Bitcoin mining is referred to as the method of verifying Bitcoin transactions on the blockchain and generating new Bitcoin just like a central bank printing new fiat currency.

These are the other elements involved in Bitcoin mining as well as how Bitcoins are actually mined.

Understanding Blockchain and Bitcoin

Before understanding how Bitcoins are actually mined, it is important to understand the concept of blockchain and Bitcoin.

Consider blockchain as a central ledger where all cryptocurrency transactions are kept track of. A blockchain is a specific type of digital data structure that enables the sharing of a ledger of digital transactions among a distributed network of computers. In short, a blockchain is a way of digitally documenting data on a distributed ledger.

A blockchain network, which is the foundation of Bitcoin, is made up entirely of computers and typically stores and records transactions. Only after each block has been examined and approved by miners are transactions added to the blockchain. Since the transactions are now already on the blockchain, it is no longer possible to change them after this.

Digital currencies such as Bitcoin use the distributed ledger technology, which is a unique feature of blockchain technology as it ensures no records can be altered, and thus offers a much better transparency of transactions. The Bitcoin blockchain network uses the latest cryptographic algorithm techniques of SHA-256, which is responsible for converting the data into a unique string of characters.

What is Bitcoin Mining?

The process by which new bitcoins are placed into circulation is known as bitcoin mining. It is an essential part of the development and maintenance of the blockchain ledger and is also how the network confirms new transactions. “Mining” is performed using sophisticated hardware that solves an extremely complex computational math problem. The next block of bitcoins is distributed to the first computer to solve the issue, and the cycle repeats.

Mining for cryptocurrencies is time-consuming, expensive, and only occasionally profitable. However, due to the fact that miners are compensated in cryptocurrency tokens for their efforts, mining has a magnetic draw for many investors who are interested in cryptocurrencies. This may be because entrepreneurial types see mining as pennies from heaven, like California gold prospectors in 1849. Why not do it if you have a flair for technology?

The bitcoin reward that miners receive encourages people to help with the main goal of mining, which is to legitimate and oversee Bitcoin transactions in order to ensure their validity. Because many users all over the world share these responsibilities, Bitcoin is a “decentralized” cryptocurrency, or one that does not rely on any central authority like a central bank or government to oversee its regulation.

However, before you invest the time and equipment, read this explainer to see whether mining is really for you.

Key Takeaways

  • You can earn cryptocurrency through mining without having to pay any upfront costs.
  • Bitcoin miners receive bitcoin as a reward for completing “blocks” of verified transactions, which are added to the blockchain.
  • The miner who solves a difficult hashing puzzle first receives mining rewards, and the likelihood that a participant will find the solution is correlated with their share of the network’s overall mining power.
  • To set up a mining rig, you need either an application-specific integrated circuit (ASIC) or a graphics processing unit (GPU).

Throughout, we use “Bitcoin” with a capital “B” when referring to the network or the cryptocurrency as a concept, and “bitcoin” with a small “b” when we’re referring to a quantity of individual tokens.

Why Bitcoin Needs Miners

Blockchain “mining” is a metaphor for the computational work that nodes in the network undertake in hopes of earning new tokens. Actually, miners are essentially being compensated for acting as auditors. They are doing the work of verifying the legitimacy of Bitcoin transactions. This convention is meant to keep Bitcoin users honest and was conceived by Bitcoin’s founder, Satoshi Nakamoto.1 By verifying transactions, miners are helping to prevent the “double-spending problem.”

Double spending is the illegal use of the same bitcoin by the same Bitcoin owner twice. With physical money, this isn’t a problem: When you hand someone a $20 bill to buy a bottle of booze, you no longer have it, so there’s no chance you could use it to buy lottery tickets next door. Contrary to popular belief, it is not physically possible to spend the same dollar twice. With digital currency, however, as the Investopedia dictionary explains, “there is a risk that the holder could make a copy of the digital token and send it to a merchant or another party while retaining the original.”

