Many people believe crypto is the future and a viable path toward financial independence with large numbers interested in mining the currency to generate income.

Logical considering in a single day in 2021, crypto mining reportedly generated a staggering $63 million.

But is crypto mining legal? Is it still profitable and if it is, what is the most profitable?

If you are new to crypto mining, it’s common to use a gaming computer with a GPU to get your feet wet. But are you risking damaging the GPU?

In this post, I dig in and answer these and many other crypto mining-related questions.

Let’s dig in (pun intended).

In This Post:

1) Is Crypto mining still profitable?

Yes! It’s very profitable if you have enough computing power. If you want to make money from mining, you need to invest in hardware (CPU/GPU) and software (mining pool). You can mine Bitcoin, Ethereum, Litecoin, Dash, Monero, Zcash, etc. There are two main types of cryptocurrency mining: Proof of Work (PoW) and Proof of Stake (PoS). PoW requires users to solve complex mathematical problems, while PoS allows users to stake coins and receive rewards without solving those problems.

Proof of work (PoW) is the oldest consensus algorithm used in blockchain technology. It was first implemented in 2009 by Satoshi Nakamoto in Bitcoin. Since then, it has been adopted by numerous cryptocurrencies, including Ripple, Monero, Dash, Zcash, Komodo, etc. In PoW, miners compete against each other to add transactions to the blockchains. Miners who find solutions to cryptographic puzzles are rewarded with new coins. These coins are called ‘Block Reward,’ and the puzzle is known as “Proof of Work.”

To mine bitcoins, one needs to use computing power to compete with all other miners to solve the Proof of work problem. While Proof of stake, on the other hand, does not require solving any puzzle, it relies on the participants to contribute to the network’s security.

In PoS, there is no competition among miners because everyone agrees on the same rules. Instead, miners must lock up some coin tokens in exchange for participating in the network. Once you lock your coins, you cannot change your mind later and decide to unlock them. If you fail to meet this requirement, you lose your locked coins forever.

In the mining process, your computer will generate hashes used to verify transactions on the blockchain. The more hashes you generate, the higher your chance of finding a block. Once you find a block, you receive a reward in the form of Bitcoins or other cryptos.

2) Is Crypto mining illegal?

The legality of crypto mining depends on where you live. Some countries like China, India, Iran, North Korea, Russia, Saudi Arabia, Turkey, Venezuela, Zimbabwe ban crypto mining completely. Others like Australia, Canada, Japan, New Zealand, Singapore, South Africa, United States allow it but with restrictions.

For example, you may be required to pay taxes in some cases. Also, in some jurisdictions, crypto mining is considered gambling. So, you should check local laws before starting crypto mining. The concept of Bitcoin can be usual to understand. But, let us start with understanding how does bitcoin works? For instance, virtual currencies are created when users solve complex mathematical problems using their computers.

These problems are referred to as “cryptographic puzzles.” To create a puzzle, a user must first choose a number between 1-9. Then, they have to pick another number between 1-9 and multiply it by a third number. After that, the user adds all three numbers together. Finally, the user divides the sum by 17. The result is the cryptographic hash value. A user who solves the puzzle gets rewarded with bitcoins.

3) Which Crypto mining is most profitable?

Bitcoin is currently the largest cryptocurrency. That means it has the highest market cap. However, it is not always the best option. Many altcoins offer better returns than Bitcoin. Here are some examples:

Ethereum: ETH is the second-largest cryptocurrency after Bitcoin. It was launched in 2015 and is based on the Ethereum platform. Ethereum offers smart contracts functionality. Smart contracts are programs that run exactly as programmed without requiring human intervention. They enable peer-to-peer payments, decentralized applications, and secure exchanges.

Litecoin: LTC is one of the oldest cryptocurrencies. It was founded in 2011 and is based on the Litecoin platform. Litecoin is faster than Bitcoin and aims to provide smaller payments per transaction. 

