Mining for cryptocurrency is painstaking, expensive, and only sporadically rewarding. Nonetheless, since miners are compensated for their work with crypto tokens, mining has a magnetic attraction for many investors involved in cryptocurrencies. This may be because, like California gold prospectors in 1849, entrepreneurial styles regard mining as pennies from heaven. And if you have a technical inclination, why not do it?

You can gain cryptocurrency by mining without having to put down cash for it.

As a reward for completing 'blocks' of checked transactions applied to the blockchain, Bitcoin miners earn Bitcoin.

Mining rewards are charged to the miner who first discovers a solution to a complex hashing puzzle. The likelihood of a participant finding the answer is proportional to the portion of the network's total mining capacity.

To set up a mining rig, you need either a GPU (graphics processing unit) or an application-specific integrated circuit (ASIC).

However, before you spend the time and equipment, read this summary to see if mining is really for you. We will concentrate mainly on Bitcoin (when referring to the network or the blockchain as a term, we will use "Bitcoin" throughout and "bitcoin" when referring to several individual tokens).

The key attraction for many mining companies is the possibility of Bitcoin being compensated. That said, you don't have to be a miner to own tokens for cryptocurrencies. You can also purchase cryptocurrencies using fiat currency; you can swap it with another crypto on an exchange like Bitstamp (as an example, using Ethereum or NEO to buy Bitcoin); you can even earn it by shopping, writing blog posts on sites that pay cryptocurrency users, or even setting up crypto accounts that make interest. Steemit, which is like intermediate, is an example of a crypto blog site, Except that users can pay bloggers by paying them in a proprietary cryptocurrency called STEEM. STEEM can then be exchanged for Bitcoin elsewhere.

The Bitcoin reward earned by miners is an opportunity that motivates individuals to assist with the primary objective of mining: legitimizing and monitoring Bitcoin transactions, ensuring their legitimacy. Since these duties are distributed across the world by many users, Bitcoin is a decentralized" cryptocurrency or one that does not depend on any central authority to regulate its control, such as a central bank or government.

How to mine bitcoins:

As auditors, miners get paid for their jobs. They do the job of checking the validity of transactions with Bitcoin. This convention is intended to keep honest Bitcoin users and was conceived by the founder of bitcoin, Satoshi Nakamoto. Miners are helping to avoid the double-spending problem' by checking transactions.

Double spending is a situation in which the same bitcoin is illicitly spent twice by a bitcoin owner. This isn't a concern with actual currency: if you send someone a $20 bill to buy a bottle of vodka, you don't have it anymore, so there's no danger of using the same $20 account to purchase next door lotto tickets. Although there is the possibility of making counterfeit money, it is not quite the same as spending the same dollar twice, literally. "there is indeed a risk that the user could make a copy of the virtual workforce and send it to a trader or another party thus retaining the original." there is a risk that the holder could make a copy of the digital token and send it while retaining the original to a merchant or another party.

Let's assume that you have a $20 bill of legitimacy and a $20 account of fake. If both the true and the fake bills were to be spent, anyone taking the time to see the serial numbers of both bills could see they were identical and that one of them was false. What a Bitcoin miner does is analogous—they track transactions to ensure users don't try to spend the same bitcoin twice illegitimately. This is not a great analogy – we're going to clarify it further.

Once miners have tested 1 MB (megabyte) of bitcoins, known as a "block," these miners can be paid a lot of bitcoins (more about the bitcoin reward below as well). The 1-MB limit was developed by Satoshi Nakamoto and is a controversial one. Some miners claim the block size should be increased so that additional information can indeed be processed and checked by the bitcoin network more quickly.

Note that checking one MB of transactions makes a coin miner qualify for bitcoin – not everyone who contains transactions gets paid.

Theoretically, 1MB of transactions may be as low as one or several thousand transactions (although not all common). It depends on how much transaction data was obtained.

So I could still not get bitcoin for this after all that effort in validating transactions?

That is right.

You have to satisfy two requirements to win bitcoins. One is an effort; one is an affair of pleasure.

  • You have to satisfy two requirements to win bitcoins. One is an effort; one is an affair of pleasure.
  • To get the right answer or closest answer to a number query, you have to be the first miner. It is also referred to as work proof.

What do you mean, "the correct number problem response?"

The good news: It does not require complicated math or computing. You may have learned miners solve thorny problems with mathematics, which is not strictly valid. The first miner to arrive with a 64-digit hexadecimal number (the "hash") is less than or equal to the target hash. It's guesswork, practically.

The bad news: It is guessing, but since each of these problems is on a trillion order in the total number of potential guesses, it's an unbelievably challenging task. Miners need a lot of computational power to solve a problem first. You have to have a high "hash rate" to successfully mine, as calculated in Megahash (MH/s), Gigahash/s (GH/s), and Terahaash (TH/s).

This is the best many hashes.

Mining and bitcoin circulation:

Besides lining miner's pockets and helping the bitcoin community, mining serves a further essential purpose: it is the only way to release new cryptocurrencies. In other words, the mining currency is fundamentally 'minting.' Apart from coins minted by Genesis blocks, which were created by founder Satoshi Nakamoto, each one of the Bitcoins has been made due to miners. As of Nov.2020, around 18,5 million bitcoins were in circulation.1 In the absence of miners, Bitcoin would still exist and be accessible as a network, but no new bitcoin would ever be available.