Let’s say you had one legitimate $20 bill and one counterfeit of that same $20. If you were to try to spend both the real bill and the fake one, someone who took the trouble of looking at both of the bills’ serial numbers would see that they were the same number, and thus one of them had to be false. An analogous task is performed by blockchain miners, who examine transactions to make sure users haven’t attempted to spend the same bitcoin twice inadvertently. The reason why this isn’t a perfect analogy is explained in more detail below.

Only 1 megabyte of transaction data can fit into a single bitcoin block. Satoshi Nakamoto set the block size limit at 1MB, but this has caused controversy because some miners think it should be increased to accommodate more data. If so, the Bitcoin network would be able to process and verify transactions more quickly.

Types of Bitcoin Mining

There are various methods and forms of mining bitcoin that each produce varying amounts of hashing power and block rewards. Here are the various ways that one can mine Bitcoin:

CPU Mining

Central processing units (CPUs), also referred to as the brain of a computer and containing all the circuitry needed to process input and output results, were used to mine Bitcoin when it was first introduced in 2009 and for the first time. Because there were few miners and Bitcoin was still in its infancy, it was simple to mine bitcoins using CPUs in the early days.

GPU Mining

GPU mining gradually entered the scene as graphics processing units (GPUs) became more and more competitive as Bitcoin’s acceptance and popularity grew over time.

GPUs based systems, which are mainly used for gaming, modern video editing, proved to be more efficient for mining with better hash rate than CPUs. 2010 saw the introduction of the initial GPU mining software. However, Bitcoin GPU mining was only used for a brief period before being replaced by ASIC hardware by 2015.

ASIC Mining

ASIC, or application-specific integrated circuit, is a type of hardware made specifically for mining cryptocurrencies. It was launched in 2012, and proved to be 200 times more powerful than basic GPU miners. However, ASIC mining rigs are very expensive, with prices ranging from $2,000 to $15,000. Buying ASIC miners might be very expensive because of variable power consumption, fluctuating electricity costs, and network challenges. The two most widely used ASIC miner brands at the moment are Bitmain Antminer and MicroBT Whatsminer.

Buy Antminer S19 – Most Profitable Bitcoin Mining Rig

The Bitmain Antminer S19 series, Bitmain Antminer S17 series, and Bitmain Antminer S9 series are just a few of the new Bitcoin mining machines that Bitmain has released.

Another excellent option for Bitcoin mining is the MicroBT Whatsminer M20, Whatsminer M30, and Whatsminer M50 series.

FPGA Mining

Field-programmable gate arrays, also known as FPGAs, are faster and more cost-effective than ASIC and GPU mining, respectively. As opposed to ASIC miners, which are designed to be locked into mining a single coin or algorithm, FPGAs are able to maintain strong hashing power. The kind of hardware technology gives flexibility to the miner to reuse the set-up if they change your mining activity for something else. Crypto enthusiasts who don’t want to spend a fortune on mining equipment should consider FPGA miners.

Cloud Mining

This is the most recent method of mining Bitcoins, where the miner can purchase a contract from a cloud mining provider who specializes in cryptocurrency mining equipment or a cloud mining service. This enables the miner to mine bitcoins without having to pay the setup costs and maintenance costs associated with mining hardware. However, one must be extremely careful when selecting a reputable cloud miner in order to avoid any scams or frauds.

Why Mine Bitcoin?

In addition to lining the pockets of miners and supporting the Bitcoin ecosystem, mining serves another vital purpose: It is the only way to release new cryptocurrency into circulation. In other words, miners are basically “minting” currency. For instance, out of a total of 21 million bitcoins, there were just under 19 million in use as of March 2022.

All of those bitcoins were created by miners, with the exception of those that were created through the genesis block, the very first block that creator Satoshi Nakamoto created. The Bitcoin network would continue to function without miners, but no new bitcoins would ever be created. However, because the rate of bitcoin “mined” is reduced over time, the final bitcoin won’t be circulated until around the year 2140. This does not mean that transactions will cease to be verified. Miners will continue to verify transactions and will be paid fees for doing so in order to keep the integrity of Bitcoin’s network.

