How to build your own ASIC miner

In case you have finally decided to enter the crypto mining industry and make some money with the help of hardware, then you might be wondering how to start and if you can do it on your own. If you have done your research, then you might know that ASIC mining is considered the most efficient and profitable way of mining when compared to the traditional mining of CPUs and GPUs. But on the other hand, ASIC miners can be quite expensive, making it unaffordable for many miners to start out their journey.

So the question here is, how to build your own ASIC miner and reduce the overall costs to kickstart your mining business? Is it even possible? Or should you go with the old-school method of mining with CPUs and GPUs that might not be more profitable but easier to do? Let’s check out all possibilities and see what scenario would work out the best for you!

What is crypto mining, and why is it necessary?

Before we dive into the details and check out if you can build your own ASIC miner and what would be the best choice for you, it is first essential to understand what mining actually 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 its hardware power in order to solve complex puzzles that indirectly validate the whole transaction. For doing so, each miner is paid a fee that you might have heard of by the name of network fee. The more transactions you validate, the more you will be able to earn. But for that, you will require heavy processing machinery that can quickly solve complex puzzles and equations and make the validation process quicker and more efficient.

If we talk about why mining is absolutely necessary for the crypto industry, then 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 fulfill the order and process the crypto transaction. When it comes to mining pools, they are just a group of miners that speed up the process of validation rather than burdening a single miner that will also consume 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 or processors of desktop computers or laptop computers in rare cases. Do remember that CPU mining is considered the least profitable type of mining due to the limited efficiency offered by the hardware. CPUs can merely compete with other mining systems, and that is why they are not preferred by professional miners and crypto enthusiasts. But if you are a beginner and just starting out your mining journey, CPUs can introduce you to pretty much everything and provide you with a path where you can grow, understand, and earn more.

GPU Mining

GPU (Graphics Processing Units) mining is probably the most popular type of mining all over the world due to the fact that GPUs are readily available, are relatively cheaper than mining-specific hardware, and they can be operated quite easily with just a simple computer. Not only that, there are countless programs available that come with a one-click mining process allowing you to start mining without programming or coding anything.

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.

Not only that, ASIC mining machines are quite expensive as they are application-specific and energy-efficient too. These machines can be quite noisy and heavy and should be maintained accordingly if you want them to serve for a longer term. 

Can you build your own ASIC miner?

The answer to this question can be a little tricky, depending on the type of user reading it. The simple answer is that it is not easy to build your own ASIC mining rig. First of all, you will have to have your hands on a lot of ASIC components that you would be assembling together to get started. Besides that, you will also have to know how to program, how to code, and how to add mining scripts in order to start the mining process. 

Lastly, 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 in case 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 multiple GPUs that can be easily bought from anywhere, a motherboard, a processor, a massive power supply, and a few other essentials to boot up the system. But the whole process would be 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, all you can do here is buy an aftermarket rig that would help you mine Bitcoin or any other cryptocurrency you want. I have listed two different popular ASIC mining machines below that are popular and can work great.

  • 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 as per your preferences and liking.

Again, make sure to consider all the scenarios, your budget, power requirements, environment suitability, and other considerations before making a decision.


Ultimately, it is not practical to create your own ASIC machine. There is a lot of trouble involved in the process, and you might not even succeed in the end. That is why 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.
