The Avalon Nano 3 comes out at a price of $19.99 - which will still take about two decades to break even. The device features a mining power of about 3.6 GH/s - a significant improvement over the Block Erupter above. The Avalon Nano 3 gets you a revenue of about $1 per year. However, as is the case with USB Miners, this is painfully slow and will take you almost a year to make a full dollar. One of the cheapest and the most easily adaptable USB Bitcoin miner, you can stick it up any computer and it will mine for bitcoins. However a good tool if you want to understand how mining functions. Not a very profitable device, but none of the USB miners are profitable, even in the long-long-long run. Using it according to modern day standards would give you a grand total of about $0.01 per month - basically you’d make your first dollar in about a 100 months (a little over 8 years) considering prices stay stable. It offers the users with a hash power of 330 MH/s. It was one of the first USB Miners to be created. The ASICMiner Block Erupter USB Sapphire Miner, popularly known as just the ‘Sapphire Miner’ has been around for a really long time. However, if you still wish to mine for Bitcoins, here’s a quick look at some of the best USB Bitcoin Miners: Sapphire Miner: As of 2017 there are no ‘new’ Bitcoin USB Miners as the technology is itself about 4 to 5 years old now. Similarly, USB Miners too are used to mine bitcoins by connecting them with your PC. When handling major mining operations, users usually tend to purchase an ASIC device which has only one dedicated purpose - to mine for Bitcoins. This is the most critical part as this is the actual, physical device that will do handle the mining operations. While we have dedicated chapters for each of them, let us refresh our memories by taking a quick glance at each of them: Best USB Miners. USB Bitcoin Miningīefore you begin to mine for Bitcoins using USB Miners, here’s what you’ll need. However if you’re serious about mining for Bitcoins, you should check out our complete list of Bitcoin Mining Hardware devices. If you want to learn Bitcoin Mining these are a good, inexpensive option for you. Today, if you make use of a USB Bitcoin miner, it would probably take you hundreds of years to reach even three decimal digits. However, as time progressed the mining difficulty increased and high-power devices started to take over. However then for a short period of time came the age of USB powered Bitcoin Miners which gave a short boost to Bitcoin Mining. When it all began, people were mining using their CPUs alone. USB Bitcoin miners were a big thing back in the early days of Bitcoin technology. However, it is a good tool to get the basic idea of how mining is done without investing much into it. 09160374 (currently 0.00053247 BTC)īased off of the current NMC exchange rate, my erupters have generated a total of 0.03101768-BTC in under 100 days.Īt the current BTC/USD exchange rate of $578.86, I've been able to generate $17.96 USD.Before we begin, however, it must be noted that Bitcoin Mining via USB is a primitive method of mining bitcoins and nobody who wishes to make a profit, or even the slightest amount of money through mining should use one. Altogether, a daily profit of about $0.15 per day USD.ĤxUSB erupters + $42.94 (USB Hub & Fan) + S&H = $106.16 In addition to the BTC, I generated about $0.03 in NMC. With the 4 erupters running 24/7, I use about $0.02/USD of electricity while generating on average $0.12-$0.16 in bitcoin per day. I chose mining because it seamlessly allows you to mine namecoin through the same port/pool.ĭon't use bitminter's flash miner if you want to mine alt coins with your gpus while going after bitcoin with the ASIC cards (it doesn't play nice if you have wallets running or cgminer working and you'll get a lot of rejects)- but by using a command line miner for sha-256, I can also run guiminer-scrypt or cgminer to hash out alt coins. I've had a constant 1.3-1.4Gh/s with these USB erupters, peaking at 2.2Gh/s (but that's an anomaly and not constant) I use bfgminer and set them up to run They're super easy to use once you get the drivers set up and understand how to mine. I purchased 4 erupters back in November 2013- just to run beside my 4x5970s and 3x7950s, it was an experiment and at the time I was pretty new to mining in general.Ĥ-erupters with 92mm cooling fan and powered-USB hub. Realizing I'm very tardy to this post, I'd like to throw out this update for those currently googling this question.
