Bitcoin is the first digital currency that was iroduced to the world and started a revolution in the economy and financial affairs of the world. When Bitcoin started its work, no one could have imagined what changes this innovation would cause. Many predicted the early death of Bitcoin over the years, but what happened was that the king of digital currencies was here to stay.
In this article, we have tried to explain Bitcoin education in simple and concise language. If you are also curious about the king of digital currencies and wa to know what features Bitcoin has, how it is stored and who corols it, watch the video below and stay with us uil the end of this article to get answers to your questions.
What is Bitcoin?
Bitcoin (Bitcoin) with symbol BTC and symbol ₿ or ฿ is a completely digital currency which is Deceralized in bed Blockchain Bitcoin exists. Issuance, transfer and all Bitcoin transactions are done and recorded in a deceralized manner on the same blockchain. Bitcoin blockchain such as ledger The bank works, but it is deceralized and transpare, and anyone can have a copy of it.
In fact, Bitcoin is a type of electronic money that does not involve an iermediary institution in its distribution, transfer and manageme, and its corol is in the hands of the people. With its emergence, Bitcoin fulfilled the long-standing dream of a completely digital money and put the world on the verge of a financial revolution. Today, this digital currency has become so popular that everyone is talking about it and was to know what Bitcoin is.
In this monetary system, people are their own banks and transfer money to each other directly without the need for a bank or ceralized institution. Suppose you wa to send money to a friend in another coury. If you wa to do this with traditional methods and through the banking system, what troubles and costs await you? Now imagine that there is a system through which you can make this transfer directly without the need of any bank or iermediary at any mome of the day and night; Welcome to the world of Bitcoin.
Bitcoin in the simplest language
The simplest and at the same time the most comprehensive definition that can be given for the question “What is Bitcoin” preseed, perhaps the title is the same article that “Satoshi Nakamoto” published in 2008 to iroduce Bitcoin: Peer-to-peer electronic money system.
According to this definition, first, Bitcoin is money; It means that it has the same function as money that we all know and deal with every day and every hour. Second, this is electronic money; That is, it does not have a physical state; Rather, it is completely digital and its transmission also happens on a digital platform. Third, Bitcoin is peer-to-peer; This means that there is no middleman or ceral institution like a bank in Bitcoin; Rather, its transmission is carried out directly from one person to another.
Bitcoin; A global network
Bitcoin is a network of computers and servers around the world that are connected to each other via the Iernet and run the Bitcoin core software. These computers, which are called nodes, have no superiority over each other and only store the Bitcoin database, which is called the blockchain. Anyone anywhere in the world can be a part of this network by running this software on any computer.

All people can transfer bitcoins to each other through the main software (Bitcoin Core) or Bitcoin wallet. This transfer (transaction) is received by nodes and recorded on the blockchain. Once a transaction is recorded on the blockchain, all nodes save it and no one can change or target this transaction.
The easiest way to understand what Bitcoin is is to compare it to the Iernet of Money. The Iernet is completely digital, no one owns or corols it, it is completely borderless, it is available 24 hours a day, 7 days a week, and everyone can easily send data to each other through it.
What are the features of Bitcoin?
We said that Bitcoin is functionally just like the money we know well. In this sense, Bitcoin is a tool for transferring value and an iermediary for the exchange of goods and services; But the nature of Bitcoin has serious differences with common money that we call fiat currency. In order to better understand what Bitcoin is and to understand its nature, we will examine its main features.
Deceralized
The term deceralized means that something is widely distributed and does not have a single, ceralized place or institution. The technology and infrastructure that governs the production, supply and security of Bitcoin is not depende on a ceralized institution such as ceral banks or governmes.
The Bitcoin network is completely public and anyone anywhere in the world with just a computer and an iernet connection can connect to it and have a copy of it.
The manageme and administration of the Bitcoin network is also deceralized and at the disposal of network participas. Bitcoin is open-source and anyone can see its source code. Needless to say, the changes that are needed for the better administration of Bitcoin are approved and implemeed by voting among the participas.
Limited supply
One of the importa features of Bitcoin is its limited supply. Bitcoin is programmed in such a way that eveually only 21 million units will be released; That is, after the release of this number of bitcoins, no new bitcoins will be produced.
This limitation goes back to Satoshi Nakamoto’s most importa concern, which was the indiscriminate priing of money by governmes. Ceral banks pri new money without regulation whenever the governme was it, and this issue reduces the value of money; The same thing we call “inflation”. This is despite the fact that no one can produce as many Bitcoins as they wa.

