Stickminers) are not profitable ways to mine Bitcoin.
To quickly get up-to-speed on what Bitcoin Mining is all about, check out our
Here’s a brief summary of the history: Originally, Bitcoin mining was only performed on desktop or laptops. Remember the rule
? But as Bitcoin grew in value, developers released a more efficient method called graphics processing unit (GPU) mining. GPU mining was followed by
in May 2013, the very first ASIC miner appeared in the form of a USB miner:
Standard Bitcoin ASIC miners are shoebox-sized pieces of equipment, which consume more electricity than most desktop computers. Since such devices cram many mining chips (which span multiple circuit boards) into a single case, they end up being big, hot, noisy, and heavy.
Although economic efficiencies favor this design, Bitcoin miners don’t have to be built this way. Each USB Bitcoin Miner is about the size of a memory stick; this is proof that one or two mining chips (which are contained in a compact device) are all you need to mine cryptocurrency.
Bitcoin USB miners can also mine 13 other SHA-256 coins, including Bitcoin Cash, and Namecoin. You can view the full list on Usb Bitcoin Miner For Sale , and Namecoin. You can view the full list on
, which will also allow you to calculate the profitability of any USB miner’s hashrate for each coin.
USB miners have the advantage of not needing a separate power supply or their own internet connection. They plug directly into any desktop or laptop computer, USB miners have the advantage of not needing a separate power supply or their own internet connection.

USB miners don’t generate much heat, so they usually don’t require cooling from an internal or external fan, or an air conditioner.
Regular mining hardware creates a loud whining sound. But since USB miners don’t have an internal fan, you can mine at home or in an office, you can mine at home or in an office Usb Bitcoin Miner For Sale
The small size of USB miners means that no racks or storage solutions are necessary.
These miners also easily transportable. So unlike ASIC units, they cost very little to ship.
USB miners are pretty cheap. You can easily find one for under $100 on eBay, whereas regular miners sell for hundreds or even thousands of dollars.
Multiple USB miners can be attached to the various ports of a computer or to a
The major drawback of USB miners is their comparatively low hashrate. Most USB miners only feature a single, outdated ASIC mining chip.
To match the hashrate of any modern standalone ASIC miner, you’d need to spend far more money on USB miners and devices, in order to run them.
Don’t expect big money—or even small money—from USB miners. This kind of profit is a thing of the past.
So USB miners are definitely not an economical choice for miners. You’re almost guaranteed to lose money running a USB miner, unless Bitcoin’s price really shoots to the moon. But even then, you’d make a lot more money by running regular mining hardware.
However, USB miners are fun, educational devices. They’re good ways to learn about the aspects of mining that involve software and hardware—or even electronics in general— without investing hundreds of dollars. USB miners can also be compelling tools for teaching others about these fields.
If you want to experiment with overclocking or underclocking ASIC miners, USB sticks are perfect. It’s better to blow up a $50 Stickminer than a full, $1000+ ASIC miner! Many experts recommend getting a USB hub for overclocking, which can supply enough power for USB miners.
A final use of USB miners is collecting them as Bitcoin memorabilia, a bit like physical Bitcoins. They can be interesting conversation pieces, especially for those with stories to tell about the early days of Bitcoin.
If you want to pick up an inexpensive USB miner for educational purposes, a second-hand Block Erupter Sapphire is
, and it’s a fair option. It hashes at 333 MH/s, and a new one sells on eBay for around $35. Second-hand ones will be about half the price.

Bitmain’s Antminer U1 USB reaches 1.6 GH/s. A new Antminer
for $33, and a second-hand one sells for around $12.50. In terms of bang for the buck, it’s a slightly better option than the ancient Sapphire.
Are you looking for something that might earn more coin? Perhaps a small amount of SHA256 altcoin? Then we definitely recommend the GekkoScience 2Pac Stickminer. Just keep in mind that it won’t earn Bitcoin.
This miner contains two Bitmain BM1384 chips, which are the same chips used in the Antminer S5. The device mines at a maximum hashrate of 15 GH/s, which makes it the most powerful USB miner available.
Since the 2Pac is close to the cost of the Sapphire or U1, it offers the best value for the money, as well as the most power efficiency. So you really can’t go wrong. But to reach maximum mining speeds, you’ll have to manually tweak the device’s frequency and power.
Although this Stickminer contains Bitmain chips, it’s produced by GekkoScience, a hobbyist electronics company. The 2Pac is the successor to the
. It currently sells on the forum for a minimum of $32, plus $10 shipping within the US. In addition, you can find it on Amazon or eBay.
In forums, you can find further information or ask
. As these USB miners still enjoy a considerable amount of community support, they’re probably the best options for learning purposes. So in all likelihood, someone will be able to offer assistance if you get stuck.