To earn new bitcoins, you need to be the first miner to arrive at the right answer, or closest answer, to a numeric problem. Proof of work (PoW) is another name for this procedure. For this proof-of-work activity to start, mining must be started in order to start looking for the solution to the puzzle.

There isn’t really any complex math or computation involved. You may have heard that miners are solving difficult mathematical problems—that’s true but not because the math itself is hard. What they’re actually doing is trying to be the first miner to come up with a 64-digit hexadecimal number (a “hash”) that is less than or equal to the target hash. Essentially, it is speculation.

Since there are trillions of different guesses that could be made for each of these problems, it is a matter of randomness, but it is still a very laborious task. Additionally, as more miners join the mining network, the number of potential solutions (also known as the level of mining difficulty) only grows. Miners need a lot of processing power to solve a problem first. To mine successfully, you need to have a high “hash rate,” which is measured in terms gigahashes per second (terahashes per second (TH/s) and gigahertz (GH/s).

Aside from the short-term payoff of newly minted bitcoins, being a coin miner can also give you “voting” power when changes are proposed in the Blockchain protocol. A Bitcoin Improvement Protocol (BIP) is what is used in this situation. In other words, miners have some degree of control over decisions regarding things like forking. You need to vote for these initiatives more often the more hash power you have.

How Much a Miner Earns

The rewards for Bitcoin mining are reduced by half roughly every four years.1 In 2009, when bitcoin was first being mined, one block would bring in 50 BTC. This was reduced to 25 BTC in 2012 by half. At 12.5 BTC in 2016, this had once more been cut in half. On May 11, 2020, the reward halved again to 6.25 BTC. You would have made $243,750 (6.25 x 39,000) for completing a block as of March 2022, when the price of Bitcoin was approximately $39,000 per bitcoin. Not a bad incentive to solve that complex hash problem detailed above, it might seem.

You can check the Bitcoin Clock, which continuously updates this information, to keep track of when these halvings will take place. It’s interesting to note that over the course of its history, the market price of Bitcoin has frequently tended to closely track the decline in the number of new coins put into circulation. Due to historically rising prices and increasing scarcity, the inflation rate’s decline increased the price.

Take Whatsminer M21S as an example:

[qn_miner id=”261″ field=”desc-profitability”]

The website CryptoCompare provides a helpful calculator that you can use to estimate how much bitcoin you could mine using your mining rig’s hash rate. Similar tools are available on other websites.

What You Need to Mine Bitcoins

Buy Whatsminer – A leading brand of mining hardware.

Earlier in Bitcoin’s history, it was possible for users to compete for blocks using a standard home computer, but this is no longer the case. The reason for this is that the difficulty of mining Bitcoin changes over time.

The Bitcoin network strives to have one block generated approximately every 10 minutes in order to ensure that the blockchain operates without a hitch and can process and verify transactions. However, if there are 1 million mining rigs competing to solve the hash problem, they’ll likely reach a solution faster than a scenario in which 10 mining rigs are working on the same problem. For that reason, Bitcoin is designed to evaluate and adjust the difficulty of mining every 2,016 blocks, or roughly every two weeks.1

When there is more computing power collectively working to mine for bitcoins, the difficulty level of mining increases in order to keep block production at a stable rate. The level of difficulty decreases as computing power is reduced. At today’s network size, a personal computer mining for bitcoin will almost certainly find nothing.

Mining Hardware

All of this means that miners must now make investments in high-end computer hardware like a graphics processing unit (GPU) or, more realistically, an application-specific integrated circuit (ASIC) in order to mine effectively. These can cost anywhere from $500 to several thousand dollars. Some miners, especially Ethereum miners, purchase individual graphics cards as a cheap way to put mining operations together.

ASIC machines, which in this case are designed specifically to mine bitcoins, make up the majority of today’s bitcoin mining equipment. Today’s ASICs are many orders of magnitude more powerful than CPUs or GPUs and gain both more hashing power and energy efficiency every few months as new chips are developed and deployed. With just 27.5 joules per terahash, modern miners can produce close to 200 TH/s.