Monero: MXR is a privacy-oriented cryptocurrency. It was launched in 2014 and is based on the Cryptonote protocol. Unlike traditional cryptocurrencies, Monero uses ring signatures for anonymity. It makes it ideal for sending funds anonymously.

Dash: DASH is designed to provide fast and private transactions. It was launched in January 2014 and is based on Darkcoin technology. Like Monero, Dash also uses ring signatures for anonymity and zero-knowledge proofs for security.

It is important to note other cryptocurrencies such as Ripple, Zcash, Dogecoin, etc. These coins have different features from each other. You need to do your research to determine which one suits your needs.

4) Is Crypto mining dangerous?

Yes, it is very risky. If you lose access to your computer, you will lose your entire investment. In addition, if your computer crashes while mining, you could lose everything. Therefore, make sure you backup your wallet regularly. However, there are various risks associated with Crypto mining that include;

1) High electricity costs.

2) Low return rates.

3) Lack of support from banks.

4) Risk of losing money due to hacking attacks.

5) Difficulty finding new blocks.

6) Loss of power during storms.

7) Theft of hardware components.

You should note that these risks are minimized through careful planning. For example, you can reduce the risk of theft by using a safe place to store your hardware. Also, you can use a reliable internet connection so that you don’t lose power when storms hit.

5) What is the best Crypto mining software?

The best crypto mining software is the one that allows you to mine multiple currencies simultaneously. Some popular ones are Ethminer, CGMiner, BFGMiner, and Slush pool. The following table shows how they compare.

Currency Name


On this platform, you can mine up to three cryptocurrencies simultaneously. It supports Windows, Linux, Mac OSX, Android, iOS, and Raspberry Pi platforms. It comes with a built-in graphical user interface (GUI). Instant payouts are a feature of Ethminer (Bitfly). It also features a Discord channel where miners can discuss things which is helpful for people who are new to mining crypto.

This platform supports Windows, Linux, and Mac OSX operating systems. It does not come with a GUI. Instead, you need to download an application called “bfgminer.” You can then configure bfgminer using a text file. It charges a specific 1% fee for every block mined.


This platform supports Windows and Linux platforms. It comes with both a GUI and command-line interface. It requires users to write their scripts to generate hashes. It supports several types of GPUs, including NVIDIA GeForce GTX 1050 Ti, 1070, 1080, and AMD Radeon RX 460, 570, 580, and Vega 56/64.


This platform supports Windows only. It doesn’t require any extra software. It automatically detects all available GPU devices and starts mining automatically. It also offers a built-in GUI.

It is a very modern-looking platform that looks like a web browser. It supports Windows, macOS, and Linux operating systems. You can mine ETH, EOS, LTC, MXR, DASH, BCH, BTC, and many others. It uses the same configuration files as ethminer.

Minimum payouts for each coin are as follow:

ETH – 0.000819 USD per day

Ravencon – 0.001250 USD per day

Beam -0.0125 USD per day

EOS – 0.000160 USD per day


Stormgain is one of the simplest platforms. All you have to do is enter your email address and password. Then select your desired coins and start mining. It supports Windows, Mac, and Linux operating systems and more than 30 different coins. It is easy to install and use. Stormgain is suitable only if you are experienced in cryptocurrency mining. For starters, mining is done in four-hour shifts. So, every four hours, you must click to activate the miner. It means that you will earn less money compared to other platforms. But it is still better than nothing.


Slushpool is another simple platform. You just need to enter your email address and choose which currency you want to mine. It supports Windows, MAC, Linux operating systems, and more than 20 different coins. For using SlushPool’s platform, a 2% pool fee is charged. Some supported ASIC miners also provide a 0% pool fee option.

Mining pools charge fees to cover infrastructure costs such as electricity bills. These fees help keep the price of Bitcoin stable. Fees vary depending on the type of miner used. If you decide to join a pool, make sure that it pays out at least 75% of its revenue back to its members. It will ensure that you receive a fair share of the reward.

