Which ASIC to choose in 2021?

How to choose an ASIC that will generate stable income and at the same time will not be too expensive and difficult to installoperation? Given the rise in electricity prices and the volatility of the cryptocurrency market, the issue remains relevant.

ASIC (Application Application Integrated Circuit)– is a microchip designed for a specific application – cryptocurrency mining. ASICs can be compared to conventional integrated circuits, such as a microprocessor or RAM chips in a PC. The ASIC can be prefabricated for a specific application or custom made for a specific application

ASIC for cryptocurrency mining is made specifically for calculating hashes using one of three algorithms: SHA-256 – for mining BTC, Scrypt – for Litecoin, X11 algorithm – for Dash.

Today it is not difficult to find and buy an ASIC miner. There are many different brands of ASICs on the market.

Typically, crypto enthusiasts choose their miners based on four main parameters:hashrate,power usage,priceAnddimensions.

The best ASIC miners on the market are 5 models:

1. Antminer S9

S9 – the most energy efficient ASIC miner fromall available on the market. Antminer S9 is approximately two and a half times more efficient than Antminer S7, as it uses only 0.1 Joule per Gigahash. Besides being energy efficient, it is also one of the most profitable ASIC miners.

2. Antminer R4 

Solid hashrate (8.6 TH/s ±5%) and relatively low price (about $1000) make Antminer R4 one of the best offers on the market. It is worth noting that the R4 is much quieter than other ASICs, thanks to the updated cooler. 

3. Antminer S7

Popular choice among miners – AntminerS7. The miner is not particularly expensive and quite effective. It is noteworthy that immediately after launch the S7 cost about $2000, but then its price was significantly reduced – $545 new or $500 and below on Amazon. 

Antminer s7 is equipped with 28nm BM1385 ASIC chips, which are cooled by a dual cooler. Miner users also note that it is quite easy to set up and start mining on the very first day.

4. Avalon 6

The only ASIC on our list not released by Bitmain. Canaan has already launched several miners under the Avalon brand, but Avalon 6 has gained the most popularity. 

Avalon 6 is considered a “home miner” – It is quite energy efficient and very quiet and is easy to set up even for a beginner.

5. Antminer S5

This ASIC has many advantages, but the mostbig – this is its price. Antminer S5 costs up to $500, and a used ASIC can be found for $200. (However, we do not recommend that you buy miners that someone has already used before).

S5 is great for beginner miners,who want to understand the principles of operation and then buy more expensive equipment. However, it also has its disadvantages – Quite low hashrate and noisy cooling system.

In the table below, we have collected for you the general characteristics of the best ASICs in 2021:
