Bitcoin has become a buzzword globally, captivating financial experts, tech enthusiasts, and everyday individuals alike. Whether you’re a seasoned investor or a curious observer, understanding Bitcoin is essential in today’s digital age.
Let’s delve into everything you need to know about Bitcoin, its origins, mining process, transactions, and more.
The Rise of Bitcoin and Its Creator: Satoshi Nakamoto
In October 2008, an individual (or group) under the pseudonym Satoshi Nakamoto published a groundbreaking white paper titled Bitcoin: A Peer-to-Peer Electronic Cash System.
This paper outlined the concept of a decentralized digital currency, free from government or financial institution control.
But who exactly is Satoshi Nakamoto?
Despite various claims and speculations, Nakamoto’s identity remains a mystery.
Some believe it’s a pseudonym to protect their privacy, while others suggest it could be a collective effort.
What Is Bitcoin?
Bitcoin is the first and most popular cryptocurrency, a form of digital currency that operates on blockchain technology.
Unlike traditional money, Bitcoin exists solely in the digital world, with transactions secured by cryptography.
- Decentralization: Bitcoin transactions are not controlled by banks or governments. It is a form of cryptocurrency which relies on blockchain technology. By means of cryptocurrency or crypto (short form of cryptocurrency), it is a digital currency or digital money that uses cryptography to secure its currency transactions.
- Blockchain: A public ledger records all Bitcoin transactions, ensuring transparency. As it is a digital currency there is no physical transaction and you will not find any physical coin of it. All transactions are in the virtual world, all transactions are recorded in a ledger called Blockchain and this is shared among all the users. It is just data.
- Limited Supply: There will only ever be 21 million Bitcoins, adding to its scarcity and value. Thus it is a full-proof system in terms of digital transactions.
How Does Bitcoin Work?
Bitcoin transactions occur in the digital realm. Here’s how it works:
- Digital Wallets: To use Bitcoin, both the sender and receiver must have digital wallets.
- Public and Private Keys: Transactions are authenticated using a private key (your unique signature) and sent to a public key (recipient’s address).
- Blockchain Recording: Once verified, the transaction is added to the blockchain, ensuring it cannot be altered.
For instance, if you want to buy a laptop using Bitcoin, the seller provides their public key. You initiate the payment through your private key, and the transaction is recorded on the blockchain.
Bitcoin Transactions Explained
- Basically, to use a Bitcoin, you need Bitcoin; which can be purchased from others using physical currency, or even you can mine Bitcoin by solving a mathematical puzzle.
- Now to earn Bitcoin some people do Bitcoin mining! .What happens that every ten minutes or so mining computers collect a few hundred pending bitcoin transactions (a “block”) and turn them into a mathematical puzzle? The miner who found the solution gets 25 Bitcoin as a reward and thus they are generated (but only after another 99 blocks have been added to the ledger).
- Thus by solving mathematical puzzles you can earn Bitcoin but it is not easy. As sometimes the expense on computers (it can be a computer network) and electric power is much higher than the market value of earned Bitcoin. Still, some people are heavily involved in mining which is also known as the bitcoin network.
- There are so many websites and companies that help your mining activity by charging you some fees just like banks.
Bitcoin Mining: How New Bitcoins Are Created
It is a process where powerful computers (or networks) solve complex mathematical puzzles to validate transactions and add them to the blockchain. Miners are rewarded with Bitcoin for their efforts.
Key Points About Bitcoin Mining:
- Reward System: Miners receive Bitcoin as a reward for solving puzzles. Initially, the reward was 50 BTC but is halved approximately every four years (currently 6.25 BTC per block).
- High Costs: Mining requires expensive hardware and consumes significant electricity, which can sometimes outweigh the value of the Bitcoin earned.
- Bitcoin Supply Cap: Only 21 million Bitcoins will ever exist. As of now, over 19 million Bitcoins have been mined.
Why Is Bitcoin So Valuable?
Bitcoin’s value is driven by scarcity, utility, and demand. With only 21 million Bitcoins in existence, its limited supply contributes to its high price. In January 2025, Bitcoin reached an all-time high of nearly $106,963 USD per Bitcoin.
Factors Influencing Bitcoin’s Value:
- Scarcity: Finite supply of 21 million Bitcoins.
- Adoption: Increasing acceptance by individuals, companies, and even governments.
- Security: Blockchain ensures secure and tamper-proof transactions.
- Inflation Hedge: Bitcoin acts as a store of value, similar to gold.
How to sell or buy using BitCoin
- Now let us take an example that you need to buy a Laptop and Shop owner accepts Bitcoin. Now to pay Shop owner you first need to know his public key (digital alphanumeric number).
- Then using your private key you initiate a transaction which in turn gets received by the Shop owner by using his own private key. Once the transaction gets completed you get your laptop.
- Now let me explain this in a very easy way. You want to send some Bitcoin to me. Then we both should have a public key or address and a very personal private key to authenticate transactions. Now to send using your private key you initiate a transaction to me by my public key. At the other end, I will use my private key to receive Bitcoin.
- In the real world, transactions are done by using Digital Wallet or bitcoin wallet and the above-shown transactions are automated and done in a very user-friendly way. Moreover you will find an app for bitcoin in App store or Play store.
How to Buy or Sell Using Bitcoin
Buying or selling using Bitcoin is straightforward once you have a digital wallet. Here’s a simple step-by-step process:
- Get a Digital Wallet: Download a Bitcoin wallet from the App Store or Play Store.
- Buy Bitcoin: Purchase Bitcoin from cryptocurrency exchanges using your local currency.
- Initiate Transactions: Use your private key to send Bitcoin to someone’s public key.
Examples of Bitcoin Usage:
- Buying goods and services online or in physical stores.
- Sending money across borders without hefty fees.
- Investing in Bitcoin as a long-term asset.

- Energy Consumption: Mining requires immense energy, raising environmental concerns.
- Complexity: Understanding Bitcoin and blockchain technology can be challenging for beginners.
Countries and Bitcoin: Who Accepts It?
Bitcoin’s legal status varies across the globe.
- Countries That Accept Bitcoin:
- El Salvador (official currency)
- Japan
- Switzerland
- Germany
- Countries That Restrict Bitcoin:
- China
- Egypt
- Bangladesh
Why Some Countries Ban Bitcoin
Bitcoin’s anonymity can facilitate illicit activities such as money laundering and tax evasion. This has led some governments to impose restrictions or outright bans.
Why Bitcoins and Why not.
“Each and every transaction is secured and private. That means you don’t have to pay taxes or fees to the Government or Bank.”
