    Regardless of your direct experience in the crypto world, most of us have at least considered trading and investing in Bitcoin. What still remains new and rather unexplored though, is Bitcoin mining and what needs to be done to get started with it. 

    Bitcoin mining can be a hobby or a profession. But in order to get started, one must have a full understanding of the requirements and criteria of Bitcoin mining. 

    In this article, we'll learn all about Bitcoin mining and most importantly, what is the best Bitcoin mining hardware of 2021.

    What Is Bitcoin Mining?

    Bitcoin mining is the process of verifying transactions by solving complex mathematical puzzles. The process is crucial for the addition of new coins and maintenance of the entire public ledger of Bitcoin, known as the blockchain. It is also used to control the problem of double-spending. Bitcoin miners receive rewards for discovering solutions to complex hash problems.

    Even though mining is a complicated process, it is greatly profitable. All you need is the right set of software and hardware settings to get started.

    How To Choose The Best Bitcoin Mining Hardware?

    Since its inception in 2009, there has been a drastic evolution in the way Bitcoin is mined. Initially, moderately powered CPUs could be used to mine Bitcoin from the comfort of your home. But as the Bitcoin network expanded, the process became more complicated, and miners had to move to powerful GPUs to keep up with the increasing demand. GPU had a drawback though—there was a constant need for a cooling system to prevent the device from being damaged from overheating.

    At present, an application-specific integrated circuit (ASIC) was created to compensate for the demand for high hashing power. The ASIC provides a high hash rate, which allows miners to mine faster and use much less electricity.

    ASIC hardware is now a go-to for every miner and here's what you should look for when setting up your ASIC for Bitcoin mining:

    Energy Efficiency

    The power required to generate a single bitcoin (BTC) is known as efficiency. The more efficient the bitcoin mining hardware is the less electricity it'll consume.

    Efficiency= Energy consumption/ Hash rate

    The higher the efficiency, the lower the power consumption of the hardware.

    Hash Rate

    The rate at which Bitcoin mining hardware can solve a complex mathematical puzzle is known as the hash rate. For instance, a PC can make close to a million guesses per second, and on the other hand, ASICs can make up to 1*10^12 guesses per second.

    The hardware that has a higher hash rate, means the miners can solve the next block in the blockchain faster. As a result, this type of hardware is more expensive than hardware with a lower hash rate.

    Price

    The price of Bitcoin mining machines depends on their efficiency, power consumption, and longevity. Cheap hardware will deliver less Bitcoin because of low efficiency and low profitability. So, the faster the mining machine, the higher the price tag it'll have.

    All three factors are responsible for determining the profitability of ASIC mining hardware, so it is recommended to buy mining hardware by checking its hash rate, power consumption as well as price.