An Analogy

Let’s imagine that after telling three friends that I’m thinking of a number between one and 100, I write that number down on a piece of paper and enclose it in an envelope. My friends just have to be the first to guess any number that is less than or equal to the given number. They don’t even have to guess the exact number. They can make as many guesses as they want, with no upper limit.

Let’s say I’m considering the number 19. Because 21 > 19, if Friend A guesses 21, they lose. In the event that Friend B guesses 16 and Friend C guesses 12, they have both theoretically arrived at workable solutions because 16 19 and 12 19 respectively. There is no “extra credit” for Friend B, even though B’s response came closer to the desired outcome of 19 than did B. Now imagine that I pose the “guess what number I’m thinking of” question, but I’m not asking just three people, and I’m not imagining a number between 1 and 100. I’m thinking of a 64-digit hexadecimal number instead, and I’m asking millions of would-be miners. You can now see that it will be very challenging to make the correct guess. The system collapses if B and C give their responses at the same time.

Although there are frequently multiple correct answers in the context of Bitcoin, ultimately there can only be one. The Bitcoin network will choose which miner to honor by a simple majority of 51 percent when multiple concurrent answers are given that are equal to or less than the target number.

Usually, the miner who has worked the hardest or, to put it another way, the one who has verified the most transactions, wins. The losing block then becomes an “orphan block.” A block that is not added to the blockchain is an orphan block. Miners who successfully solve the hash problem but haven’t verified the most transactions are not rewarded with bitcoin.

The Mining Process

What is a ’64-Digit Hexadecimal Number’?

Here is an example of such a number:

0000000000000000057fcc708cf0130d95e27c5819203e9f967ac56e4df598ee

There are 64 digits in the number above. So far, comprehension isn’t too difficult. As you probably noticed, that number also includes letters from the alphabet in addition to numbers. Why is that?

To understand what these letters are doing in the middle of numbers, let’s unpack the word “hexadecimal.”

The decimal system uses factors of 100 as its base (e.g., 1% = 0.01). This, in turn, means that every digit of a multi-digit number has 100 possibilities, zero through 99. In computing, the decimal system is simplified to base 10, or zero through nine.

“Hexadecimal,” on the other hand, means base 16 because “hex” is derived from the Greek word for six, and “deca” is derived from the Greek word for 10, which has a hexadecimal system with 16 possible digit combinations. However, our numeric system only supports ten different ways to represent numbers (zero through nine). You must therefore add letters, specifically letters A, B, C, D, E, and F.

The hash’s total value, which is a 64-digit number, does not need to be determined if you are mining bitcoin. I’ll say it again: You don’t have to figure out a hash’s total value.

What Do ’64-digit Hexadecimal Numbers’ Have to Do With Bitcoin Mining?

Do you recall the analogy where the number 19 was written on a piece of paper and placed in a sealed envelope? The metaphorical unpublished number in the envelope is known as the target hash in the context of bitcoin mining.

Miners are making educated guesses about the target hash using those massive computers and numerous cooling fans. Miners make these guesses by randomly generating as many “nonces” as possible, as quickly as possible. A nonce is short for “number only used once,” and the nonce is the key to generating these 64-bit hexadecimal numbers As I keep mentioning, a nonce in Bitcoin mining is 32 bits in size, which is considerably less than the hash, which is 256 bits. The credit for finishing that block and 6.25 BTC are given to the first miner whose nonce generates a hash that is less than or equal to the target hash.

Although rolling a 16-sided die 64 times to generate random numbers theoretically could lead to the same result, why on earth would you want to do that?

The screenshot below, taken from the site Blockchain.info, might help you put all this information together at a glance. You are viewing a summary of everything that occurred during the mining of block No. 490163. The nonce that generated the “winning” hash was 731511405. The target hash is displayed at the top. The term “Relayed by AntPool” refers to the fact that this particular block was completed by One of the more popular mining pools is AntPool (more on mining pools below).

As you can see, they contributed to the Bitcoin community by validating 1,768 transactions for this block. If you really want to see all 1,768 of those transactions for this block, go to this page and scroll down to the Transactions section.

