Best Bitcoin Mining Hardware 2021

If you have decided to join Bitcoin mining, your best bet will be to use specific integrated circuits(ASIC) hardware. The hardware is designed to mine Bitcoin specifically. However, selecting the best hardware can be a challenge since the market is saturated with various options. 

The situation is further complicated considering that new mining hardware hits the market almost every few months. Here, you will learn about the best Bitcoin mining hardware in 2021. However, it is vital to look at factors determining the best mining hardware. 

What is Bitcoin mining?

Bitcoin mining refers to the process of verifying bitcoin transactions and recording them in the blockchain ledger. In the blockchain, the transactions are verified by Bitcoin miners. As highlighted, initially, Bitcoin mining was done using computer CPUs. However, mining is now dominated by application-specific integrated circuits (ASICs). Learn more about Bitcoin Mining here

How to Find the Best Bitcoin Miner

Bitcoin mining has undergone massive changes over the last decade. As highlighted, mining has shifted towards ASIC hardware. Here are vital aspects guiding you in selecting the best miner. 

Bitcoin mining hardware varies in price based on factors like operational efficiency, durability, and computational power. The golden rule is that cheaper hardware will deliver lower efficiency and consequently lower profitability. Before opting for a specific price, incorporate it into your profitability analysis while considering the expected lifespan of the hardware into account.

The higher the hash rate of the hardware, the more likely it is that the miner’s hardware will solve the next block in the Bitcoin blockchain. To easily solve the next blocks you need to join a mining pool and combine your resources to increase the cumulative computing power. 

It would be best if you went for a device with a higher hash rate. However, higher hash rate hardware is typically more expensive. Always factor in the profitability of your Bitcoin mining venture. 

Another key factor to consider is electricity consumption. If you opt for hardware that costs a lot in electricity, it will likely eat into your profits. The cost of electricity majorly depends on where you live since some regions attract high charges compared to others.  However, If electricity costs are affecting your profitability, you can opt for more renewable energy sources since they don’t cost a lot. 

Here is the best Bitcoin mining hardware in 2021:

Antminer S19 Pro

Antminer S19 Pro is a brilliant product by Bitmain. The S19 Pro offers an energy efficiency of 29,5 J/TH with a maximum hash rate of 110 Th/s for the power consumption of 3,250 W. Under normal operating circumstances, the S19 Pro temperature ranges from 5℃ to 40℃. While mining, it has a noise level of 75db. 

In terms of Bitcoin mining profitability, it is not easy to tell how much the S19 will return due to fluctuating Bitcoin prices. However, using online profitability calculators can give a reasonable estimate. Based on the S19 characteristics, tt can return an annual profit of $2600 at the current mining difficulty and price.  

Bitmain Antminer T19

The Antminer T19 is another excellent miner from Bitmain that comes with the SHA-256 algorithm with a maximum hash rate of 84Th/s for a power consumption of 3150W. The Antminer T19 has custom-built chips found in the Antminer S19 and S19 Pro, ensuring efficient Bitcoin mining operations. The T19 also utilizes the APW12 power supply and upgraded firmware for faster start-up speeds to offer an optimized mining experience. Although the profitability relies on the price of Bitcoin, the T19 has returns of at least $20 per day. The miner can be purchased on the official Bitamain website. 

Whatsminer M30S++ 110T

The M30S is another powerful ASIC miner from MicroBT that can achieve a hash rate of 112T at 31J/T. The hardware was among the first Bitcoin miners to reach such power efficiency. It comes with a 3600W – 220V power supply set up on top where it eliminates the nine-pin cables and makes it easier to plug into your power outlet.

The M30S++ is set up with a fan system capable of producing peak hashing power while keeping the hardware cool while mining Bitcoin. Whatsminer factors in all users as it is easy to set up. All you need to do is plug-in power and internet, find what IP address the box was assigned, and then put that IP address in a web browser to login to the graphical interface.

The Bitcoin profitability of the M30S++ can hit $40 per day, making it one of the best mining hardware with good returns. Notably, like other MicroBT miners, the M30S++ is cheaper than the Bitmain counterparts.  

Bitmain Antminer S19J

The Antminer S19J will officially hit the market in July 2021, and it will allow Bitcoin miners to mine the asset under the SHA256 algorithm efficiently. Like other miners in the S19 series, the S19J boasts of superior performance.  Based on these features, the S19J will rank as one of the best Bitcoin mining hardware.

The Antminer S19j also comes with a hash rate of 90Th for a power consumption of 3250W. With operation temperature ranging between 5-35° C. The miner promises profitability of up to $33 per day.   

Antminer T17e

This model has been designed to return value for money. The Antminer T17e offers a hash rate of 53 TH/s and a power efficiency of 55 J/TH. Bitmain went all out to improve the T17e power efficiency and hash rate have been achieved from the company’s strength over the years.

The model has also been designed for more stable operations in the long-term to reduce maintenance costs. Bitmain focused on the dual tube heat dissipation technology which improves how efficiently heat dissipates. The models are also equipped with a more secure software system to prevent malicious attacks. 

Canaan Avalon 1246

The Avalon 1246 is a high-efficiency Bitcoin mining hardware with an impressive high hash rate for a Bitcoin miner in its category. The hash rate comes at 90 TH/s with a power consumption of 3420Watts. Additionally, it bears an innovative new design made from a strong alloy material for maximum convenience and space. This ASIC miner design saves on flexibility with the ability to be placed either horizontally or vertically during the mining. The Avalon 1246 has a plug-and-play deployment and built-in power with excellent stability.  


The highlighted ASIC miners vary in factors like efficiency, profitability, and price. These are the key features for the best mining Bitcoin experience. Generally, your mining hardware of choice solely depends on your needs. However, before going for a specific cryptocurrency miner, carry out a Bitcoin profitability analysis to ensure you recoup your investments.

You also need to assess your region’s cost of power since it is key in determining the profitability of your mining rig. Furthermore, based on your location, Bitcoin mining might be considered a business. Therefore, you need to look out for Bitcoin mining-related taxes. It is also vital to note that when Bitcoin rises in price, mining becomes more profitable.