It is time before Bitcoin mining ends; according to the Bitcoin Protocol, the total amount of Bitcoins is restricted to 21 million2. But since bitcoin mining has decreased over time, it is not until the year 2140 that the final Bitcoin is circulated. This does not mean transactions are no longer checked. Miners continue to search and are charged fees for transactions so that the Bitcoin network's credibility stays in place.

Besides the short-term Bitcoin payout, you can be a coin miner to "voting" when you propose improvements to the Bitcoin network protocol. In other words, in making decisions on such matters as forking, miners have absolute control.

How much a miner earns:

Bitcoin mining benefits are reduced every four years by half. When Bitcoin was mined in 2009, you can make BTC 50 by mining one stone. This was facilitated by half to 25 BTC in 2012. This is again halved to 12.5 BTC by 2016. The reward also halved to 6.25 BTC on 11 May 2020. Bitcoin prices in November 2020 were approximately 17,900 dollars per Bitcoin, meaning you will gain 121,875 dollars (6.25 x 17,900) to complete a block.3 This could be no lousy motivation to solve this thoroughly complicated haunt.

You can search the Bitcoin Clock, which updates this information in real-time if you want to keep track of when these halves are happening. Interestingly, bitcoin's market price has been closely associated with the decline in new coins that have come into circulation over its history. This decline in inflation has increased the shortage, and with it, the price has traditionally risen.

If you are fascinated by how many blocks have been extracted up to now, there are many websites, including

What do I need to mine bitcoins?

While people may have fought for blocks with a regular machine at home early in Bitcoin's history, this is no longer the case. This is because Bitcoin's mining difficulty varies over time. The target of the Bitcoin network is to create one block every 10 minutes to make sure that the blockchain works appropriately and its ability to process and verify transactions.

However, if one million mining plants compete to solve the hash problem, they will probably find a solution faster than ten mining plants that deal with the same problem. Bitcoin is therefore intended for evaluation and adjustment of mining difficulties in all 2,016 blocks or approximately every two weeks. When Bitcoin's computer power is increased, the level of difficulty in mining increases to maintain block output at a constant pace.

The reduction in computing power means a decrease in difficulty. When Bitcoin launched in 2009, the initial difficulty level was one, to get a feeling of how much computational power is involved. It is over 13 trillion since November 2019.

All this means that to compete for mine, miners now need to invest in powerful computer equipment, such as GPU, or an application-specific integrated circuit, more realistically (ASIC). It can be between $500 and tens of thousands. Some miners – primarily the miners of Ethereum – are buying individual GPUs to cobble mining operations. As a cheap way.

The following photograph is a fortune-built home-made mine. These rectangular blocks with whirling fans are the graphics cards. Note the twist-type sandwich keeping the metal pole graphics cards. This probably isn't the best way to do it, and as you can imagine, many miners are there for both fun and money.

The "explain it like I am five" version:

It is difficult to grasp the ins and outs of bitcoin mining as it is. Consider an illustrative example of how the problem of hash works: I tell three of my friends that I have a number between one and 100, that I write on paper and put it in an envelope. I don't have to devise the exact number of friends; I have to be the first person to create any amount less or equal to what I am thinking. And the number of guesses they obtain is not limited.

I think of number 19, let's say. When Friend A conjectures 21, they lose 21>19. If Friend B deviates from 16 and Friend C deviates from 12, they have come to possible responses, both potentially with a 16<19 and 12<19 response. Friend B has no "extra credit" despite B's reply being closer to the goal reply of 19. Now imagine that I'm asking the question, "guess what number I'm thinking of, and I don't just ask three friends. I'm calling for a 64-digit hexadecimal number of millions of miners, and I'm dreaming about it. You now see that guessing the right answer is going to be incredibly difficult.

If B and C respond at the same time, the analogy of ELI5 disappears.

There are regular simultaneous responses concerning Bitcoin, but only one winning response will happen at the end of the day. If a multitude of simultaneous responses equal to or below the target number is given, a simple majority of the Bitcoin network — 51 percent — determines whether the miner will honor. In general, the miner does the most work or, in other words, the one who reviews the largest number of transactions. The block losing then transforms into an "orphan block." Orphan blocks are those not added to the blockchain. Miners who solve the hash problem successfully but did not validate most transactions are not reimbursed with Bitcoin.

What is a "64 digit hexadecimal number"?

Ok, here is a case in point:


The above figure has 64 numbers. Simple enough so far to grasp. This number does not consist only of numbers, but also letters in the alphabet, you probably noted. Why? Why?

Let's unpack the word "hexadecimal." to grasp what those letters do in the middle of numbers.

We use, as you know, the "decimal" method, i.e., base 10. In turn, this means that every digit of a multi-digit number has ten choices, from zero to nine.