Unfakeable
The Bitcoin or Blockchain database is like an accouing ledger that anyone can have a copy of; For this reason, it is also called distributed ledger (DLT). Now imagine that hundreds of thousands or even millions of people each have a copy of this ledger and every time a new transaction is registered in the network, they all update their copy.
By using this technology, Bitcoin has eliminated the possibility of any forgery and arbitrary changes in this ledger. In fact, if someone was to falsify a transaction or make a change in the ledger, they must apply it to all other copies as well; It is practically impossible.
Easy to carry
Bitcoin is on the blockchain network, and your access key to it is an encrypted phrase called a “private key” that works like a bank accou password. You can store this phrase in a software wallet on your mobile or laptop or in a hardware wallet similar to flash memory. You can even write it on a piece of paper and keep it in your pocket. Even easier, you can even save your own private key.
With this possibility, wherever you go in the world and even leave the planet, you just need to have an iernet connection; Because your bitcoins are in your hand; You don’t need a bank, no sending password by SMS, no autheication, no access to ierbank transfer or SWIFT system and the like. You can easily carry anywhere from a few dollars to billions of bitcoins with you or transfer them to someone else with a small fee.

Semi-anonymous transactions
The main elemes of every transaction in Bitcoin are: the sender and receiver and the amou of Bitcoin transferred. In Bitcoin transactions, the only thing that is recorded from the sender and receiver is their wallet address, and information that indicates the ideity of the sender or receiver is not recorded in the Bitcoin ledger; Hence, Bitcoin transactions are neither completely anonymous nor completely traceable.
Each transferred bitcoin can be traced back to its first transaction, and at the same time, it is impossible to know who exactly played a role in these transfers; For this reason, Bitcoin transactions are described as “semi-anonymous”.
Irreversible transactions
If you remember, we said that no specific person or eity runs Bitcoin; Rather, a network of computers around the world do this. Therefore, in the Bitcoin network, once a transaction is recorded, no one can cancel or reverse it. Even if someone sends bitcoins to the wrong address, they still have to put their money back; Unless the other party (receiver) does this in a new transaction.
Irreversibility was created in Bitcoin with the aim of eliminating the possibility of cheating and spending again; It means that no one can spend one bitcoin twice.
The creator of Bitcoin is anonymous
Bitcoin was created by an unknown ideity with the pseudonym “Satoshi Nakamoto”. No one knows who Nakamoto is or whether he was an individual or a group. There have been many speculations about Nakamoto’s ideity; But none of these hypotheses have been proven and the ideity of the creator of Bitcoin has always remained a mystery.

Where does bitcoin come from?
Bitcoin’s life cycle begins with a process called mining. Miners are the ones who secure the Bitcoin network and record transactions in the blockchain. Transactions are recorded in formats called “blocks” and eered io the blockchain or Bitcoin database. Whenever a miner succeeds in extracting a block, some new bitcoins are created and the system transfers it to the miner as a reward. This is where new bitcoins are born.
Bitcoin mining reward will reach zero in 2140; This means that no new bitcoins will be created after that.
Birth of Bitcoin with mining rewards
The block mining reward was initially 50 bitcoins; But according to Bitcoin rules, this amou is halved every four years. The process of halving the block mining reward is called halving. Currely, the reward per block is 6.25 bitcoins; It means that 3 halving eves have happened so far. It is ieresting to know that a new block is produced approximately every 10 minutes. The rules of Bitcoin are set in such a way that the duration of block mining always remains within this range.
What is the Bitcoin supply cap?
If uil now you had a question about the mechanism by which the supply of Bitcoin is limited, now you should have got your answer. If you look at the Bitcoin halving model with a mathematical perspective, you will see that eveually, after several years, the Bitcoin reward will practically reach zero. Calculations show that this will happen in 2140.

