibits your way!

  4. Thestygiansun Says:

    I like to hobby mine and it becoming an expensive hobby with the increasing rise in price of asic’s. I think it has to do with the price of BTC rising steady and how relatively simple it is to use asics.

    Currently KnC and Hashfast have the best price point for GH assuming you can get hardware quickly.

    I love the look of USB Block Erupters but not the price it is far too high. Bitfury’s are a pain and not as pleasing to the eye plus harder to set up.

    BFL has really good hardware it is a shame they could not keep there promises with delivery.

    Getting hardware on time is a major concern to the profitability. Someone needs to make a site that lists average shipping times for these companies.

    Have you tried the pencil line mod?

    I have two of these from the same group buy. A cpuble of pencil line on the right resister and I’m getting over 2.5 GH/s each.

    The fan in your pic is plenty to keep it cool as it runs cooler that the 33 erupted even with the pencil mod

    Hi CryptoJunky
    I am trying to get the Fury to run under Windows 7, but it is not working. I dont know why.
    Installed the driver as you wrote it, it is working says Windows. But, bfgminer cant find the device.
    Any idea what can help?


  8. CryptoJunky Says:


    Are you using the current version of BFGminer or an older version? Older versions may not support the Blue Fury which could be causing your trouble. If this is the case download/use the latest version of BFGMiner here. If it still isn’t working I’d try reinstalling the drivers or installing a different version of the drivers (the bitcointalk support thread has a couple of links).

  9. Julian Says:

    Finally it is working :)

    What I did:
    Uninstall the driver (and remove)
    installing driver again
    plugging in
    using the latest version under c:\ because on desktop there can be problems sometimes
    also have “run as admin” enabled for the bfgminer.exe

    thanks for the tip with the new version (maybe just this was the problem)

  10. Pete Says:

    Another note on how to get Bitfury to work
    You need to install the generic winUSB drivers from Microsoft.
    Then you need to assign the winUSB driver to the Bitfury using Zadig.
    Once you do that, then the miner will find it and you will start mining.
    Nevermind the original drivers… this is a better solution

    Thanks for posting solutions!

    That`ll be your firewall blocking the miner from contacting the pool.

    Hi CryptoJunky,
    I am having the hardst time having Bitminter recognize the BlueFury USB Miner -any suggestions?

  14. CryptoJunky Says:

    I honestly haven’t tried running Blue Furies with Bitminter. Have you been able to successfully install the drivers for them?

  15. biggestbit Says:

    Apparently yes, they seem to have installed properly, since windows7 recognized them. The led changed colors when installed, and for some reason bitminter’s beta recognized they were there but couldn’t kick-start them into mining.

  16. bluedeamon11 Says:

    hi can someone please tell me from where I can buy red or blue fury at the lowest price ?

  17. Jason Says:

    thank you for your directions.

    I have 5 Bitfuries. All are detected in Windows 7 but on 4 hash. After a while the 5th one that is also detected in BFGminer comes up as “SICK”. Is there any way I can get that one hashing or is it done? It never hashed from the beginning.

    Thanking you

  18. CryptoJunky Says:

    If it is the same Blue Fury that is SICK everytime then you might have an issue with that chip. Otherwise it could be that you’re not sending enough power to the set of 5. What USB hub are you using?


  19. Jason Says:

    I’m using a mbeat 13 port hub with external power. I have tried running the usb on its only but the same result. I have tried different usb ports on my pc. All the others work in the test except this one :( I just tried to flash the firmware via linux and it said it was successful but it still won’t hash.

  20. DRESI Says:

    Thanks for advice top of page.
    After I tried now for 2 days (!) my new Ice Fury to bring into business – installed thousends of drivers, progs. Surfed thousends of topics in 1000s of blogs. Plugged in and out.. nothing helps. While god old Block Erupter worked fine, Ice (Blue) Fury nope. Neither with Bitminter Client nor with bfgminer.

    Finally I did a “Live-Update” (start Setup.exe on a running Win7) everything works now fine!!

    Sometimes is it that easy – just heavy to find :)

  21. Gary Says:

    What different coins will BitFury mine besides Bitcoin?
    thx ; )

  22. CryptoJunky Says:

    They’ll mine any SHA-256 coin. Peercoin (PPC) is the largest after Bitcoin, but there’s also DevCoin, FreiCoin, TerraCoin, etc.

    I found out several things setting up my red furies on Win 7 Ultimate, 64 bit
    Points I learned:
    1) The drivers make the difference. If your driver shows as a Com port you have half the battle won.
    2) If you are trying to use a virtual com driver you have to know advanced addressing and I am not ready to go there.
    3) Bitminter works with red furies…..a caveat I saw over testing was the Java based program was there were more stales than from BFGminer. Wireless is even worse.
    4) BFGminer likes the red furies and once I set if my connection string to my bitminter pool all was great. I chose to use a manual start using M+ and the command bf1:all and all the devices plugged in appeared.
    5) The only real way to troubleshoot power issues as there are only so many that can run on a USB hun is to use a usb power meter about 7-8 dollars on ebay.
    6) overclocking needs lots of cooling and the current is not linear so the heat losses are basically not worth gain in mining unless at a $1000 BTC
    7) I have bought red furies from several suppliers. 1 lot of 4 would not run at all for even a day and I had to send them back…all the others would run for days.
    8) When running in a hub the output can be irratic at times…Look at the shift average for a true reading.
