USB bitcoin miner is simply a Bitcoin mining device which can be performed with the computational power of electronic devices. Many of you might not be aware of Bitcoin mining, it is the process of verifying and identifying transactions and adding them into the public ledger which is also known as Blockchain. So, it is a kind of puzzle which is solved by computers and in reward, they get bitcoins as a block reward. Bitcoin mining can be done by anyone who has access to the internet and hardware to mine bitcoins.
When Bitcoin was invented mining was performed by CPU. By the time difficulty in mining increased significantly and profits were now limited to mine with PC’s while electricity costs were more than a block reward. So, Mining efficiency was enhanced with the use of a comparatively faster device ‘Graphical Processing Unit‘.
The Field-programmable gate array can be reprogrammed to the desired application or can be given functionality after getting manufactured. This technology was more effective than GPU’s and CPU’s at performing hash calculations. Now Field-programmable gate array is now superseded by the Application Specific Integrated Circuits(ASIC). ASIC miners are now the concentrated concept of any mining farm.
Introducing USB Bitcoin Miner
As we discussed above that Bitcoin Mining can be performed by any electronic device to perform a hash function. As there was a rising popularity of mining all over the world, there was an introduction of USB powered mining devices. Companies such as Bitmain started offering USB sticks which have seamless connectivity and lower power consumption. One of the most popular USB miners is Antminer U2 by Bitmain.
When USB miners are plugged into a computer they start performing the hash functions. These miners use software such as BGFminer, MinePeon, Asteroid, Macminer. A standard computer has two to there ports for USB we can use a USB hub to connect multiple devices’s. These USB’s are usually connected to small or low cost computers such as Rasberry Pi which is suitable for mining bitcoins and overclocking USB miners. Cost of these USB’s are very low Atminer U2 will cost you for only $50 with 1.6Ghs hash rate for mining Bitcoins.
It is not a matter of money or ROI
Purchasing and using these USB sticks are fun and a very interesting way to learn about mining. You can mine some bitcoin while browsing on the internet with no extra electricity cost. Start mining and give your contribution these disrupting networks.
