Investing in cryptocurrencies remains a very popular and profitable activity, which allows for substantial profits, especially in periods of fluctuating exchange rates. However, to start working with digital assets, it is necessary to obtain them - either by buying them into a portfolio at one of the many cryptocurrency exchanges, or by mining them on special devices. Although the first option promises profits, it is a risky venture that requires knowledge of all the subtleties of exchange trading. Direct mining is able to pay off much more steadily and in the long run will bring a significant profit, if you know how to choose the right equipment for it.
Before you go shopping for a suitable miner, let's find out what they are. They are separate devices specialized for performing calculations, generating cryptocurrencies by the blockchain method. This way it is possible to significantly increase the speed of bitcoin mining rather than running programs on a work computer. To date, there are two types of miners:
Farms. This is a set of devices combined into a single system for mining cryptocurrency. As a rule, farms are either FPGA modules or graphic adapters, which have high power and their own cooling system. Despite a number of advantages, such as warranty on individual devices and multifunctionality, farms have lost their popularity due to the low mining performance of the most popular cryptocurrencies. Since the same bitcoin with their help is almost impossible to get, the farms are used mainly for farming bitcoins or less widespread, and therefore less expensive digital currencies;
ASIC. Abbreviation of Application Specific Integrated Circuit, these devices existed before the advent of cryptocurrency. Strictly speaking, these are microchips optimized for a specific task, which today are produced directly for mining bitcoins and other popular cryptocurrencies. Unlike farms, such a device has sufficient power and performance, so it is the main and most profitable way to farm digital assets.
Note that ASIC-mainers, unlike farms and FPGA-modules, are strictly limited in the choice of cryptocurrency. This means that if you buy a device to farm, for example, bitcoins, you cannot get altcoins and other coins with it - the chip in the base of the device is simply not designed to decrypt this type of blockchain. Therefore, choosing the right miner becomes the criterion of success in the field of cryptocurrency, because otherwise you risk to reach zero or negative profit.
How to choose the right miner.
The popularity of miners has caused the emergence of a huge number of devices on the modern market. Let's consider the key criteria on the basis of which one can understand whether it is worth buying a particular piece of equipment:
hashing. This shows how many operations a device will perform per second. Hashing is a critically important parameter for a miner because the number of operations greatly increases the chance of solving the most complex tasks, the reward for which are bitcoins. Since you can't find a specific solution the first time around, it is important to do as many calculations as possible in the hope that one of them will be suitable for decrypting the blockchain. Also note that the device must be competitive, in other words at least not slower than the rest of the equipment on the market, because when mining, it actually enters into a race with many competitors;
energy consumption. Mining is an extremely energy-consuming enterprise, and the more powerful the equipment, the higher the electricity bills will be. Many people pay attention to this characteristic in the last place, and in vain - if the ratio of bitcoins consumption and mining is wrong, the obtained cryptocurrency will not be enough to pay back the whole mining process. To understand whether the equipment pays for itself, divide the encryption rate by the power consumption of the equipment and estimate the costs based on the current bitcoin exchange rate. If the income from it is less than the costs, there is no point in starting mining with such equipment;
cost. Cheap equipment will be of little use - having low characteristics, it will compete with much more advanced and powerful miners. Therefore, to profit from BTC you will have to invest. If the device satisfies your needs in other characteristics, the price should not be an obstacle due to the payback.
To summarize, let us once again voice the main criterion for choosing a miner - the profit from mining with its help should exceed the costs of acquisition and operation. In this article, we will help you choose the actual devices that can provide BCT miners with profits in the long run.
The best bitcoin miners
There are many manufacturers and models of ASIC miners on the market today, so it is quite difficult to find the right one even roughly knowing your own needs. Below we list the ten best miners to focus on when choosing a good and balanced device.
1. antminer S17 Pro
This device is primarily suitable for professional and long-term bitcoin mining, and the characteristics and capabilities of the device meet this requirement. Its hash rate is 58 TH/s and power consumption is up to 2568W per hour, which is quite balanced for such characteristics. Most of the energy is taken by the cooling system of the miner, because it gets considerably hot during the operation, so the installation should be kept as cold as possible, especially if you want to save money. Also note that Antminer S17 Pro is equipped with three operating modes - weak, normal and turbo mode, each of which significantly increases the power and energy consumption.
The potential mining of the miner is about 0.0004 bitcoins per day and can be even higher with the organization of appropriate cooling conditions. Among the pluses we note:
relatively simple setup with a quick start;
a suitable power supply is supplied with the device;
switching between several modes to limit the power consumption.
At the heart of the miner is a second-generation chip BM1397, which develops an impressive speed of mining in comparison with previous generations and counterparts.
In general, Antminer S17 Pro will be a good option for beginners, but its full power it will unleash in the hands of a professional.
2. whatminer M32-70
Many experts call this ASIC the best value for money, and for good reason. Its manufacturer, Whatsminer, is quite a popular company that specializes in the production of professional miners with various algorithms, so you can be confident in the quality of the device. Its impressive performance - hash rate of 70 TH/s with a power consumption of 3360 watts per hour - also contributes to this.
