The increasing popularity of bitcoin and the profitability of mining this cryptocurrency have made the bitcoin mining industry vast day by day. As you know, personal computers can no longer be used to mine bitcoins, and we need special devices called ASICs.
On the other hand, due to the competitiveness of the mining process and the difficulty of mining, new and more efficient devices are usually introduced to the market every few months. After that, they slowly remove the older devices. In this article, we will first explain a bit about the criteria for selecting a mining machine. Then we will introduce the best bitcoin mining machines in 2021.
Bitmain Antminer S19 Pro
What is the best bitcoin mining machine?
In January 2021, the Bitmain Antminer S19 Pro was recognized as one of the best bitcoin mining machines in the industry, and you can read more about it below.
Of course, which mining device is better is relative. Several devices may use in some areas and conditions. But they are not profitable in other areas and conditions.
The best mining machine is a machine that has these features:
- Long life
- Electrical consumption
- Speed of the mining hardware
- Faster return on investment
Many other factors, such as the price of bitcoin, electricity tariffs, and the difficulty of the bitcoin network, affect the return on investment, although these factors were unique to the device. The payback period is the time when the money to purchase the device and its ancillary costs are returned to the owner of the capital.
Given the above, the best and newest mining machine is not always the most popular. For example, although the Bitmain Antminer S19 Pro is the best bitcoin mining machine on the market in 2020, many large farms still use the older S9J and other models.

What are the top bitcoin mining machines in 2021?
Here are the top four bitcoin mining machines. These devices will be the most productive among miners until the first half of 2021.
To perform the mining activity, everyone must provide the device according to their activity area and conditions. It may make more sense for one person to use some older devices. Also, note that higher power does not mean that the device is better. Factors such as power consumption, longevity, weight, sound, and size play a key role in mining profitability. The following is a list of factors such as energy efficiency, power, and consumer acceptance.
- Bitmain Antminer S19 Pro,
The 19-series miners are now the top of Bitmain products. Bitmain is the largest manufacturer of mining machines. With a power of 110 terahash/s and electrical consumption of 3250 watts, the S19 Pro is higher in energy efficiency (power than electrical consumption) than its previous BitMain models and current competitors.
- MicroBT Whatsminer M30S++,
After Halving Bitcoin, which halved the rewards of mining this cryptocurrency, the Whatsminer M30S++ with 112 terahash/s and 3472 watts of power consumption was able to be in the highest category.

- Canaan Avalonminer 1246,
In January 2021, Canaan launched its new device, the AvalonMiner 1246. This device will market with a hash rate of 90 terahash per second and power consumption of 3440 watts, which will make it the most powerful device of this Company.
Bitmain Antminer T19,
The Antminer T19 has about the same dimensions and features as the S19, but at 84 terahash/s it looks weak compared to the S19 Pro. The power consumption of this device is 3,150 watts. By considering its cheaper price, it can be an economical option.
