What is Bitcoin?

Bitcoin (BTC) is a digital currency created in 2009 by an unknown person or group using the pseudonym Satoshi Nakamoto. It is a decentralized form of currency, meaning that it does not rely on any central authority such as banks or governments to issue and manage its transactions.

Transactions are verified by network nodes through cryptography and recorded in a publicly distributed ledger called the blockchain. This ledger is maintained by a network of users who use their computers to validate and process transactions. Because the blockchain is decentralized and distributed, it’s very difficult to alter or tamper with the information it contains.

Bitcoin can be used to purchase goods and services online, send money internationally, or even store value for long-term investment purposes. As it has no physical form, bitcoin can also be traded between users without having to go through traditional banking systems or payment processors like PayPal or Visa/Mastercard networks.

With its increasing popularity among investors worldwide due to its low transaction fees compared with other forms of payment methods such as credit cards, bitcoin is becoming an increasingly attractive option for those looking for alternative ways of making payments online.

Bitcoin is decentralized

Unlike traditional currencies, which are controlled by central banks and governments, Bitcoin is decentralized. This means that it operates independently of any central authority, and is maintained by a network of users around the world.

Bitcoin is digital

Bitcoin is a purely digital currency, which means that it exists entirely in digital form. You can’t hold it in your hand like physical currency, but you can buy and sell it just like any other asset.

Bitcoin transactions are secure

Transactions on the Bitcoin network are secured by a complex cryptographic algorithm, which makes them very difficult to hack or tamper with.

Bitcoin is finite

There will only ever be 21 million bitcoins in circulation. This limit is built into the Bitcoin protocol and cannot be changed.

Bitcoin is divisible

Each bitcoin can be divided into smaller units, called satoshis. There are 100 million satoshis in one bitcoin.

Bitcoin is volatile

Bitcoin’s value can fluctuate wildly over short periods of time, making it a risky investment for some people.

Bitcoin is not anonymous

While Bitcoin transactions are not tied to your real-world identity, they are recorded on a public ledger that is visible to anyone. It is possible for someone to trace transactions back to you if they have the right tools and information.

History of Bitcoin

Bitcoin is the first and most well-known cryptocurrency, created by an unknown individual or group of individuals using the pseudonym Satoshi Nakamoto. The original white paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System” was published in 2008, proposing a system for electronic transactions without relying on trust. On January 3, 2009, the first block of the Bitcoin blockchain, known as the Genesis block or Block 0, was mined by Satoshi Nakamoto.

How Bitcoin works?

Bitcoin works by using a decentralized network of computers to validate and process transactions. Here’s a simplified explanation of how it works:

Create a wallet to send/receive Bitcoin

You have to create a Bitcoin wallet first and generate a public/private key pair. Then you can share your public key with others to receive Bitcoin. You receive Bitcoin from the Bitcoin network.

Bitcoin transactions are broadcast to the network

When you send or receive Bitcoin, your transaction is broadcast to the network of computers running the Bitcoin software.

Transactions are validated by miners

Miners are users who use specialized hardware to validate and process transactions on the Bitcoin network. They do this by solving complex mathematical problems that verify the transactions and add them to the blockchain.

Transactions are added to the blockchain

The blockchain is a public ledger that contains a record of all Bitcoin transactions. Once a transaction has been validated by miners, it is added to the blockchain and becomes a permanent part of the network.

Transactions require a digital signature

Each Bitcoin transaction requires a digital signature to prove that it was created by the owner of the Bitcoin. This helps to prevent fraud and ensure that transactions are secure.

Recent Developments

As of June 2023, Bitcoin and other major cryptocurrencies were affected by regulatory actions from the U.S. Securities and Exchange Commission (SEC), which sued Binance and Coinbase, two of the world’s largest crypto exchanges. These events led to a decrease in the Bitcoin price and rumors of an “alliance” to destroy crypto. Moreover, trading apps like Robinhood and eToro announced the removal of support for certain cryptocurrencies, contributing to market instability.

Bitcoin Use Cases

Recent developments have shown explosive growth in Bitcoin use cases during the first quarter of 2023. These include:

  • Bitcoin Non-Fungible Tokens (NFTs): The launch of the Ordinals’ protocol in January 2023 enabled the creation of unique “digital artifacts” that can be held and transferred across the Bitcoin network, leading to over a million inscriptions being minted.

  • Bitcoin Name Services (BNS): There was a 400% surge in BNS registrations on the BTC.us platform since 2022. This platform allows users to register human-readable “.btc” domain names that can be used to host a site or send and receive Bitcoin.

  • Bitcoin Smart Contract Platform: Stacks blockchain, a Bitcoin smart contract platform, introduced a new digital asset called “Stacks Bitcoin” (sBTC) to make Bitcoin fully programmable. They launched an sBTC testnet and are targeting a mainnet launch later in 2023.

Pros & Cons


  • Protection Against Inflation: A ceiling is set on the circulation of Bitcoin, offering some protection against inflation.