How Do I Guess at the Target Hash?

A line of leading zeros appears at the start of every target hash. Although there isn’t a minimum target, the Bitcoin Protocol has set a maximum target. No target can be greater than this number:

00000000ffff0000000000000000000000000000000000000000000000000000

A hash that has at least the minimum amount of leading zeroes specified by the mining difficulty is the one that a bitcoin miner will be able to successfully mine.

Here are some examples of randomized hashes and the criteria for whether they will lead to success for the miner:

You must purchase a quick mining rig or, more realistically, join a mining pool, which is a collection of Bitcoin miners who pool their computing power and divide the generated Bitcoin, in order to find such a hash value. Mining pools are comparable to Powerball clubs whose members buy lottery tickets en masse and agree to share any winnings. Instead of individual miners, mining pools produce a disproportionately large number of blocks.

In other words, it’s literally just a numbers game. You cannot guess the pattern or make a prediction based on previous target hashes. At today’s difficulty levels, the odds of finding the winning value for a single hash is one in the tens of trillions.6 Even with a mining rig that is extremely powerful, the odds are not favorable if you are working alone.

In addition to the high cost of the expensive equipment needed to have a chance of succeeding in a hash problem, miners must also take into account the significant amount of electricity that mining rigs use to produce the vast quantities of nonces necessary to find the answer. All things considered, most individual miners are currently largely losing money when mining bitcoins. You can enter information like your hash rate and electricity costs into the helpful calculator on the website CryptoCompare to get an idea of the costs and benefits.

What Are Mining Pools?

The miner who discovers a solution to the puzzle first receives the mining rewards, and the probability that a participant will be the one to discover the solution is equal to the proportion of the total mining power on the network.

A small number of participants have a very slim chance of independently finding the upcoming block. For instance, a mining card that one could purchase for a couple of thousand dollars would represent less than 0.001% of the network’s mining power. With such a small chance at finding the next block, it could be a long time before that miner finds a block, and the difficulty going up makes things even worse. The miner might never get their money back. The solution to this issue is mining pools.

Third parties manage mining pools, which assemble miner groups. Miners are able to receive a consistent supply of bitcoin from the moment they turn on their miners by cooperating in a pool and splitting the payouts among all members. On Blockchain.info, statistics on a few of the mining pools are available.

A Pickaxe Strategy for Bitcoin Mining

As mentioned above, the easiest way to acquire Bitcoin is to simply buy it on one of the many Bitcoin exchanges. Alternately, you can always leverage the “pickaxe strategy.” This is based on the adage that during the California Gold Rush of 1849, manufacturing the pickaxes used in mining was a wiser investment than panning for gold.

To put it in modern terms, invest in the companies that manufacture those pickaxes. An organization that produces tools used for Bitcoin mining would be the pickaxe’s cryptocurrency equivalent. You may consider looking into companies that make ASIC equipment or GPUs instead, for example.

Downsides of Mining

The risks associated with mining are frequently monetary and legal. As mentioned, mining involves a risk in terms of money because one might spend time and money buying mining equipment costing hundreds or thousands of dollars only to see no return on their investment. That being said, joining mining pools can help to reduce this risk. You should think twice if you want to mine but live in an area where it is illegal. It may also be a good idea to research your country’s regulation and overall sentiment toward cryptocurrency before investing in mining equipment.

A further potential danger stemming from the expansion of Bitcoin mining (and other PoW systems as well) is the rising energy consumption of the computer systems that power the mining algorithms. Though microchip efficiency has increased dramatically for ASIC chips, the growth of the network itself is outpacing technological progress. As a result, there are concerns about Bitcoin mining’s environmental impact and carbon footprint.7

However, there are initiatives to reduce this unfavorable externality, including the use of carbon offsets and the search for more environmentally friendly and cleaner energy sources for mining operations (such as geothermal or solar sources). Another approach is to switch to less energy-intensive consensus mechanisms, such as proof-of-stake (PoS), which Ethereum has adopted. However, PoS has its own set of flaws and inefficiencies, including a risk of consensus control centralization and an incentive for hoarding rather than using coins.

