Best ASIC Miners In 2018 – Top 5

Why an ASIC Miner?

CPU’s were first used to mine Bitcoins until it was discovered by developers that GPU was far more effective and profitable. The introduction of GPU saw more miners buying it. The price of these GPU’s skyrocketed overnight because more miners were buying all GPU’s they could get their hands on. This led to the development of Applications Specified Integrated Circuit (ASIC). Since then ASIC has become the only technology used to mine Bitcoins. ASIC miners have been used because they mine Bitcoins as fast as possible and they use less power. ASIC was created primarily to solve the problem of Bitcoins blockchain. These ASIC Miners are chosen because they are quicker and use less electricity compared to order miners like CPU, GPU and FPGA.


ASIC Miner Criteria

In this article, we will discuss the best ASIC Miners you can choose. We have picked out the best ASIC based on certain necessary criteria;

  • Hashrate: this is the computing unit of the processing power of the Bitcoin network. In this article, we will make a comprehensive list of miners with the highest number of hashes generated per minute.
  • Efficiency: this is important because mining requires a large amount of electricity. It is important to select a miner that converts lots of energy into Bitcoins.
  • The price: this is important because a cheap ASIC miner would hash fewer coins.

Impact of ASIC miners on the decentralized system

The use of ASIC miners has a great impact on the decentralized system of cryptocurrencies. Instead of all Bitcoin users to verify blocks on their own, mining is shifted to occur in one particular place. To explain better, expensive miners are the most efficient and not everyone can afford to purchase them. This reason is why most of the mining of Bitcoins is done in China, there are rich investors and also, the electricity is cheap. These investors buy hundreds if not thousands of miners and mine them together in a large house. The hashrate of these miners combined with electricity will mean large profit for these investors.

However, the best way to make a profit as an individual miner is to join a mining pool. Mining pools are a network of people who work together to solve common problems. As an individual all you need is to verify a block with your hash, if the block is verified, the reward would be evenly distributed based on each individual’s contribution. This is a more efficient way for individuals to make a profit because this mining pool increases their odd of solving Bitcoins complicated algorithm.

There are different mining pools you can choose from. Some of them include:

  • Bitfury
  • BTC China
  • Antpool.
