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.