Because mining requires (computational) work, much like mining for gold or silver does, it can be thought of as the process of adding new bitcoins to the system. The tokens that miners discover are, of course, virtual and only exist within the blockchain’s digital ledger.

Why Do Bitcoins Need to Be Mined?

There is a chance that someone could copy, counterfeit, or use the same coin more than once because they are entirely digital records. Mining solves these problems by making it extremely expensive and resource-intensive to try to do one of these things or otherwise “hack” the network. Indeed, it is much more economical to become a miner on the network rather than to try to undermine it.

How Does Mining Confirm Transactions?

In addition to adding new Bitcoin to the market, mining is essential for validating and confirming fresh transactions on the Bitcoin blockchain. This is significant because no single body, be it a bank, court, government, or anything else, decides which transactions are legitimate and which ones are not. Instead, a decentralized consensus is reached through mining using proof of work (PoW).

Why Does Mining Use So Much Electricity?

Anyone could easily run a mining program from their computer or laptop in the early days of Bitcoin. However, the difficulty of the mining algorithm increased as the network grew larger and more people became interested in mining. This is because the code for Bitcoin targets finding a new block once every 10 minutes, on average.1

The likelihood that someone will find the correct hash sooner rises as the number of miners increases, which makes it harder to achieve the original 10-minute goal. Imagine if the network’s mining capacity increased by thousands or even millions of times. There are a lot of new machines using that much energy.

The Bottom Line

Bitcoin “mining” serves a crucial function to validate and confirm new transactions to the blockchain and to prevent double-spending by bad actors. New bitcoins are also added to the system in this manner. The task involves producing proof of work (PoW), which is inherently energy-intensive and is based on a challenging puzzle. However, this energy is embodied in the value of bitcoins and the Bitcoin system, which maintains the stability, security, and reliability of this decentralized system.

All you need to start mining in Etherium is an AWS EC2 instance.

You have probably heard something about the rapidly growing popularity of cryptocurrencies. Slowly but surely, cryptocurrencies are changing the way financial systems and transactions work (in my opinion, such systems should continue to work, assimilating with new trends).

Not so long ago the value of Bitcoin reached $6000, at that the market capitalization of this cryptocurrency now amounts to $103 billion, as well as hundreds of ICOs (Initial coin offering) performed since August of this year. Needless to say, there has been a huge economic boom in the Bitcoin world during this time, which will probably not subside anytime soon.

As you can see in the chart below, the total capitalization of cryptocurrencies has grown from $50 billion to $150 in just one year.

Personally, I like the Ethereum project best, where it’s easy enough to start mining using AWS. I want to dedicate this article to this very topic – mining.

Before we get to the main topic, I suggest that we first get acquainted with the basic concepts. In case you already know about this platform and mining, you can safely skip the introductory part.

What is Etherium?

Etherium is an open, blockchain-based software platform that allows developers to create and deploy decentralized applications. The main advantage of Etherium over Bitcoin is that the former provides support for various types of decentralized applications.

Etherium ranks second after Bitcoin in terms of market capitalization scale. For example, in the past year alone, the value of the Etherium platform has increased by 230%, as seen in the chart below:

Nevertheless, the increase in price growth implies an increase in the demands placed on the miners who work on the Etherium platform, which in turn inevitably leads to an increase in the complexity of the mining process:

If it just so happens that you started working with the Etherium platform in May of this year, you’ve probably felt how much more complicated the mining process has become today.

What is crypto-mining?

The word “mining” itself is a kind of analog of gold mining in the field of cryptocurrencies. In a nutshell: mining cryptocurrencies is solving complex mathematical problems. Miners, in turn, are people who spend all their time and energy on solving such problems. Miners provide their solutions to those who validate such solutions. The miners then receive a well-deserved reward: a block of Ether. As you might have guessed by now, the more complex the mining process, the more complex the mathematical problems that need to be solved become, and the harder it is to get the reward for the solutions found. At the moment, due to the extraordinary popularity and demand for Etherium, the complexity of mining for this platform is also reaching its maximum.