On the other hand, hexadecimal means base 16 because hex comes from the Greek term six and "deca" from the Greek word 10. "Hexadecimal" means base 16. Each digit has 16 options in a hexadecimal method. However, our numeric system provides only ten ways to represent numbers (zero through nine). Therefore you must include letters a, b, c, d, e, and f in particular.

You need not determine the total value of the 64-digit number if you are mining Bitcoin (the hash). I say again the total hash value you don't have to calculate.

The relation between "64 hexadecimal number" with bitcoin mining:

Recall the analogy of ELI5, in which I wrote the No. 19 on paper and placed it on a screened envelope.

In the sense of bitcoin mining, this unknown amount is called the objective hash in the envelope.

What miners and hundreds of cooling fans do with those enormous computers are guessing on goal hash. Miners make this conjecture as quickly as possible by randomly generating as many "nonces" A nuance is short for "number only recycled once, and the nonce is the key that I keep talking about to produce these 64-bit hexadecimal numbers. Anancy is 32 bits in the size of Bitcoin mining, much less than the 256 bits hash. The first miner whose nonce produces a hash less than or equal to the goal hath earned credit for completing this block and is awarded BTC 6.25 spoils.

By progressing a 16-sided die 64 times to random numbers in theory, you might achieve the same goal, but what do you want on earth?

From, the following screenshot could help you bring together all of the details at a glance. Look at a list of all the activities of the mining of block #490163. The "winning" haze created was 731511405. The goal hash is indicated above. The word 'Antpool relay' refers to Antpool, one of the most popular mining pools, finished this particular block (more about mining pools below). As you can see, its involvement to the Bitcoin community is that 1768 transactions have been verified for this block. If all 1768 of these transactions for this block are really to be viewed, go to this page and scroll down to the "Transactions."

How to guess at the target hash?

Any goal hash begins with zero – up to 8 zeros and 63 zeros at minimum.

No minimum target is available, but the Bitcoin Protocol sets a maximum target. No goal could be higher than this:


Here are some examples of random hashes and the parameters for the miner's success:

How to maximize the chances of guessing the target hash before anyone else does?

You need to get a quick mining plant or enter a mining pool more realistically – a community of coin miners who combine their computing power and break mined Bitcoin. Mining pools are equivalent to Powerball clubs whose members purchase lottery tickets on a mass basis and plan to share their profits. In addition to individual miners, disproportionately large amounts of blocks are extracted through pools.

It is a number game, in other words, literally. You can't formulate or forecast the pattern based on previous target hashes. At the time of writing, the new block's complexity level is approximately 17,59 trillion, which means that a threat is less than the target of 17,59 trillion. No fair chance, even with a big powerful mining facility, if you are self-employed.

How to decide whether bitcoin will be profitable for you?

The cost of costly equipment required to solve a hah problem is not just a factor for miners. The significant quantity of power mining equipment used to process vast amounts of solvents must also be considered. Bitcoin mining, as it were, is essentially unprofitable for most miners. The Crypto compare website provides a helpful machine, which can be used to estimate the cost and the gain of numbers, including your hash speed and energy costs.

What is the coin mining pools?

Mining compensations are given to the miner who first finds an answer to the problem. A participant's chance of discovering the solution is proportional to the share of the network's cumulative mining capacity. A very little chance of finding the next block on their own for participants with a low percentage of the mining power. For, e.g., a mining card that could be bought for a few thousand dollars would sum to less than 0.001 out of 100 percent of the network's mining capacity.

It must have been a long time before the miner found a block with only a tiny chance of reaching the next block, and the difficulties that go up are much worse. The lender will never recover. Mining pools are the solution to this dilemma. Third-party mining pools and mineral coordination organizations are run. By working with all the participants in a collection and exchanging the payouts, miners will get a steady supply of bitcoin to start their miner's day. provides data on individual mining pools.

As described earlier, buying bitcoin on several exchanges is the most convenient way to buy it. During the 1849 California gold rush, the old view is that the intelligent investment was not to pit for gold but rather to turn into the pickaxes used for mining. It would help if you still exploited a pickax technique. The old view is focused on that. Or invest in firms which produce these pickaxes, to put it in a modern way. In a cryptocurrency sense, the equivalent of a pickax is a business manufacturing Bitcoin mining machinery. You may consider looking, for example, at companies that produce ASICs or GPUs.

Is bitcoin mining legal?

Bitcoin mining's legality is solely contingent upon the place. The Bitcoin principle could jeopardize the supremacy of fiat currencies and government oversight of financial markets. Bitcoin is also, in some areas, entirely unconstitutional.

In more countries than not, Bitcoin possession and mining is legal. Algeria, Egypt, Morocco, Bolivia, Ecuador, Nepal, and Pakistan are a few examples of countries where it is illegal. Bitcoin and mining, in general, are legal in most of the world.

Risk of mining:

Financial and regulatory threats are the risks of mining. As already mentioned, Bitcoin mining and mining are a financial danger in general. One must make all the attempts to buy mining equipment for hundreds of thousands of dollars to make no return on their investment. That said, access to mining pools would mitigate this risk. You can rethink if you are considering mining and living in an environment that is forbidden. Before investing in mining machinery, you should also look into your country's laws and general feelings regarding cryptocurrency.
