Bitcoin Mining- A Bird’s Eye View

A brief overview of Mining
  • Bitcoin mining is the procedure towards verifying, securing and storing Bitcoin transactions. Moreover, there is much more to be considered regarding this. In any case, before getting into what is Bitcoin mining and how it functions, let us discuss a few important things about Bitcoin.
  • When a payment is made using a credit card, the credit card company checks and records the exchange, presently, when the payment is made using a Bitcoin, there are no central or intermediaries like the credit card company to check the transaction. Instead, it is verified by Bitcoin miners.
  • In contrast to traditional cash like USD, JPY, EUR, etc. which is printed by banks, Bitcoin cannot be printed by anybody. With traditional money, the bank can print a lot of cash as they need; there is no extreme limit on it. Bitcoin, however, has the most extreme limit of 21 million. This implies there must be 21 million Bitcoins which has been produced.

The Fundamental necessities for Bitcoin mining are:

  • Special personal computers
  • A solid Internet connection
  • Power
Block and the Blockchain Technology

Many Bitcoin exchanges occur at the same time. The transactions that occur at the same time are divided into groups, which are called Blocks. Bitcoin miners need to verify these groups or blocks, where they check the exchanges in groups rather than verifying them separately. When a block is confirmed, it gets added to a chain of blocks that have just been validated. This is the technical reason behind Bitcoin being known as the blockchain.


A proof of work is a bit of information which is costly, time-consuming to deliver to fulfill specific requirements. It must be meaningless to check whether the data meets the said prerequisites. Creating proof-of-work can be a random procedure with lower possibilities, so a great deal of experimentation is required by and large before a valid proof of work is produced. Bitcoin implements the Hash cash proof-of-work.

Reasons for Mining
  • Bitcoin works uniquely in contrast to conventional currencies. Where dollars and pounds are managed by banks and financial foundations where they confirm when exchanges happen, Bitcoin works based on a public ledger framework. If the transactions are to be approved to avoid the same Bitcoin from being spent twice, various Bitcoin nodes, operated by miners around the globe, need to give their seal of approval.
  • Moreover, Mining is an unsafe procedure. It not only takes the difficult work from the mining chips themselves, but loads and loads of power, Powerful cooling, and a reliable system connection. The reward toward the end is not ensured either, so it should never be taken lightly.
How Mining functions
  • The reason why it is considered mining is that it does not involve a physical demonstration of digging. Bitcoin is entirely advanced tokens that do not require panning streams or explosive excavation. However, they do have their exploring and recovery, which is where the “mining” terminology originates from.
  • Planned Miners download and run customized mining software, of which there are a few popular options, and frequently join a group of different miners doing the same. However, together or alone, the software complies late Bitcoin exchanges into blocks and demonstrates their validity by computing a “proof of work,” that covers the majority of the information in those blocks. That includes the mining hardware taking a vast number of hypotheses at a specific integer again and again until they locate the right one.
  • It is an algorithmically extraordinary procedure that is additionally checked by intentional increments in difficulty as an ever-increasing number of miners attempt to make the next block in the chain. This is the reason why individuals join the group, and they use the most powerful application ASIC (Application specific integrated circuit) mining hardware which is successful at mining Bitcoins today.
  • The individual miners or groups who are the first to make the proof-of-work for a block are rewarded with exchange charges for those confirmed exchanges and an allowance of Bitcoin. The compensation is comprised of new Bitcoin which are created through the process of mining. This will keep on occurring until each of the 21 million has been mined.
  • There is no guarantee that any miner or mining group will create the right integer expected to confirm a block and to acquire the reward. That is precisely why miners join groups. Even though their reward is far smaller, they should mine the following block since it is shared among all the individuals in the group, the odds of acquiring such a reward are far more noteworthy as a group, and an ROI (Return on Investment) on any venture is significantly more likely.
Bitcoin Mining Hardware
  • The initial step to begin Bitcoin mining is to buy the mining equipment. Choosing the correct equipment is vital for the success of mining. As Bitcoin turned out to be increasingly popular, the miners began to use all the more dominant computers. They utilized faster GPU (Graphics Processing Units) that could solve the issues quicker, which means they would win and be rewarded with the new Bitcoin.
  • If you are wondering about what happened when Bitcoin turned out to be increasingly popular, Miners got significantly faster. Rather than utilizing CPUs and GPUs, they began using special Bitcoin mining equipment called ASIC (Application Specific Integrated Circuits). Moreover, if you want to lead and mine Bitcoin, you will need an ASIC. ASIC that are made for mining are exceptionally powerful and fast. They focus only on mining.
Bitcoin Wallet

When you are ready with your Bitcoin mining equipment, downloaded the software and joined a mining group, you can begin mining Bitcoins. In any case, if you are to be rewarded in Bitcoins, have you considered where the Bitcoins will be stored? Unlike conventional cash, Bitcoin cannot be stored in a bank account. Instead, it is stored in a Bitcoin wallet.

