What Exactly is Bitcoin and How Does it Work? Complete Guide

Bitcoin has been the subject of many discussions since its inception, but what exactly is Bitcoin and how does it work?

This is a complete beginner’s guide to Bitcoin.

Join me let’s explore this topic if you want to understand Bitcoin and how it works. 

In truth, cryptocurrency has been a buzzword in recent years, and Bitcoin is often considered the poster child of this digital currency revolution. 

However, despite its popularity, many people are still unsure of what exactly Bitcoin is and how it works. 

There have also been many debates and controversies about Bitcoin since its inception.

But in this post, I am going to discuss what exactly Bitcoin is, its creation, how it works, and how to invest in it.

I will also cover other important topics around Bitcoin – to help you better understand this revolutionary technology that has gained increasing popularity over the years.

What Exactly is Bitcoin?

Bitcoin is a digital currency or cryptocurrency. 

It is a decentralized currency, which means it is not controlled by any government or financial institution. 

Instead, it operates on a peer-to-peer network where users can directly send and receive payments without intermediaries such as banks or payment processors.

The backbone of Bitcoin is the blockchain, which is a decentralized, public ledger that records all transactions made on the network. 

The blockchain ensures that all transactions are secure and transparent, as each transaction is verified by multiple nodes on the network before it is added to the ledger. 

This makes it difficult to alter or manipulate transaction data, ensuring the integrity of the system.

Bitcoin transactions are fast, secure, and low-cost. 

What Year was Bitcoin Started

The domain name Bitcoin.org was registered in August 2008.

In October of the same year, the now-famous white paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System,” was published on Bitcoin.org.

On January 3, 2009, the first Bitcoin block was mined. This is now known as the “genesis block”.

A week later, the first test transaction took place. 

Bitcoin had no real monetary value at this point. 

In fact, the first economic Bitcoin transaction happened more than a year later, on May 22, 2010. When a Florida man spent 10,000 Bitcoin for 2 Papa John’s pizzas. This day has been celebrated as Bitcoin Pizza Day ever since. 

What is the Main Purpose of Bitcoin

Bitcoin was created in the aftermath of the 2008 financial crisis, which highlighted many of the weaknesses and inefficiencies of traditional financial systems. 

Bitcoin was seen as a potential alternative to these systems, providing greater transparency, security, and control over one’s finances.

A currency to provide a way for people to make peer-to-peer transactions without the need for intermediaries such as banks or governments. 

Bitcoin was designed to be a trustless system not controlled by any person, group, government, or financial institution, and therefore free from manipulation or inflation.

Bitcoin is often compared to gold because of its scarcity. 

There is a finite amount of Bitcoin in circulation, with only 21 million ever to be mined. 

This scarcity is intended to make Bitcoin more valuable over time.

Who is the Real Creator of Bitcoin

Bitcoin was created by an unknown person or group using the pseudonym “Satoshi Nakamoto”. 

The true identity of the creator(s) remains a mystery, and they have not been publicly identified.

How is a New Bitcoin Created

New bitcoins are created through a process called “mining.” 

Bitcoin mining involves solving complex mathematical problems using specialized computer hardware to validate and verify transactions on the Bitcoin network.

When a miner successfully solves a problem, they are rewarded with a certain amount of bitcoins, which is currently 6.25 Bitcoin per block but is halved after every 210,000 blocks mined, or roughly every 4 years.

A block is a group of transactions that have been validated and added to the blockchain, which is a public ledger that records all Bitcoin transactions.

The mining process is designed to be resource-intensive and time-consuming to ensure that the creation of new Bitcoin is slow and steady. 

In fact, the total number of Bitcoin that can ever be created is limited to 21 million, which is expected to be reached in the year 2140.

It’s important to note that the mining process also plays a critical role in securing the Bitcoin network and ensuring that transactions are processed quickly and efficiently.

Mining Bitcoin is one of the many ways to earn Bitcoin for free

To get a better understanding, you can read:

Number of Satoshis in a Bitcoin

There are 100 million satoshis in 1 Bitcoin.

The term “satoshi” refers to the smallest unit of Bitcoin, named after Bitcoin’s unknown creator(s) Satoshi Nakamoto. 

It is similar to how there are 100 cents in 1 US dollar.

1 sat = 0.00000001 BTC

100,000,000 sat = 1 BTC

Number of Satoshis in a Bitcoin

This is why you don’t need to buy 1 Bitcoin to start investing in Bitcoin. 

In fact, you can start investing in Bitcoin with as little as $20.