Many other platforms allow you to mine cryptocurrencies. However, we recommend using the ones mentioned above because they are relatively easier to use. They are also free to try out. If you decide to buy a miner, make sure it is compatible with the operating system you are running on. It will help ensure that you get the most from your investment.

6) How much does a crypto mining rig cost?

A good crypto mining rig costs between $500 and $1,200. It depends on the type of hardware used, its efficiency, and the number of rigs you want to run simultaneously. A cheap rig may work fine but won’t compete with a high-end rig. The price varies from different components for instance;

CPU – $100-$300

GPU – $150-$600

Power supply – $30-$80

Memory – $20-$40

Hard drive – $10-$15

The best way to find out how much a rig cost is by contacting manufacturers directly or visiting online forums.

7) Does Crypto mining damage your GPU?

Yes, it does. Mining uses a lot of power which causes heat to build up inside your computer. Over time, this can cause irreversible damage to your graphics card. That’s why we suggest buying a quality cooling unit. 

The energy consumption of mining varies depending on what kind of machine you choose. For example, a CPU miner consumes less electricity than a GPU miner. However, there are ways to maintain your GPU without damaging it.

You can lower the temperature of your GPU by lowering the speed at which you mine. It will reduce the amount of heat generated by your GPU. If you don’t want to lower the speed, you should consider investing in a fan. Fans keep cool air circulating your GPU. This prevents overheating.

You can also use an external cooler. These are usually designed to fit over the top of your GPU. They provide better airflow and prevent overheating.

Also, check the GPU BIOS settings. There might be some options that can help you control the temperature of your GPU. The various optimizations for reducing memory timings and clock speeds are available in the BIOS. 

One can also check for overclocking features in the BIOS. Some GPUs come with built-in overclocking support. You can enable these features to increase the performance of your GPU. It is important to note that overclocking can lead to irreparable damage to your GPU. Therefore, you should always use an external cooler when overclocking.

The hashing power is measured in TH/S (terahashes per second). Which is the rate at which your GPU processes data. The higher the hash rate, the faster your GPU will process data. The specifications of your GPU determine hashing power.

8) What is the best graphics card for crypto mining?

It depends on what you intend to do with your GPU. Do you plan to mine only one cryptocurrency or multiple? What is your budget? And what is your goal? The more powerful the GPU is, the more efficient it will be. So if you have a limited budget, go for something like an Nvidia GeForce RTX 3060 Ti. But if you have a large budget, you can opt for an AMD Radeon RX 5700 XT.

The Nvidia GeForce RTX 2080 Ti was the undisputed king of GPUs not long ago if you want 4K gaming or incredibly smooth ray tracing on high settings. In terms of mining performance.

If you’re looking for a GPU for mining Monero, I recommend the Nvidia GeForce GTX 1080 Ti.

 Its hash rate is 32.76 MH/s, which makes it a good option for those who want to start mining Monero right away. That is, if you can afford the exorbitant price, this is a considerable entry barrier.

If you are planning to mine several cryptocurrencies, you need to make sure that you get a GPU that supports them. Otherwise, you will end up wasting money. Also, try to avoid using older hardware versions as they may not offer the same efficiency level.

When it comes to 1440p gaming, the AMD Radeon RX 5700 XT is a complete beast. Not only does it have great 1440p gaming performance, but its hash rate is impressive too. At 29.6 MH/s, it is the highest performing GPU for crypto mining. However, it costs quite a bit more than other cards.

. On the other hand, MSI Gaming GeForce RTX 2070 has a lower hash rate of 25.7 MH/s. But it offers excellent 1440p gaming performance. It is cheaper than the previous model, which could be a good choice for someone just starting.

For 1080p gaming, the Nvidia GeForce RTX 3060 Super is a better pick. It has a hash rate of 24.9 MH/s. It is slightly less expensive than the RTX 2060 Super. But it doesn’t have any extra features to justify the cost difference.

9) Does CPU affect crypto mining?

