Is Crypto Mining a Profitable Venture?

Prospective crypto miners need to understand that mining for cryptocurrency is a bit of a gamble, much like how it was for the prospectors rushing out to California with pickaxes back in 1849. Not only that, but it’s also a seriously competitive venture, with thousands of individual miners and mining companies racing to find the digital gold before everyone else. And that’s not even mentioning the money you’ll have to directly invest in the process to build or buy a specialized crypto mining rig for those who genuinely take the practice seriously.

For those willing to take on those investments, gambles, and intense competition head-on, then crypto mining may be a very profitable venture when all is said and done and they’ve gotten everything up and rolling. However, it’s important to note one thing that many people may not have considered when entering the crypto mining world; there are more ways to make money than just mining for that digital gold.

For those who don’t want to deal with the gamble and competition of traditional crypto mining, you can make a pretty significant sum of money by providing crypto miners with their desperately needed, modern-day shovels and pickaxes; crypto mining rigs. Those with a talent for building machines and with a strong understanding of computers and technology have begun fabricating their own specialty crypto mining rigs and selling or renting them to miners on the market. While it may not produce as much money as crypto mining for those who can succeed at the practice, it removes a massive amount of risk and competition, providing you with a safer and more stable way to produce some income from the crypto mining world.

What to Know About Cryptocurrencies 

Cryptocurrencies like Bitcoin have catapulted to popularity in recent years. Unlike traditional currencies, which are controlled by banks and governments, crypto is uniquely digital and decentralized. There are thousands of cryptocurrencies providing alternatives to Bitcoin, collectively called altcoins, although Bitcoin is the most widely known and accepted. Others like Etherum and Ripple are giving Bitcoin a run for its money–literally. Cryptocurrencies are built on blockchain technology, providing a framework that is nearly impossible to manipulate.

Mining Pools 

Crypto mining is a risky venture. One way that miners effectively increase their chances is by joining mining pools. These pools allow a group of miners to combine their resources, distributing earning among all members. Mining pools got their start as an integration of common mining applications. But due to their popularity, many crypto enthusiasts are creating independent pools online, which are perfect for miners building their own rigs. Every mining pool offers something different in terms of reliability and profitability. Ultimately joining the right pool takes some research.

What Will You Need to Effectively Crypto Mine?

Whether you intend to work in the outskirts of the crypto mining world by building and selling epic crypto mining machines to dedicated crypto miners, or you intend to make one for yourself for your own crypto mining operations, there are a few fundamental factors that you’ll need to understand to be successful.

What is a Crypto Wallet?

A crypto wallet is a program, service, or device that stores private and public keys for cryptocurrency transactions, ensuring that people’s crypto is safe and easily accessible. These wallets also allow people to send, spend, and receive various cryptocurrencies, such as Ethereum and Bitcoin. They come in a vast array of mediums that range from straightforward and physical to digitally complex and secure, including cold and hot wallets.

Cold wallets refer to physical storage devices, such as paper wallets and hardware wallets, while hot wallets involve online or digital wallets. The wallets themselves don’t hold your bitcoin like ordinary wallets hold money (your crypto lives on the blockchain, after all). It basically acts as proof of your ownership of your digital money. However, that’s also why it’s essential to keep your wallet safe, no matter what type you’re using. If you lose your wallet, you’ll lose access to all of your cryptocurrency.

While this information is primarily relevant for those who intend to undergo crypto mining themselves, crypto mining rig builders should still understand the basics of crypto wallets due to how essential they are within the industry. This is especially since rig builders may be earning crypto through other methods and will need a place to store them safely and effectively, just like crypto miners.

What is a Crypto Rig?

In short, a crypto mining rig is a barebones computer setup that utilizes multiple, powerful GPUs to handle the calculations that come with crypto mining. These systems require a massive amount of high-wattage power to run effectively because the GPUs are run 24 hours per day. A rig with three GPUs can easily consume as much as 1,000 watts of power when operating, which is equivalent to running a mid-sized window AC unit. You can think of a rig as a cheap PC connected to several high-performance GPUs, rather than just a single one that would be used for a standard computer.

What Will You Need to Pull Together the Ultimate Crypto Rig?

