What is Bitcoin USB miner?
Bitcoin USB miner is a device that connects through the USB port of a computer and mines BTC. Bitcoin USB miners work similarly to Full Programmable Gate Array (FPGA) or Application Specific Integrated Circuits miners (ASIC).
How does a Bitcoin USB miner work?
The USB has compatible chips which are plugged into the USB ports of a computer. The devices only process Bitcoin mining operations.
Bitcoin USB miner devices are widely available, but one has to select the proper device seeing as these devices cannot generate a significant amount of profit.
The USB hub must be of good quality and be well powered so that you may run some USB devices alongside on the USB ports in order to increase your chance of profitability. However, these USB devices will generate a lot of heat as they run continuously. This will incur the need to install USB fans in order to bring down the temperature.
Advantages of USB ASIC Miners
– Lower Prices
When compared to an ASIC mining rig, USB miners are much cheaper. An ASIC of average quality can cost a few hundred dollars and a high-quality rig could be worth even $3,000, while a USB ASIC miner is usually around $50. There are some units that cost $150, but these are on the pricier side of the spectrum.
– Easier Setup Process
ASIC rigs usually require a complex setup process. Generally, you can’t just plugin mining rigs and start mining right away. You will have to configure the hardware before you can start mining. On the other hand, USB miners are quite easy to set up, and there are plenty of easy-to-follow tutorials available online.
– Less Space
Mining operations can take up significant space. In many cases, even small rigs can become expansive space-wise. If you do not have sufficient room to host such operations, then a USB miner would be more convenient for you from this perspective.
For those of you that travel often, it can be problematic to keep up a traditional mining operation. However, with a USB ASIC miner, you are able to use both desktops and laptops, allowing you to mine from practically wherever have internet connectivity.
Disadvantages of USB ASIC Miners
– Lower Hash Rates
In cryptocurrency mining, the hash rate is one of the most important factors that influence your profits. A lower hash rate significantly decreases your odds of discovering the next block and receiving the mining reward. Competing with traditional mining rigs with a simple USB miner isn’t a realistic goal.
– Lower ROI
A USB ASIC miner will not generate substantial income. From an ROI point of view, a smaller investment means that you won’t have a big dent in your budget that you have to cover as soon as possible.
Examples of USB ASIC Miner Devices
21 Bitcoin Computer
The 21 Bitcoin Computer can barely be considered a USB Bitcoin miner. It was mostly developed to create apps, services, and devices that can be used with Bitcoin. It has a low rate of profitability to hash ratio, so it is not recommended by many BTC miners.
ASICMiner Block Erupter USB 330MH/s Sapphire Miner
The Sapphire Block Erupters were among the first USB Bitcoin miners to appear on the market. It can be used by those that want to learn about mining, however, with its hash power of 330 MH/s, it will not generate any substantial profit.
Avalon Nano 3
The Nano 3 is easy to use, as you plug it into the USB port on your computer and it doesn’t require any additional fans. Of course, the hash power is right around 3.6 GS/s, which equates to a maximum profit of $1 per year.
Bitmain Antrouter R1 Wifi Solo Bitcoin Miner
The Antrouter has a hash rate of just 5.5 GH/s, which also puts it into the $1 per year profit category. That advantage to it is that it doesn’t cost much and it can double as a wireless router.
GekkoScience Compac USB Stick Bitcoin Miner
Compared to the other USB Bitcoin miners for novice users, this may be the best option when it comes to turning a profit by using hashing power. It can generate a profit of almost 15 cents per month, which translates to almost $2 per year.
Are USB ASIC Miner Devices Profitable?
The result of any investment depends mainly on the initial contribution and the given management. Regarding Bitcoin mining, whether by USB devices or by prior methods, its profitability will depend on the following factors:
- The initial investment
- The level of technology and ongoing advances to be developed during the mining process
- The volatility and prices of Bitcoin
But even if you use the latest technology of ASICs USB mining of Bitcoin, there will be some challenges that Bitcoin miners will encounter:
All types of ASIC devices are expected to have higher prices. This is because they will keep improving the mining difficulty and will constantly update it, which will further drive up the prices.
Cost of power
In order for ASIC hardware to efficiently compute the algorithms, they require a significant amount of electricity which cannot be sustained by the small Bitcoin mining operations. In use, the cost of power will dwarf the rewards generated through Bitcoin mining.
Unfortunately, a lot of research, history, and customer reviews show that it is almost impossible to make any good profits through mining with USB. If you are focused solely on profitability, the harsh truth is that the results aren’t worth the investment.
If you are new to mining and just want to get a little experience before entering the game, a cheap USB miner is ideal. But if you are serious about making profits, then we would suggest that you opt for a traditional hardware mining rig.