Is it even worthwhile to engage in mining in Etherium?

As it happens, the more miners join Etherium, the more difficult the task and the process of mining itself becomes. Then you ask, “Well, should I even start mining if the time for a good start has already been missed?” You should know that the value of the platform is constantly increasing, so the value of its currency, however small, could grow to enormous proportions in the future.

However, there have been some changes in Etherium: not so long ago, the proof-of-stake method was introduced for this platform. This means that the process of mining will not mean much anymore. Nevertheless, such innovations can lead to a sharp increase in the value of the cryptocurrency Etherium.

So, if you have had a chance to rethink all of the above information and are still ready to mine Etherium, then the rest of this article is just for you!

How do I run my own AWS instance for mining?

Just a few simple steps:

  1. Go to your AWS EC2 console and change your region to US East (N.Virginia) . This county has the lowest cost for the services we need, and it also has an AMI community where we can find the mining libraries we need installed.
  2. Under Instances, select Spot Instances and click Request Spot Instances.
  3. Find an AMI community called ami-cb384fdd and select it.
  4. Under the Instance column, select g2.8xlarge.
  5. Run it!

Getting started with mining


In order to start mining, you need your own Etherium wallet and you must be part of a pool of miners. 
To create your wallet, go to www.myetherwallet.com and follow the instructions given. Once the registration process is complete, you will receive the address of your personal wallet.


For mining, we will use the Dwarfpool pool,. However, you can use any other pool. Here you can find a list of the most popular ones.

Just use SSH for this purpose and enter the following code:

> tmux
> ethminer -G -F http://eth-eu.dwarfpool.com/{WALLET ADDRESS}/{YOUR_EMAIL ADDRESS} --cl-local-work 256 --cl-global-work 16384


With Tmux you can continue to perform all necessary processes even after the SSH connection has ended.

Ethminer is a GPU miner. Enter your e-mail address to receive notifications about payments made in the platform. Other settings are provided to optimize the mining process.

That’s all!


Soon the DAG-file will be created and right after that you can start mining.

My opinion is: due to its excessive complexity the process of mining in Etherium is not worth the candle if you decide to do it just now. For instance, one hour of g2.8xlarge will cost you $2.6, and the profits of an Etherium miner can also be as low as $2.6 per day!

Now no one can tell you for sure what the future holds for any of the current cryptocurrencies – maybe they will all burst like a bubble. There is also an opinion that selling cryptocurrency is a kind of lottery.

Nevertheless, being an optimist, I am more than confident that cryptocurrencies have a great future ahead, and the recent rapid development of Bitcoin and Etherium only confirms my assumptions. We should also not forget that mining is like a lottery, so a unit of cryptocurrency earned today can go up in value a hundred times in a year.

The plunge in the price of these assets in recent months prompted those who bet on graphics cards – used for their power and ability to perform complex calculations to increase profits in the mining of these assets – to sell them below their price in order to recover part of the investment.

Cryptocurrency miners began auctioning off their graphics cards (GPUs) en masse due to the steep drop in the value of this asset class in recent months.

For much of 2021, cryptocurrencies had a good time and reached record highs, fueling the mining process and the purchase of graphics cards, which rose in price in the face of higher demand and their stock levels faltered at times.

However, the downward trend since last November has dragged down the most popular cryptocurrencies, such as Bitcoin and Ethereum, which have lost more than half of their value so far this year, according to DPA agency on Friday.

The sharp decline in cryptocurrencies thus dragged down GPUs that miners employ for their power and ability to perform complex calculations to amplify profits in the mining of these assets.

It is sold en masse mainly in China, where miners have taken advantage of cheaper electricity prices.

On Xianyu, a second-hand marketplace similar to Ebay, Nvidia RTX 3080 graphics cards are offered at 3,500 yuan (equivalent to €496.60), according to Twitter account “I_Leak_VN”

This figure contrasts with the 759 euros it costs on Nvidia’s official website, where it appears to be out of stock.

