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.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.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.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.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.Table of ContentsBitcoin USB Miners ComparisonASICMiner Block Erupter USB 330MH/s Sapphire MinerGekkoScience Compac USB Stick Bitcoin MinerAvalon Nano 3Bitmain Antrouter R1 Wifi Solo Bitcoin Miner21 Bitcoin ComputerMore Bitcoin Mining Hardware ASICs (None-USB) The plus side is it works as a wireless router, so you can do some mining while providing internet for all your devices.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.

With that in mind, then, I decided to plug in a HexFury 11 gigahash/second USB miner, one of the last powerful USB miners that can actually make you a few dollars a month.First, let’s understand what this thing is.The HexFury is a USB mining rig with six small ASICs made by a company called Bitfury.The ASICs, in this case, are chips that do one thing – mine bitcoin – and they do it very well.bitcoin asic miner litecoinUp until the HexFury, most USB miners of this type could run at 2 GH/s per second or slower, enough to mine a few dollars a year.bitcoin qt speedAt this point these older ASICs cost about $12 while this model costs $200.bitcoin mt4 platformCould you mine with the smaller ASICs?Sure, but you’d essentially be burning money in a tiny bonfire.I ran a collection of three 1 GH/s ASICs and got about $1 a month.

A unit arrived from Asicrunner and I unwrapped the single chip and checked it out.On one side are the six ASICs and on the other side is a large, passive heatsink.It looks like an overgrown thumb drive with exposed innards, which should give owners of inquisitive cats pause.The device requires a 5V USB hub (Belkin makes a few good ones) and a separate fan.I used this Arctic USB fan.To mine I used a Raspberry Pi with a USB card onto which I installed Minepeon, a free mining platform that supports multiple types of ASIC miners.It is one of the simplest ways to turn your Raspberry Pi into a real mining rig and is very cool.You can learn how to install it onto an SD card here.To run the chip with Raspberry Pi Minepeon installation I had to install and recompile cgminer 4.3.2, the latest version of a standalone mining app that runs on most platforms.I had to recompile it to work with the current version of Minepeon.Once you’ve put Minepeon on an SD card and booted up your Raspberry Pi, you need to download and compile cgminer for your environment.

Here are the commands I used: ssh -l minepeon (password:peon) cd /apps/cgminer/4.3/cgminer-4.3.2.tar.bz2 tar xvf cgminer-4.3.2.tar.bz2 cd /home/minepeon/cgminer-4.3.2 ./configure --enable-icarus --enable-bitfury sudo make sudo make install cd /opt/minepeon/bin mv cgminer cgminer.hold ln -s /home/minepeon/cgminer-4.3.2/cgminer cgminer reboot This should get you the latest version of cgminer.How does it perform?Well, with the fan pointed directly at it and the hub powered on, I consistently saw 12GH/s.This enough to make about $150 a year at this current difficulty and bitcoin price.This is a screen from Minepeon.You’ll notice that at that speed we would see about 0.018 BTC per month, or about $10.Given the cost of electricity and the constant rise in the bitcoin mining difficulty rate, this will eventually fall until 11 GH/s is a paltry speed.Home mining, at this point, is more about the experience of mining than any real money making.
