Bitcoin mining is the process of adding verified transactions to the public ledger know as the blockchain. It is the process through which new bitcoins are released. Mining hardwares are the devices use to compute these cryptographic problems for transaction verification.
There are different types of mining hardware devices;

  • CPU : During the advent of bitcoin mining, central processing units(CPU) were the first hardware used by miners to mine bitcoins and originally the device intended to do so when bitcoins were created. As the mining process became difficult, CPU speed were no longer fast enough to solve cryptographic problems. leading to the adoption of GPU by miners.
  • GPU : Graphical processing units(GPU) as a type of hardware miner was adopted by miners and used to compute problem to find new blocks as it was in somewhat better than the CPU. Graphics card were used because they were faster and consumed less power when compared to the CPU.
  • FPGA : Not long after the advent of GPU as a hardware miner device was introduced, Field-Programmable Gate Array(FPGA) devices was introduced into the mining industry by an Industry with custom mining devices and equipment that out performed both the GPU&CPU every aspect as far as a mining hardware was concerned. These devices came in form of USB and can be connected conveniently by simply attaching them to your computer. FPGA are better than CPU and GPU because it consumed way less power and produced better results. As a result of this improved and introduced technology, concentrated mining farms sprang up.

   Application-specific integrated circuit (ASIC) is the best mining hardware device and have take over the bitcoin mining process from CPUs, GPUs & FPGA devices completely. They are created solely for the purpose of solving cryptographic problems and finding new blocks. This new generation of mining device are produced by some hardware miner companies that are well known in the mining industry.

If you still don’t know by now, I’ll like to emphasis to let you know that; “Crypto-currency is the financial future.”  So if you’re currently not engaged in bitcoin, my advice is you should as soon as possible try to get involved in bitcoin.

Due to the constant increase in popularity of bitcoin and mining, ASIC mining rigs are in high demand and the daily search on google,bing and yahoo search engines on bitcoin and how to acquire bitcoin are statistically remarkable, so is the increase in signups flooding into mining pools.


If you’re interested in purchasing a miner, there are some things you need to consider before doing so;

Hash Rate : The speed at which the miner can perform a cryptographic task should be given great consideration. How many hash per second can the miner produce, this is important because mining is very competitive and whoever finds the block first gets the reward. Since cryptographic problems are complex, you need a miner with high hash rate to increase your chance of finding the block first to acquire the reward. Hash rate is measured in megahash, gigahash and terahash per second.

Energy Consumption : Mining as a process must consume electricity. When looking for a good ASIC miner, you should purchase a miner with high conversion of electric power into output because mining really consumes a lot of electrical power so the more powerful the hardware, the more energy it is going to consume. You don’t want to end up spending more on electric bills than what you actually make from mining.

Price : Price is a very important factor to consider when if you are looking for the most efficient ASIC miner to buy. A cheap miner will definitely not be as efficient as an expensive miner in aspect of mining speed, energy consumption and even total output in productivity. If you really want to invest in mining, its better you strive for quality because the best ASIC miner does not come cheap.
