The use of specially designed equipment for mining digital currencies is relatively recent. The reason was the explosive growth in the cost of the “crypto”, and then there was a need for the best miners to achieve the most effective result.
How an ASIC miner works application-specific integrated circuit, “special purpose integrated circuit”) is not too different from any other hardware (video card or processor). The main difference is only in efficiency. For example, to achieve the same performance as that of a miner, it is necessary to build a “farm” of a dozen video cards that will consume an incredible amount of electricity.
Initially, ASIC systems were used exclusively for bitcoin mining. However, soon the technology began to be used to earn altcoins, where competition is much lower. This method also has its drawbacks. So, ASIC miners can work on one or two algorithms. Therefore, if there are significant changes in the cryptocurrency market, then the devices are useless. It is not possible to reshape them.
It is quite easy to start mining with ASICs. It is enough to connect the equipment to a power outlet and to the Internet, and then install the software. Separately, we note that there must be at least 150 GB of free space for storing data on a PC. Healthy Food Near Me has compiled a rating of the most relevant devices for 2021.

How to choose a cryptocurrency miner. Expert advice
To choose the most suitable model, you need to take into account a number of features, both financial and technical. To deal with this issue, ” Healthy Food Near Me” helped IT company system administrator Dmitry Rakivnenko.
Hesreit
As in the case of processors, this indicator plays the most important role when choosing. After all, the hash rate determines how many “coins” will be mined and for how long. If you subtract the cost of energy consumption, then you can name the most accurate payback period. The hashing range is from 3,65 to 115 TH/s. According to the expert, 12-16 TH / s will be the most optimal for working at home.
Microprocessor
Another important factor that affects the quality of work is the frequency of the microprocessor. It is she who sets the performance and the number of operations that the ASIC is capable of performing per second. The higher the frequency, the better. The average ranges are 600-650 MHz.
Energy consumption
As mentioned earlier, the payback period depends on this parameter. The high power of the ASIC miner requires a large amount of electricity. Be sure to consider this before purchasing. The range of energy consumption ranges from 1 to 100 W/h.
Охлаждение
This factor significantly affects the service life of the equipment. The presence of two fans is considered optimal. However, remember that a large number of fans creates a very high noise level.
Warranty period
As a rule, the equipment operates 24/7. During mining, coolers and other components fail, so the warranty from the supplier will be an important factor. For this type of equipment, the average warranty period is six months.