Other miners are resorting to resale via streaming to get rid of more of these GPUs, according to Baidu, the Asian powerhouse’s equivalent of Google.

The prices of these graphics cards, which in this case are Nvidia’s RTX 3060, range from €285 to €332, figures below the €439 official retail price.

Nasdaq-listed Bitcoin miner Core Scientific has filed for Chapter 11 bankruptcy, citing low Bitcoin prices and high costs.

Core Scientific, one of the largest Bitcoin miners in the industry, announced today that it has filed for Chapter 11 bankruptcy protection in Texas.

Importantly, the miner will continue operations during this process, and that it “expects to enter into “Restructuring Support Agreement” with the Ad Hoc Shareholders Group, which represents more than 50% of the holders of its convertible notes.”

The shareholder group will also provide up to $56 million in financing as part of a debt recovery facility “to provide the necessary funding to carry out the planned restructuring.”

The news comes amid the current bear market, which has seen the price of Bitcoin fall by more than 60% so far this year. This, coupled with rising energy prices and the increasing difficulty of mining the asset, which earlier this week rose another 3%, means miners need to allocate more resources to produce the same amount of coins as before.

The Austin-based company announced it would go public through a special purpose acquisition vehicle, or SPAC, in July 2021, with the company’s shares trading on the Nasdaq in January 2022.

However, Core Scientific has seen its shares plunge 98% in 2022 to date. Although the company continues to generate cash flow, its equipment financing obligations are said to far exceed revenues.

The company’s market capitalization fell from $4.3 billion in July last year to $78 million at Tuesday’s close.

Core Scientific did not immediately respond to a request for comment from Decrypt.

Is Core Scientific’s bankruptcy unexpected?

The company, which also has operations in North Dakota, North Carolina, Georgia and Kentucky, first warned of possible bankruptcy in October of this year, saying it was exploring several options.

“Given the uncertainty about the company’s financial condition, there are substantial doubts about its ability to continue as a going concern for a reasonable period of time,” Core said at the time.

Court documents from bankrupt cryptocurrency lender Celsius also revealed that it owes Core Scientific millions of dollars in unpaid electricity fees. According to the firm, it is losing approximately $53,000 a day to cover what Celsius has refused to pay.

Earlier this month, Core received a $72 million offer from one of its major lenders, B. Riley, which stated that “bankruptcy is absolutely not necessary” for the company and that “the vast majority of Core Scientific’s problems are self-imposed and can be corrected with open and transparent discussion and continued engagement” with its lenders and investors.

The investment bank proposed a new financing plan, which was to provide non-cash payment funds on favorable terms with an extension of more than two years for Core Scientific to reach profitability.

Although Core would be the first publicly traded company to file for bankruptcy, it is not the first victim of industry turmoil.

Bitcoin mining data center company Compute North filed for bankruptcy in September, claiming it owed as much as $500 million to at least 200 creditors. Rival companies Riot Blockchain (RIOT) and Marathon Digital Holdings (MARA) are staying afloat; however, their shares are down 83% and 88% this year, respectively.

MicroBT has unveiled new Whatsminers at the Bitcoin 2022 conference. One of them is even supposed to be water-cooled.

Chinese mining equipment manufacturer MicroBT is introducing new ASICs at the Bitcoin 2022 Conference.

The new generation devices are called M50, M50s and M53 and should be available soon.

In terms of energy efficiency, the new devices can definitely compete with the flagships of the competition. Accordingly, the WhatsMiner M50S achieves 126 terahashes per second (TH/s) with an energy efficiency of 26 joules per terahash (J/T). The M50 performs 114 TH/s at 29 J/T.

The M53 has not yet been specified in detail in terms of efficiency. However, it is said to be a water-cooled ASIC. Due to the special cooling, the rig is supposed to achieve an impressive 226 TH/s and is thus in direct competition with the Antminer S19 XP Hyd. that costs just under $20,000 and achieves 255 TH/s on the road.

Here are the detailed parameters about Antminer S19 XP Hyd