There are three kinds of Bitcoin wallets:

  • Web wallets
  • Software wallets
  • Hardware wallets.
Bitcoin Mining Reward
  • Currently, Bitcoins miners are rewarded with 12.5 Bitcoins per block.
  • However, this number halves every four years. In this way by 2020, the reward will be reduced to 6.25 Bitcoin per block.
  • Currently, it is 12.5 Bitcoins per block. In this way, the time taken to mine one Bitcoin is 10 minutes. That implies one Bitcoin is mined at 48 seconds.
How demanding is Bitcoin Mining?
  • Satoshi Nakamoto, who created Bitcoin, drafted the standards for mining such that the additional mining power the system has; the harder it is to figure the response to the mining math problem. So the trouble of the mining procedure is self-adjusting to the collected mining power the system has.
  • With more Bitcoin miners joining the system, the mining level of difficulty increases. This implies the miners or mining groups with all the more dominant hardware will necessarily win. This points out to the need to purchase costly hardware.
The cost of Bitcoin Mining

The two fundamental costs Bitcoin mining incur:

Hardware & computer cost: For beginners, the expense of Bitcoin mining hardware will be $600-$1000, and it is considerably more costly if you need to purchase the best hardware accessible.

  • Power cost: Bitcoin mining consumes lots and lots of electricity. The expense of power at your area can have a tremendous effect on the payment of Bitcoin mining. If the power in your general vicinity is excessively costly, you may lose cash by mining Bitcoins instead of making profits.
Future of Mining
  • Bitcoin was initially intended to enable anybody to take part in the mining procedure with a home PC and enjoy the process of mining themselves, accepting a reward now and again for their service. ASIC miners have made it impossible for anybody to invest a large number of dollars and use cheap and ample power. That is the reason cloud mining has turned out to be so popular.
  • Even though the hardware has driven many miners out of the training; however, there are safeguards set up that prevents all remaining Bitcoins from being mined in a brief timeframe.
  • Every 2,016 blocks, at a rate of six blocks an hour, generally every two weeks, the mining difficulty is recalculated. For the most part, it increases as more miners and mining hardware join the system, yet if the general mining power were to lessen, the difficulty would diminish to keep up a 10-minute block generation time.
  • The reason behind that moderately hard 10 minute time is the way the number of Bitcoins being produced by the procedure will be gradual and generally controlled. That is aggravated by the decrease in remuneration for blocks mined every 210,000 blocks. Each time that limit is achieved, the reward gets split. At the end of 2018, the mining block reward was at 12.5 Bitcoins, which is worth around $80,000.
  • Later on, as mining rewards decline, the exchange remunerated to miners will make up a more significant percentage of Miner pay. The rate with which Bitcoin mining difficulty is expanding, mining hardware advancement is progressing at greater heights, and rewards are diminishing, projections for the last Bitcoins being mined limit into the 22nd century.
How do Miners earn Bitcoin?
  • To start with, for Bitcoin miners to earn Bitcoin from confirming exchanges, two things need to happen. Firstly, they should prove 1 megabyte (MB) worth of transactions, which can hypothetically be as small as one exchange yet are all the more often a few thousand, depending upon how much information every exchange stores, which is the simple part.
  • Second, to add a block of exchanges to the blockchain, miners must take care of a complex computational math problem, also called as proof-of-work. What they are doing is attempting to come up with a 64-digit hexadecimal number, called a “hash,” that is not exactly or equivalent to the target hash. Mainly, a miners PC releases hashes at a rate of Mega hashes every second (MH/s), Giga hashes every second (GH/s), or even Tera hashes every second (TH/s) depending upon the unit, speculating all conceivable 64-digit numbers until they arrive at an answer. It is a bet.
Why do Miners Mine?

That brings us finally, to the topic of why miners mine. The answer is straightforward; miners mine because the writer of a new block in the blockchain has authorization from the protocol to give themselves a reward of fresh new Bitcoins. The reward began at 50 Bitcoins per block. For every four years, the protocol is balanced, lessening the reward considerably. One day the reward will be extremely little; however, miners can likewise be remunerated by collecting expenses volunteered by clients that request exchanges.

Wrap Up


Eventually, one can make loads of cash by mining Bitcoin, but it relies upon many things, which are way out of control like power costs, the cost of Bitcoin, etc. It can give you a significant profit; however, it may not give you significant benefits. If the power costs are low, you can be optimistic about mining Bitcoin. If they are high, you are most likely cynical about mining Bitcoin; however, you can either follow that, or you should be ready to move to other countries!

Quick tips, notes, Interesting facts
  • Currently, there are more than 17,225,338 Bitcoins that have been mined and the reward for mining one full block is set at 12.50 of Bitcoins.
  • Just 21 million Bitcoin can be mined flat; when each of the 21 million Bitcoins will be mined, no new Bitcoins can be made. By this, we can know what Bitcoin mining is.
  • The thing about Bitcoin is that it works without intermediaries like banks or credit card organizations.
  • Bitcoin miners are paid with new Bitcoin. This is a unique way that new Bitcoin can be made.
  • When Bitcoin mining began in 2009, you could mine using basic PCs like the ones we purchase from retail stores. That PC’s CPU (Central Processing Unit) had enough power capacity to take care of the mathematical issue.