Yes, it does. A lot! CPUs are much slower than GPUs when it comes to processing data. They also consume more energy. Therefore, they are generally used for web browsing, video editing, etc.

CPUs are usually paired with dedicated graphics cards for mining purposes. Because of this, they don’t provide any advantages over regular computers. As a result, GPUs are considered superior in terms of mining power.

10) What is a Crypto-mining farm?

A crypto mining farm is a group of computers that work together to solve cryptographic puzzles. These puzzles are part of verifying transactions in an online currency. Once the puzzle is solved, the miner gets rewarded with coins.

Crypto mining farms work by solving complex mathematical problems. It requires a large amount of computing power. So, people use specialized hardware like ASICs (Application Specific Integrated Circuits).

Miners have to solve difficult adjustments before adding a transaction to the blockchain. The difficulty adjusts itself automatically based on how many miners there are. It ensures that the reward stays constant.

The first cryptocurrency that used proof-of-work was Bitcoin. Since then, many others have been created. Each one uses different algorithms. Some even require a combination of both Proof-of-Work and Proof-of-Stake.

11) Are crypto mining contracts worth it?

Contract mining is a type of cloud mining where users pay upfront for access to the network’s hashing power. Users can earn rewards based on the number of hashes performed per second.

This method of earning is very similar to traditional cloud mining. However, because the contract is paid upfront, it eliminates the risk of investing money without knowing the return.

Yes, crypto mining contracts are worth it because;

1. You get to mine at your own pace

2. You know exactly how much you will make each month

3. You can start small and gradually increase your investment

4. There is no need to worry about electricity costs or maintenance fees

Bitcoin Mining Contracts, for instance, offer a fixed monthly payout rate. If you invest $100 today, you’ll receive $10 back after 1 year. One has to have a reliable mining pool to ensure that they’re not left out of the action.

12) How much electricity does crypto mining use?

Mining cryptocurrencies takes a lot of computing power. It consumes more electricity than most countries. According to estimates, the average household in the United States uses roughly 100 watts of electricity to keep their home warm.

However, the same amount of electricity could power around 50 homes for a whole day. That means that if every American household switched to using renewable energy sources, we would save enough electricity to power all US households for a full year.

Bitcoin mining, for instance, consumes between 0.5 – 3 kilowatts of electricity, depending on which algorithm you choose. The cost of this electricity where vary from one location to the next and is likely to increase as demand continues to increase. So, if you want to profit from this trend, you should consider buying some Bitcoin mining contracts.

Bitcoin mining has grown into its sector due to rising competitiveness, necessitating specialized machines, servers, and massive data centers with sufficient thermal efficiency to keep the computers from overheating.

So, yes, crypto mining is bad for the environment. But, it’s also good news! It shows us that we have the technology to create clean energy. And as long as we continue to innovate, we can reduce our reliance on fossil fuels.

13) Is AMD good for Crypto mining?

AMD is a company that manufactures graphics cards. They’ve recently started producing CPUs (Central Processing Units) for crypto mining. It is great news for those who prefer to mine with GPUs rather than CPUs.

CPUs are generally slower than GPUs, but they don’t require cooling systems. As such, they consume less electricity.

AMD’s new CPUs are designed specifically for mining purposes. The company claims that these chips are 10 times faster than the previous generation.

If you’re looking for a GPU that’s suitable for crypto mining, check out the Antminer S9 by Bitmain. If you’re looking for a GPU that’s suitable for crypto mining, check out the Antminer S9 by Bitmain. AMD’s make perfect graphic cards like the RX 580 and the R9 Nano. 

It is important to note that other companies produce ASIC-based miners. These devices are extremely efficient at mining cryptocurrency, but they are expensive and difficult to obtain.

Wrapping Up

Crypto mining is an interesting way to earn money while contributing to blockchain technologies. However, it’s important to be aware of the environmental impact of this activity. By understanding how much energy is consumed when mining different coins, you’ll be able to decide whether or not it makes sense for you to invest your time and resources in this field.
