This user also recommends that users choose cgminer and point to a P2Pool node. Most say that the results aren’t worth the investment.įor example, one Rev 2 GekkoScience 2-Pac user recommends using a seven-port USB hub that can support USB sticks. Unfortunately, the customers say that it’s difficult/impossible to achieve a good ROI with these units. No drivers are required, and it includes Bfgminer & Cgminer support. It’s important to note that the Antminer U2 only mines BTC and, like many other USB ASIC units, can’t mine other cryptocurrencies. However, the other review is negative (1 star) and complained about the device not being recognized on three different computers.Īccording to one customer question that was answered in November 2017, this device doesn’t work anymore due to the fact that the BTC difficulty has increased. The reviewer highlights the fact that users can learn about mining, cloud mining, and more via this USB ASIC device. As of October 3, 2018, the Antminer U2 only had two reviews on Amazon. The Antminer U2 is another great example of its diverse product lineup. The company produces all sorts of mining rigs intended for a variety of PoW consensus algorithms. Bitmain Antminer U2īitmain is the biggest player in the crypto mining market. Note that shipping costs are not included in the following costs and that prices can fluctuate. Why is this the case? Let’s find out by taking a look at the technical details and customer reviews of three of the most popular units available in 2018. Unfortunately, there aren’t as many companies offering USB ASIC miner devices. There are numerous ASIC, GPU and CPU options on the market today. Is it possible to make a net profit from a USB ASIC miner? We’ll explain more in the costs versus profitability section below. A smaller investment means that you won’t go into a large deficit. However, it’s essential to look at this from an ROI standpoint. You should expect lower profits with a USB ASIC miner. Competing against other miners who use a traditional mining rig (or several) with a simple USB ASIC miner isn’t a realistic goal. A lower hash rate drastically reduces your chances of finding the next block and receiving the mining reward. When it comes to cryptocurrency mining, hash rate is quite possibly the most important factor. Disadvantages of USB ASIC Miners Lower Hash Rates It’s even possible to mine with a laptop using a USB ASIC miner. This allows you to mine from practically wherever you can connect to the internet. With a USB ASIC miner, however, you should have the ability to utilize both desktops and laptops. In many cases, even small operations can take up a lot of space.įor people who either travel often or don’t have enough room to setup hardware mining rigs, it can be difficult to maintain a traditional mining operation. If you’re an experienced miner or even someone who is new to mining, you probably know about how expansive mining operations can be. In contrast, the process of setting up with a USB ASIC miner is pretty simple, and several tutorials are available. It takes a while to configure one and start mining cryptocurrencies. For the most part, mining rigs aren’t plug-and-play. One of the most difficult aspects of starting a successful mining operation is the setup process. However, the loss of investment would be significantly less in comparison. Yes, this would affect USB ASIC rigs as well. Because they can’t be reconfigured for other purposes, this could mean a significant loss. This means that expensive ASIC mining rigs could become obsolete out of the blue. For example, projects are changing consensus algorithms to become more ASIC-resistant. There are also a few other investment factors to consider. There are some units like the 21 Bitcoin Computer that cost $150, which can technically be classified as a USB miner, but these are on the high end. In comparison, a USB ASIC miner costs less than $50 in most cases. A high-quality ASIC rig could cost over $3,000. Advantages of USB ASIC Miners Lower CostsĮven an average-quality ASIC mining rig can cost a few hundred dollars. Why Use a USB ASIC Miner Over Mining Hardware?īefore getting started, it’s important to ask yourself, “Why should I buy a USB ASIC miner?” Depending on your purpose, the disadvantages can vastly outweigh the advantages. Finally, we try to assess whether or not the profits justify the costs of buying one of these devices. In this article, we look at some of the top USB ASIC miner devices on the market as well as explain the advantages and disadvantages of using a USB ASIC miner versus traditional mining hardware.
