The complexity of cryptocurrency mining is growing at an incredible pace. Over time, a regular computer has become unsuitable for mining. ASICs were developed for faster operations. Their algorithm is specifically designed for performing mathematical computations. Inside a specialized casing are boards and auxiliary microchips. Such a device is designed for round-the-clock cryptocurrency mining.

What coins can be mined using ASICs?

Initially, ASICs were designed for Bitcoin, but later new models were adapted for coins such as:

• Bitcoin Cash;
• Litecoin;
• Zcash;
• Ethereum.

An ASIC is not a universal device; a specific model is created for its designated coin. This should be taken into account when purchasing such miners.

Advantages of ASIC miners

An ASIC has several advantages over graphics cards:

• The device is ready to work; you only need to plug it into the network and perform minimal setup;
• One ASIC replaces several graphics cards; the device has high performance and provides significant income to its owner;
• ASICs are highly repairable; the secondary market always offers a wide selection of parts and power supplies for self-upgrades;
• The thermal energy can be used for heating spaces, and this method has become widely popular.

Disadvantages of ASIC miners

The devices have some drawbacks, especially affecting home miners:

• High energy consumption, heat emission, and noise levels;
• ASICs are prone to overheating — this is the most common cause of failure;
• The prices of ASICs are inflated — Bitcoin's exchange rate has contributed to the rise in ASIC prices, although they still remain profitable;
• Most used ASICs have undergone repairs — the market is saturated with unscrupulous sellers.

How to buy an ASIC and who is it suitable for?

It is better to buy an ASIC in a store; purchasing a device second-hand should only be done if you have specialized knowledge. When buying, you should evaluate the exchange rate of the desired cryptocurrency and the cost of electricity in your region. This data needs to be entered into a special calculator to estimate approximate income. It should be noted that it is better to house ASICs in a separate room with quality electrical wiring and a ventilation system. Despite some disadvantages, an ASIC remains the simplest and most profitable device for cryptocurrency mining.
