Bitcoin has captured attention across the globe, sparking interest from financial analysts, tech lovers, and everyday folks alike. Whether you are deep into investing or just starting to explore the crypto space, getting a grasp on Bitcoin is more relevant than ever.
Here’s a breakdown of the key things to know from where it all began, to how mining works, how transactions happen, and everything in between.
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.
Cryptocurrency is a digital currency in which transactions are verified and records maintained by a decentralized system using cryptography, rather than by a centralized authority.
Unlike traditional money, Bitcoin exists solely in the digital world, with transactions secured by cryptography.
- Decentralization: Banks or governments do not control Bitcoin transactions. 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. Users conduct all transactions in the virtual world, record them in a ledger called the Blockchain, and share it among themselves. 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: You authenticate transactions using a private key (your unique signature) and send them to a public key (the recipient’s address).
- Blockchain Recording: Once the system verifies the transaction, it adds it to the blockchain, ensuring no one can alter it.
For instance, if you want to buy a laptop using Bitcoin, the seller provides their public key. You initiate the payment using your private key, and the system records the transaction on the blockchain.
Bitcoin Transactions Explained
- Basically, to use Bitcoin, you need to own some, you can buy it from others using physical currency, or mine it yourself 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 solves the puzzle earns 25 Bitcoin as a reward. Miners generate new Bitcoins, but only after the ledger adds 99 more blocks.
- 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 actively mine Bitcoin as part of 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 receive Bitcoin as a reward for their efforts.
Key Points About Bitcoin Mining:
- Reward System: Miners receive Bitcoin as a reward for solving puzzles. Initially, the system rewarded miners with 50 BTC, but it halves this amount approximately every four years (currently the system rewards 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, miners have mined over 19 million Bitcoins.

Why Is Bitcoin So Valuable?
Scarcity, utility, and demand drive Bitcoin’s value. 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 the shop owner receives using his own private key. Once the transaction completes, 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, people perform transactions using a Digital Wallet or Bitcoin wallet, and the transactions shown above are automated and done in a very user-friendly way.
- Explanation of the Change:
- “transactions are done by using Digital Wallet or bitcoin wallet” changed to “people perform transactions using a Digital Wallet or Bitcoin wallet”: This explicitly states who is performing the action (“people”) and makes “perform” the active verb.
- The rest of the sentence was already in a relatively active structure, although we could make a minor adjustment for even more directness:
- “the above-shown transactions are automated and done in a very user-friendly way” changed to “the system automates and executes the above-shown transactions in a very user-friendly way”: This version explicitly states the actor (“the system”) responsible for the automation and execution.
- Combining these changes gives the revised sentence:
- In the real world, people perform transactions using a Digital Wallet or Bitcoin wallet, and the system automates and executes the above-shown transactions 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.

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.”
- This is the prime reason some countries have not officially accepted Bitcoin and its transactions as a currency or money.
- While some countries have accepted it as currency and they do not prohibit transactions. They even allow buying or selling through.