  • Freedom of Payment: Bitcoin can be used regardless of borders between countries and continents, contributing to ease of use. Transaction costs are also typically lower than with traditional currencies.

  • Security: The security and completeness of information required for transactions are guaranteed through blockchain technology. Wallets are encrypted, and regular backups can be performed. No data relating to users’ purchasing behavior is collected.


  • Unstable Value: Bitcoin’s value can be quite unstable due to its uncommon usage as a payment method and the influence of small events, activities, and transactions. A decrease in investors can also cause a decline in Bitcoin’s value.

  • Risk of Loss: If you lose the private key of your Bitcoin wallet, it’s not possible to restore it, potentially leading to a complete loss of your funds.

  • Risk of Deflation: As the number of Bitcoins available decreases, their price rises, and speculation on the part of investors increases. This can potentially lead to deflation.

  • Regulatory Challenges: At a legal level, there are difficulties because there are countries that do not allow unconditional use of Bitcoin. In 2023, the European Union approved the Markets in the crypto-axis, the first regulation in the sector.

How to get Bitcoin?

Buy Bitcoin on an exchange

The most common way to acquire Bitcoin is to buy it on a cryptocurrency exchange. Some popular exchanges include Coinbase, Binance, Kraken, and Gemini. You can buy Bitcoin using a credit or debit card, bank transfer, or other payment methods supported by the exchange.

Receive Bitcoin as payment

If you are a business owner, you can accept Bitcoin as payment for goods or services. You can set up a Bitcoin wallet and provide your customers with a Bitcoin address to send payments to.

Mine Bitcoin

Bitcoin Mining is the process by which new Bitcoins are created and transactions are verified on the network. However, mining Bitcoin requires specialized hardware and software and is no longer profitable for most individuals.

Receive Bitcoin as a gift

You can also receive Bitcoin as a gift from someone who already owns it. They can transfer Bitcoin to your wallet address just like sending an email or a text message.

It’s important to note that Bitcoin prices can be volatile, so it’s important to research and understand the risks before investing in it. Additionally, you should always store your Bitcoin in a secure wallet to protect it from theft or hacking.

How does Bitcoin mining work?

As shared earlier, Bitcoins are created by a process called Mining which is performed by mining nodes. A mining node, also known as a miner, is a computer that performs the complex mathematical calculations required to validate and process transactions on the Bitcoin network. Here’s how it works:

Mining nodes validate transactions

When a new transaction is broadcast to the Bitcoin network, mining nodes validate the transaction to ensure that it’s valid and not a fraudulent transaction.

Mining nodes compete to solve a mathematical puzzle

Once a group of transactions has been validated, the mining nodes compete to solve a complex mathematical puzzle. This is known as the Proof of Work (PoW) algorithm.

The first node to solve the puzzle adds the block to the blockchain

The mining node that solves the puzzle first is rewarded with newly minted Bitcoins and transaction fees. Once a block has been added to the blockchain, the transaction is considered complete.

The difficulty of the puzzle is adjusted every 2016 blocks

In order to maintain a consistent rate of block creation, the difficulty of the puzzle is adjusted every 2016 blocks. If more mining nodes join the network, the difficulty is increased to ensure that the average time between blocks remains at around 10 minutes.

Mining requires specialized hardware

Bitcoin mining requires specialized hardware, called Application-Specific Integrated Circuits (ASICs), which are designed specifically for mining Bitcoin. These ASICs are extremely powerful and consume a lot of electricity.

Mining pools allow for more consistent earnings

Because mining Bitcoin requires so much computational power, it’s very difficult for individuals to earn Bitcoin by mining alone. Mining pools allow groups of miners to work together and share the rewards.

Bitcoin mining is a crucial part of the Bitcoin network, as it ensures the security and integrity of transactions. However, mining is becoming increasingly difficult and expensive, and it’s no longer profitable for most individuals to mine Bitcoin on their own.

How can I mine Bitcoin?

Mining Bitcoin requires specialized hardware and software, as well as a significant amount of electricity. Here are the basic steps to mine Bitcoin:

Get the right hardware

Bitcoin mining requires specialized hardware called ASICs (Application-Specific Integrated Circuits). You will need to purchase an ASIC miner that is specifically designed for mining Bitcoin.

Choose a mining pool

As mining Bitcoin is very difficult and competitive, it’s often more profitable to join a mining pool, where you work together with other miners to solve blocks and share the rewards. Choose a reputable mining pool that has a good track record and a reasonable fee structure.

Download mining software

You’ll need to download mining software that’s compatible with your ASIC miner. The software will allow you to connect to the mining pool and start mining Bitcoin.

Configure your miner

Once you have your hardware, software, and mining pool, you’ll need to configure your miner by entering the necessary information, such as the mining pool URL, username, and password.

Start mining

Once your miner is configured, you can start mining Bitcoin. The mining software will automatically connect your miner to the mining pool and start processing transactions and solving blocks.
