USB Bitcoin miners are available to buy, but they don’t really generate any significant profits.
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.
There is USB Bitcoin mining hardware, which mines bitcoins.
Both are USB type devices that have completely separate functions!
|Sapphire Miner||330 MH/s||$29.99||Buy|
|Avalon Nano 3||3.6 GH/s||$19.99||Buy|
|Bitmain Antrouter||5.5 GH/s||$59.99||Buy|
|21 Computer||90 GH/s||$399||Buy|
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.
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.
