Key Takeaways

  • Crypto mining is the process of validating new crypto transactions to prevent fraudulent or scam activities on the blockchain network. It is necessary for the crypto industry as no transaction can be processed without it.
  • CPU mining is the least profitable type of mining, while GPU mining offers better returns but still less than ASIC mining.
  • ASIC mining is the most profitable but also the most expensive option, and it is not easy to build your own ASIC mining rig due to the complexity of components and programming.
  • The best course of action for beginners would be to set up an advanced mining rig consisting of multiple GPUs.

If you've decided to delve into the world of cryptocurrency mining with hopes of making a profit through your hardware, you may be wondering about the best way to get started. You have probably come across ASIC mining, during your research, which is renowned for its efficiency and profitability; it is the superior alternative to traditional CPU and GPU mining. However, the higher costs associated with ASIC miners can be a barrier to entry for many aspiring miners.

This raises the question: Is it possible to build your own ASIC miner to cut down initial expenses and kickstart your mining operations? Or is it more prudent to stick with the conventional approach of CPU and GPU mining, which may not offer the same level of profitability but could be simpler to implement? Let's evaluate all the available options and determine the best course of action for your unique situation!

What is crypto mining, and why is it necessary?

Before we dive into the details and learn if you can build your own ASIC miner, it is first essential to understand what mining is and why it is necessary.

Mining is the process of validating new crypto transactions to ensure that there are no fraudulent or scam activities on the blockchain network. Whenever a crypto transaction takes place, a miner provides their hardware power in order to solve complex puzzles that indirectly validate the whole transaction. In return for doing so, a miner is paid a fee, also known as a network fee. The more transactions you validate, the more you will earn. But to do that, you will require heavy processing machinery that can quickly solve complex puzzles and equations, to make the validation process quicker and more efficient.

If you wonder why mining is necessary for the crypto industry, it is simply because no crypto transaction can be processed without it. There must be a miner or a mining pool available to validate the transaction in order to fulfil the order and process the crypto transaction. When it comes to mining pools, they are a group of miners that speed up the process of validation rather than relying on a single miner, which will take more time.

How can you mine BTC and other cryptocurrencies?

Here are the ways through which BTC and other cryptocurrencies can be mined. The ASIC mining process is also discussed briefly below. 

CPU Mining

CPU stands for Central Processing Unit for any computer, and in this context, we are talking about the CPUs of desktop computers. Keep in mind that CPU mining is the least profitable type of mining due to the limited efficiency offered by the hardware.

CPUs cannot compete with other mining systems, so are not preferred by professional miners and crypto enthusiasts. However, if you are a beginner and just starting out your mining journey, CPUs can introduce you to the process and provide you with an opportunity to learn, grow, and understand more.

GPU Mining

GPU (Graphics Processing Units) mining is the most popular type of mining around the world due to the fact that GPUs are readily available, cheaper than mining-specific hardware, and can be operated easily with a basic computer. Not only that, but there are countless programs available that come with a one-click mining process allowing you to begin without any programming or coding.

You simply click a button to start mining and click a button to stop the whole process. GPU mining offers better returns than CPU mining, but they are still less than what an ASIC miner would provide. But considering the value of GPUs, as compared to ASIC miners, you can definitely explore this option and see how things turn out for you.

Lastly, to earn even more and increase the efficiency of their GPU mining, many traders pair up more than one GPU and combine their power to increase the hash rate and earn more. For that, you might have to set up a separate stand on which you could place the GPUs and then run all of them at once to start generating a higher hash rate. It is only recommended if you have a colder environment to set up the mining rig along with stable electricity flow.

ASIC Mining

The last choice that remains for you when it comes to mining is ASIC (application-specific integrated circuit) machines. ASIC machines are definitely the most profitable and efficient compared to the others. The only issue is that ASIC machines are designed explicitly for a particular crypto asset rather than supporting a variety of cryptocurrencies to be mined. When purchasing or building your own ASIC machine, you will have to keep this aspect in mind and determine which cryptocurrency you want to mine.

ASIC mining machines are quite expensive as they are application-specific and energy-efficient too. They can be very noisy and heavy and need to be maintained accordingly if you want them to last for a long time. 

Can you build your own ASIC miner?

The answer to this question can be a little tricky, depending on the type of user you are. The short answer is that it is not easy to build your own ASIC mining rig. First of all, you will have to gather a lot of ASIC components that you will be assembling. Besides that, you will have to know how to program, how to code, and how to add mining scripts in order to begin the mining process. 

Finally, the components of the ASIC mining rig are not readily available as there are almost no brands or companies that sell the parts of the ASIC mining rig separately. So the best course of option for you if you want to develop your own mining rig would be to set up an advanced mining rig consisting of multiple GPUs. For that, you will only require several GPUs that can be easily purchased, a motherboard, a processor, a massive power supply, and a few other essentials to boot up the system. This process is much easier than building your own ASIC miner.

Best ASIC mining machines to buy

As it is practically impossible for you to make your own ASIC mining machine, the best option is to buy an aftermarket rig that you can use to mine Bitcoin or any other cryptocurrency you like. I have listed two different popular ASIC mining machines that are popular work well from my experience.

  • Bitmain Antminer S19 Pro: Antminer S19 Pro is the successor of previous releases of ASIC machines from the same brand, and it is more powerful, efficient, and lightweight. This machine can mine BTC, BCH, and BSV with great immersive power and can give you immense profits. 
  • WhatsMiner M Series: WhatsMiner also produces some great ASIC mining machines that you can check out. There are various models available that you can buy according to your preferences.

Make sure to consider your personal needs, your budget, power requirements, environment suitability, and other factors before making a decision on which ASIC miner to purchase.


Ultimately, it is not practical to build your own ASIC machine. There is a lot of trouble involved in the process, and you may not even succeed in the end. In my experience it is better to buy an ASIC machine and set it up yourself, or use GPU mining rigs instead. provides all its content for informational purposes only, and this should not be taken as financial advice to buy, trade or sell cryptocurrency or use any specific exchange.