Where is Bitcoin stored?
You may have heard that Bitcoin is stored in your wallet; But this is not the reality. Bitcoin is not stored anywhere; Rather, it is these transactions that are recorded in the network and on the blockchain. Your balance is derived from the sum of your transaction output, also known as Unspe Transaction Output or UTXO.
Perhaps this issue can be explained better by meioning an example. Suppose you have a bitcoin address and Ehsan transfers 50 bitcoins to your address. At this poi you have 50 unspe bitcoins. Then, you transfer 10 bitcoins to the dynamic address and Mahsa transfers 5 bitcoins to your address. The unspe output of the dynamic transaction is 40 bitcoins (50 minus 10) and the unspe output of the Mahsa transfer is 5 bitcoins. Now your balance is equal to 40 plus 5 bitcoins, that is 45 bitcoins.

How to receive and send bitcoins?
Everyone on the Bitcoin network is one “public key” (Public Key) and one “private key” (Private Key) The public key works like the accou number and the private key works like the password to access the accou. Bitcoin transfer is done in such a way that the sender sends a certain amou of Bitcoin, which is not more than his balance, to the recipie’s address or his public key and signs this transfer with his private key.
Read more: private key; Everything you need to know about private keys
Once the transaction is signed, it is se to the Bitcoin nodes. Nodes check the validity of this transaction in terms of balance amou and private key validity. If everything was correct, the transaction gets the initial confirmation and eers the new block. When a new block is mined, the transaction within that block is eered io the Bitcoin blockchain or ledger. This transaction is now valid; But as more blocks are added to the blockchain after this transaction, the validity of that transaction increases.
Who made Bitcoin?
As we said, an anonymous ideity created Bitcoin. The activities of this ideity are registered on the iernet with the username and email of “Satoshi Nakamoto”. Nakamoto started developing Bitcoin in 2007. During this time, he was in coact with a number of cryptographers.
Nakamoto registered the bitcoin.org domain in 2008 and launched a website with this address. In the same year, he published an article iroducing Bitcoin, which is known as the Bitcoin White Paper.

The first version of the Bitcoin software was released on January 9, 2009 on the Sourceforge website (sourceforge.net). Nakamoto mined the first block of the Bitcoin blockchain on January 3, 2009, and other people have since coributed to the network.
The disappearance of the creator of Bitcoin
By mid-2010, Satoshi Nakamoto was involved in the developme of Bitcoin and made several modifications to it. Then, corol the Bitcoin to programming called Gwen Anderson (Gavin Andresen) and ended his participation. In April 2011, Nakamoto posted a message saying that he was busy with other work and erusted the bitcoins to the right person. This was the last known message from Nakamoto and he has not been heard from since.
Nick Sabo Nick Szabo Dorian Preice Satoshi Nakamoto (Dorian Preice Satoshi Nakamoto), Hal Finney (Hal Finney) and Craig Wright (Craig Wright) are among the famous people attributed to Satoshi Nakamoto; But either they themselves rejected this issue or it was rejected in court.
Who corols Bitcoin?
Bitcoin has no ceral eity. In fact, it is a network of computers around the world that all run the Bitcoin software and have a version of the blockchain.
Some computers only hold a copy of the blockchain, and others also mine Bitcoin.
All decisions related to the rules and capabilities and code of the Bitcoin software are made by the community of miners. Everyone can submit their proposed changes to Bitcoin in the form of specific standards. If these proposals attract enough support, they will be voted on by miners and, if approved, will be implemeed in Bitcoin.
Can Bitcoin be hacked?
Theoretically, it is possible to hack Bitcoin; But this requires such huge capital and powerful computers that it makes hacking Bitcoin practically impossible or unprofitable. Also, there may be flaws in the Bitcoin code that someone could exploit to damage the network or generate Bitcoin for themselves; But because Bitcoin is deceralized and open source, with thousands of developers working on it, the possibility of this happening is practically zero.
What is the method of obtaining bitcoins?
Bitcoin can be obtained in differe ways. Mining is the main way to earn bitcoins where you ieract directly with the bitcoin network itself. At the same time, you can buy bitcoins or get bitcoins in exchange for selling something. Next, we will examine these methods.
What is bitcoin mining?
The Bitcoin mining method is a process in which people give the computing power of their computer or mining device (ASIC), i.e. CPU capacity, to the network and receive rewards from the network in return. The method of mining Bitcoin is that the miner connects his device to the Bitcoin network. The job of this device is to find the number that the Bitcoin network has determined for a block. Any miner who finds this number first will get the block reward.
See: What is Bitcoin mining?
Thousands or even millions of computers and devices are connected to the Bitcoin network, and someone with the most computing power is most likely to win the race. Some users combine their computing power to increase their luck; That is, they form a collection called mining pool.
Thousands of devices connected to the mining pool together form a mining unit and have much more luck. When this pool succeeds in mining a block, it distributes its reward among all its members in proportion to their computing power.
Some who have access to a lot of capital or have been able to attract capital, create a mining farm to produce a lot of computing power. A mining farm is actually a collection of thousands of powerful mining machines.
Trading with Bitcoin
One of the easiest ways to earn Bitcoin is to accept it as a payme method. For example, if you wa to sell a product, sell it for Bitcoin; That is, give the product to the customer and the customer will pay bitcoins for it.
Buy Bitcoin
In addition to the meioned methods, you can buy Bitcoin with common currencies such as Rials, Dollars, or Euros. At first, Bitcoin was traded in forums and chat rooms; But today, there are many exchanges around the world that have made it possible to trade Bitcoin to dollars and digital currencies.
In these exchanges, you can transfer money directly from your bank card to the exchange accou and buy bitcoins in exchange. Only do this in reputable exchanges. Also, after buying Bitcoin, transfer it to your wallet and do not leave it in the exchange accou. Remember, the best place to store bitcoins is your wallet.
Can you buy anything with Bitcoin?
Currely, thousands of online and physical stores accept Bitcoin as a payme method and offer their services and goods in exchange for Bitcoin. People can make their purchases from these stores with Bitcoin.
One of the problems of this path was related to Bitcoin transaction fees, which became problematic for small purchases. The transfer fee in Bitcoin is such that it sometimes exceeds the price of the goods themselves. This problem was solved with the launch of the Lightning Network, and now even the smallest paymes are possible with Bitcoin.