Whether you’re constructing a rig for your own crypto mining purposes or selling it to other crypto miners on the market, the first thing you need to understand is that there are three basic categories for these mining rigs; GPU, CPU, and ASIC. It’s essential to understand the distinctions between these systems, especially regarding their power and capabilities to mine for different types of cryptocurrency. For example, once, you could easily mine for Bitcoin using only the primary CPU in your desktop computer, but now very few cryptocurrencies can be mined that way. These days, mining for most crypto requires much more processing power and an impressively constructed rig built specifically for that purpose.

Your crypto mining rig will essentially look like any other desktop computer, but the components will vary significantly. The main components that ‘look’ like a computer include a motherboard, case, frame, and power supply. In most cases, any average motherboard will do. The only purpose it is serving is connecting your choice components. 

You will need sufficient storage for your cryptocurrency wallet. The most common wallets like Ether require a minimum of 25 GB, and Bitcoin requires a minimum of 50 GB. So, plan for a hard disk drive (HDD) or solid-state drive (SSD) with 100 GB to 250 GB. This will accommodate current storage needs with plenty of room for growth as you expand. 

You will also need several GPU cards. For most setups, graphics cards are the essential component that makes the rig adaptable to crypto mining. While an everyday computer only has one graphics card, a crypto rig can have a dozen. And with a system running so many GPUs, you’ll need an adequate power supply and cooling mechanisms. As a general rule, plan for one power supply for every four GPUs that you play to install. And the entire setup should be laid out with respect to promoting the circulation of airflow with several cooling fans.


GPU Crypto mining is one of the more complex methods people can use, but it is also the most common. CPU mining will be explained further in the section below, but for now, understand that it can be challenging to get a bunch of CPUs to work together effectively. It’s much easier to connect several powerful GPUs to a single motherboard and set them to accomplish a specific task. That being said, selecting suitable GPUs for the job is a tricky process, and there is no truly correct answer for which ones you should use. AMD and Nvidia, for example, are two of the most commonly used GPUs, mainly due to the range of operating options they provide for both experienced hash crackers and newer, more basic crypto miners. One great option for this component is the MSI GeForce RTX 3090.

However, keep in mind that selecting the GPU option for your crypto mining rig also means you will need to invest in a few more components for the setup to ensure everything works properly. These components include:


GPUs (graphics processing units) need to connect to something, and since a single GPU isn’t enough to effectively run a crypto mining rig, you’ll need to rely on a motherboard that can accommodate a lot of them (usually at least six). One great option for this is the MSI PRO Z390-A, which can handle those six GPUs for a very reasonable price. However, those who are looking to build a more powerful mining rig would do better by investing in the ASUS B250 Mining Expert, which can connect to up to nineteen different GPUs at a single time.

Case and Frame

All of those GPUs will not fit inside an ordinary PC case, and you can’t leave them lying around without the risk of breaking them or creating a potential fire hazard. You’re going to need an appropriately sized frame or case for your mining rig. There is a wide range of schematics available online so that you can construct your own, but there are several pre-built, low-cost options that you are welcome to invest in as well, like the 8 GPU 4 Fans Steel Coin Open Air Mining Frame Rig Case. However, keep in mind that whatever frame you select needs to have as many slots as you have GPUs in your rig, and you should always ensure that it will correctly fit in its intended place in your home.


It’s essential to select the best possible power supply unit (PSU) for your homemade crypto mining rig. This is to ensure the rig itself can have enough power to run effectively and because the system’s overall power consumption is a significant factor in how profitable your rig will be. A PSU should provide enough power to satisfy the various power-hungry components within the machine but not give so much power that a significant amount will be wasted. Some top-quality PSUs to consider for your homemade rig include the Thermaltake Toughpower 1500W and the EVGA SuperNOVA 1600 T2. Generally speaking, you should try to invest in a PSU with at least an 80 Plus Gold certification.


Central processing unit (CPU) crypto mining is relatively basic in how its operations compare to GPU and ASIC mining (which will be explored below). It involves using the natural processing power of your computer’s CPU to generate hashes, though that does mean this method is much weaker than the others discussed on this list. This mining method is only effective for mining specific types of crypto, such as Monero- which has been specifically designed to be “ASIC resistant” and as decentralized as possible. 