Where to See Live Bitcoin Price

There are several websites and applications where you can see the price of Bitcoin. 

Two of the most popular options are:

These platforms provide the real-time price of Bitcoin and other cryptocurrencies, historical data, price charts, market capitalization, trading volume, and other relevant information about the cryptocurrency market.

How is Bitcoin different from Traditional Currency?

Bitcoin differs from the traditional currency in several ways. 

Firstly, it is decentralized, meaning is not controlled by any government or financial institution. 

Instead, it operates on a peer-to-peer network. 

Secondly, it is digital, meaning that it exists solely in digital form and does not have any physical equivalent like banknotes or coins. 

So ignore anyone who wants to sell physical Bitcoin to you. 

Thirdly, its transactions are recorded on a public ledger called the blockchain, which makes them transparent and difficult to alter. 

Finally, unlike fiat currencies, Bitcoin has a limited supply, with only 21 million units that can ever be created.

How Does Bitcoin work

Here are how Bitcoin works, including the technology behind it and the process of mining.

Blockchain technology

Bitcoin transactions are recorded on a public ledger called the blockchain. 

The blockchain is essentially a database that records all transactions that have ever occurred on the Bitcoin network. 

It is a decentralized system, meaning there is no central authority controlling it.

The blockchain is made up of a series of blocks, each containing a group of transactions. 

These blocks are linked together in chronological order, forming a chain.

Each block contains a unique code called a hash, which is generated by a mathematical algorithm that takes into account the data in the block. 

This hash links the block to the previous block in the chain, making the entire chain tamper-proof.


Mining is the process of adding new transactions to the blockchain. 

Miners use powerful computers to solve complex mathematical equations, which allows them to add new blocks to the chain. 

In exchange for their work, miners are rewarded with newly created Bitcoins.

Mining also serves as a way to verify transactions on the network. 

Miners check that transactions are valid before adding them to a new block, and the network as a whole verifies each block before adding it to the blockchain. 

This verification process ensures that all transactions on the network are legitimate.

Transactions and Wallets

Bitcoin transactions are sent from one digital wallet to another. 

Each wallet has a unique address, which serves as a destination for the transaction. 

Transactions are verified by the network, and once verified, they are added to the blockchain.

Digital wallets are software programs that store Bitcoin and allow users to send and receive it. 

They come in several forms, including desktop, mobile, and web-based wallets. 

Each wallet has a unique address that serves as the destination for Bitcoin transactions.

Why do people want Bitcoin?

Here are some reasons people like Bitcoin:

  • Potential for high returns: While the price of Bitcoin can be volatile, the truth remains it has seen incredible growth since its creation in 2009, which has led many investors to take notice. In 2010, one Bitcoin was worth less than $0.01, but as of March 2023, one Bitcoin is worth over $27,000. Bitcoin is the best-performing asset of the last decade – surpassing other investment options like stocks, bonds, gold, and silver.
  • Hedge against Inflation: People use Bitcoin as a hedge against inflation. As you may know, inflation can erode the value of traditional currencies, making them less valuable over time. Bitcoin on the other hand can help protect against inflation, as its value continues to increase over time due to limited supply and an increase in demand.
  • Fast Transfers and Low fees: The ability to transfer funds quickly and at lower transaction fees is another reason people like Bitcoin, particularly for international transactions. Unlike traditional transfers, Bitcoin transactions can be processed in a matter of minutes, making it an ideal option for investors who require quick transaction settlements.
  • Independence from a Central Authority: Bitcoin also offers investors independence from the central authority, which is one of the key advantages of this technology. The government cannot control or censor it, which can be important in countries with authoritarian governments.
  • Anonymity: Bitcoin transactions are relatively anonymous, which means users can make purchases without revealing their identity.

How do people get Bitcoin?

How long does a Bitcoin Transaction take

The time it takes for a recipient to receive a Bitcoin transaction can vary depending on several factors, such as network congestion, transaction fees, and the size of the transaction.

In general, Bitcoin transactions are added to a block approximately every 10 minutes. 

However, if the network is congested, it can take longer for a transaction to be included in a block.

To increase the likelihood of a transaction being confirmed quickly, users can attach a higher transaction fee to the transaction. 

Miners are incentivized to include transactions with higher fees because they earn fees for adding transactions to a block.

In general, a transaction with a reasonable fee can be confirmed within 10 minutes to an hour. 

Anything outside of that can be a result of a congested network and low transaction fees.

Some wallets and crypto exchanges may allow users to choose between different levels of fees when sending Bitcoin to ensure faster confirmation times.
