The HexFury is a new USB miner on the Bitcoin mining scene that throws out the window the 5 gh/s barrier that seemed to be the limit with USB powered miners.
It uses 6 BitFury chips and the OneString board design to achieve a high output while drawing the small amount of power available to it through a typical USB powered hub.
Rafal from ASIC Runner sent me a sample of one the first production units.
I have to say I am impressed. It is still tiny. Nearly as small as my BiFury 5 gh/s unit and very cleanly built.
I plugged it in and the driver set it up automatically. Then firing up MultiMiner it was detected in a snap.
I started mining, and it immediately popped up to 9.2 gh/s with no tweaking. (There is a display bug with the current BFG/MM driver that is being worked on. The HexFury’s hash rate shows properly on the “effective” output column and the pool dashboard but does not display correctly in MM’s “Current” hash rate monitor.)
Once the HexFury miner had operated for 20 minutes it worked it’s way up to 10.73 gh/s and has stayed there for days now. I am also able to push it to 12 gh/s on my USB Hub without extra power by changing the oscillator bits to 54. The HW rate stayed well under 3%. With a USB hub that can provide more power at the port level or USB power injector you should easily be able to push it to 15 gh/s and above easily. It did all this without breaking a sweat. It stayed between 45c and 48c the whole time even with six chips. Это интересно:
Raspberry pi and GekkoScience Compac USB Stick Bitcoin .
This USB stick Miner for SHA256d based Crypotcoins like Bitcoin, Namecoin, DEM and others delivers an average hash rate of 8 GH/s and can be safely boosted up to 16 GH/s when clock rate and voltage will be adjusted. Some hardcore overclockers already achieved ~ 23 GH/s (see details here – reproduction of this setup is not recommended)
This Miner is equipped with one highly power efficient AntMiner BM1384 ASIC (same chip as on Bitmain’s AntMiner S5).
It enumerates in CGMiner software as an AntMiner U3 which gives command-line frequency control to adjust the hash rate. Moreover the miner is equipped with a fully adjustable voltage regulator that allows a core voltage range of 550mV to 800mV without requiring “pencil modding” or soldering skills.
The average power consumption is 0.3W/GH which makes this device currently (as of August 2015) the most power efficient publicly available Bitcoin mining device on the market.
The Miner will be delivered with a high performance heat sink mounted which provides a very low thermal resistance from 17.8 °C/W (natural convection) up to 3.5 °C/W (at an airflow velocity of 4 m/s). When overclocked and/or voltage regulated we highly recommend active cooling.
The power consumption depends on the clock rate and the set core voltage and varies from 2 W to more than 6 W. Usage of an active USB hub is highly recommended to avoid damage on standard USB ports.
This Miner is manufactured and assembled in EU under license of GekkoScience.com.
- 1 GekkoScience Compac USB stick miner (bitshopper manufactured) in PP gift box
- Hash rate up to 16 GH/s (when overclocked and voltage regulated). Active cooling is highly recommended.
- Power consumption: up to 6 W per USB port. An active USB hub is highly recommended.
Software and hardware requirements:
- Host-PC with Windows x86 (32-bit or 64bit), Linux (x86 or ARM) or Mac OSX.
- The Miner uses a CP2102 USB to UART bridge controller. Drivers can be downloaded here: Silicon Labs CP2102
- Please note: An active USB hub with adequate power supply is highly recommended (such as Anker 9-Port, Asicminer 49-Port, Orico 10-Port).
- Please note: Due to the large heat sink the overall height of the device is 15mm. This may cause difficulties using all USB ports of an active USB hub.

USB Bitcoin miners are available to buy, but they don’t really generate any significant profits.
They’re a good choice if you just want to fool around with Bitcoin mining and miners like the Antminer S9, S7, S5, Antminer R4, SP20, and Avalon6 are too expensive for you.
You should buy one to learn how mining works, but other than that don’t expect much! If you are serious about making profit then check out better Bitcoin mining hardware.
You can always check the profitability of a USB miner using our mining calculator.
Don’t Get Confused
There is USB Bitcoin mining hardware, which mines bitcoins.
There are also Bitcoin hardware wallets like the Ledger Nano S, which store bitcoins.
Both are USB type devices that have completely separate functions!
Bitcoin USB Miners Comparison
ASICMiner Block Erupter USB 330MH/s Sapphire Miner
The Sapphire Block Erupters were the first Bitcoin USB miners. They have 330 MH/s of hash power which would net you less than $0.01 per month.
It may be a good choice just to see how mining works, but like with most USB miners: do not expect to turn a profit.
GekkoScience Compac USB Stick Bitcoin Miner
The GekkoScience miners is just slightly better than the original block erupters.
It will net you about $0.15 per month, which is more than a dollar per year! The company claims that the device runs completely silent. It works with just one USB port.
Avalon Nano 3
The Avalon Nano 3 is a 3.6 GH/s miner, which will earn you about $1 per year. No fan is required and it just plugs into your USB port on any computer.
Bitmain Antrouter R1 Wifi Solo Bitcoin Miner
The Bitmain AntRouter isn’t exactly a USB miner, but it is similar. It’s low cost, but with that you get a low GH/s at just 5.5 GH/s which is a little over $1 per year.
The plus side is it works as a wireless router, so you can do some mining while providing internet for all your devices.
21 Bitcoin Computer
The 21 Bitcoin Computer isn’t the typical USB Bitcoin miner. It does, however, plugin to your computer via USB. In terms of $ / hash rate, it’s not a very good choice.
But since it’s still technically a USB miner we have included it in this list.
If you’re not impressed, we don’t blame you! USB Bitcoin mining was only profitable when Bitcoin was in its early years. If you just want bitcoins then invest in serious mining hardware or just buy bitcoins.