How to buy bitcoin?
The best way to buy bitcoins is to visit digital currency exchange websites. Iranian users can buy bitcoins from exchanges using one of the following two methods:
To buy and sell bitcoins in reliable Iranian exchanges, you can use the new function of digital currency and find the best exchange rate of bitcoins.
- Buying Tether or other stablecoin from Iranian websites and converting it to Bitcoin in foreign exchanges such as KuCoin
To buy bitcoin in Iran, you can search for the term “buy bitcoin” in Google to find those Iranian exchanges that sell bitcoin with Rials and bank cards. After registering on these websites, you can directly buy bitcoins with your bank card.
Sometimes, users may prefer to use the second method due to the low liquidity of domestic exchanges or the high cost. In this case, users can buy Tether or other stablecoins from domestic websites and then convert it to Bitcoins at foreign exchanges such as Kocoin. For selling, you can choose the best price of Bitcoin in the selling queue and sell it to that accou.
What are Bitcoin wallets?
Digital currency wallets are generally divided io two types of hardware and software. All types of hardware wallets are the most secure; Especially if you are dealing with a large amou of bitcoins. There are differe types of software wallets; Including mobile, desktop and web.
Next, we will iroduce the best bitcoin wallets that you can choose according to your needs.

Frequely asked questions
At the end of the article, we answer some common questions related to Bitcoin.
Bitcoin is produced in the mining process and eers the market cycle. By participating in the Bitcoin network, miners ensure its security and produce new blocks. Every miner who succeeds in producing a block receives a reward from the network in the form of bitcoins, and this is the mome when new bitcoins are born.
Bitcoin can be bought from cryptocurrency exchanges. Many exchanges around the world sell bitcoins for common currencies. You can buy bitcoins from Iranian or foreign digital currency exchanges with a bank card or with currencies like Tether.
Bitcoin does not have a legally defined position in Iran; However, Article 2 of the General Penal Law states: “Nothing can be considered a crime; Unless punishme or preveive or educational measures have been determined for it according to the law. Therefore, buying and selling and keeping bitcoins is not a crime. However, Bitcoin mining has coury restrictions that you should research before doing so.
The profitability of Bitcoin mining depends on many factors, including the cost of electricity, the price of the mining machine, and the price of Bitcoin in the market. Those who wa to mine Bitcoin should consider these pois. To calculate Bitcoin profitability, you can use Mining calculator Use digital currency.
When all 21 million Bitcoin units are mined, the only source of income for miners will be from transaction fees. At that time, the amou of fees and the price of Bitcoin in the market will determine whether it is profitable to operate as a miner or not.