CPU mining does have some distinct drawbacks in that it isn’t as powerful as other data mining techniques, and there’s more of a chance of the system overheating. So it’s essential that you choose a powerful enough setup to serve your data mining purposes and has an effective enough cooling system to prevent any potential issues. One quality CPU setup that you can look into is the MSI MAG Series CORELIQUID 360R.

Operating Systems

And physical components are only part of the equation. As with any computer, in order to actually use it, you need to settle on an operating system. Let’s take a look at the options and how they measure up for crypto mining.

Top Operating Systems:

  • Windows
  • Ubuntu (Linux)
  • HiveOS
  • mining

While this list is far from comprehensive, it does cover some pros and cons of the most common operating systems employed on a build-your-own crypto rig. Let’s start with Windows 10. The latest version of Windows will support all hardware, drivers, and software while allowing you to run up to 12 graphics cards. Windows is free but demanding on computer resources.

Ubuntu (Linux) allows users to install up to 16 graphics cards, and it’s free, but there is a steep learning curve with few resources available for crypto mining applications. If you’re experienced with Linux systems, it can be a great choice. But for most beginner’s it’s more headache than it’s worth.HiveOS is another Linux-based OS that is a little more beginner-friendly. You can install this OS on 1-4 rigs for free. After that, you’ll pay a small commission. 

Mining is a Linux-based operating system built specifically for crypto mining, so it has a lot of pros. You’ll get a well-designed OS for one free worker. Additional workers can be added for a free. You will also need USB-Flash on 16GB for installation. And mining has somewhat limited functionality for monitoring mining rigs.

ETHOS was the first Linux-based OS to be specialized for crypto mining in 2016. Unfortunately, we have not seen an update since October 2018. The OS supports up to 20 miners, focusing on Etherum, and costs between 9-39 USD per month.

Application-Specific Integrated Circuit (ASIC)

ASIC crypto mining rigs are the most powerful option available for those truly dedicated to the crypto mining game. An application-specific integrated circuit is a small but powerful machine specifically dedicated to a single purpose. In this case, that’s mining crypto. However, these rigs are costly and should only be procured by serious crypto miners looking to get ahead in the game. Though, this can still be extremely difficult given that crypto mining companies can have hundreds of these systems working on their behalf to snatch up as many blocks as possible. It’s even gotten to the point that these companies are earning so much cryptocurrency that they’re undermining the very concept of decentralized currency. This has led to the development of specific “ASIC-resistant cryptocurrencies,” like Monero.

Suppose you’re looking to mind the big types of cryptocurrency, like Ethereum and Bitcoin, and are willing to invest in the crypto mining process. In that case, these are the rigs you definitely need to consider. Take a quick glance over a few of the options available on the market, such as the WhatsMiner ASIC or the AntMiner S9 ASIC Bitcoin Miner, to see which setup would be best for all of your crypto mining needs.

Lessons Learned from Building a Crypto Rig

Crypto mining draws a diverse crowd of enthusiasts ranging from beginners to technical geniuses. The good news is that it doesn’t take a particular level of technical skill to build a mining rig. Almost anyone can do it with a little planning and the right resources. As you are considering whether or not this is a project that you want to tackle, here are some lessons learned from those who have built their own mining rigs.

Commit More Time to Planning

Building a mining rig requires a lot of decisions that ultimately affect the success or failure of the rig. Unfortunately, those with limited technical knowledge will have a little more to learn. That only means that they should spend more time planning and researching before jumping in feet first. You’ll save a lot of frustration and money if you commit sufficient time to prepare before you begin buying components and trying to build a rig.

Track Expenses and Profits

The point of mining cryptocurrency is to make money. While it can be a fun hobby for some, keeping track of the money you put in is the only way to know where your break-even point is. Plus, the IRS considers cryptocurrency to be property, and gains are taxable–just like fiat currencies. While the IRS has been slower to catch up on enforcement of cryptocurrency taxes, the rules are clear, and the current popularity of this market has renewed their interest. 

Using Your Profits

The point of mining cryptocurrency is to make money. While you can stockpile your theoretical earnings in the digital world, selling or spending your profits is how you will actualize those gains. But make no mistake–the IRS has a claim to your crypto gains. You will pay taxes on these earnings just as you would any fiat currency. Luckily, the real world is leaning towards embracing cryptocurrencies. Major financial companies like Visa are investing heavily in crypto options, and you can now get a crypto debit card that spends just like your Platinum card.
