What is Bitcoin?
Bitcoin is the largest and first cryptocurrency in Blockchain technology. Satoshi Nakamoto introduced the concept of Blockchain and Bitcoin together, and this cryptocurrency, i.e., Bitcoin, was created in 2009. Bitcoin has some features added to Blockchain as a Digital Currency. Since Bitcoin is based on a Blockchain system, let’s understand it with a small example.
If you transfer a Bitcoin to someone, you will send Bitcoin using the receiver’s public “key” and the sender’s private “key”. It is like a message where the public “key” of the recipient acts as a phone number or email, and your private “key” serves as a signature, ensuring only you can send this message.
Bitcoin for Beginners should understand that one of the most valuable functions of Bitcoin is its secure transaction system. It uses a powerful combination of a private key, a public key, and a timestamp to ensure that each transaction is safe and verifiable. Bitcoin is digital money that works without banks, allowing users to send funds instantly to anyone, anywhere in the world, at any time, without needing approval or relying on banking hours.
Why Bitcoin Was Invented
Bitcoin was created as an alternative to conventional banking services. The 2008 financial crisis revealed issues with centralised financial systems, bank failures, governments printing large amounts of money, and the erosion of public trust. Bitcoin provides a solution: a monetary system governed by mathematics, not politicians.
How Bitcoin Works (Simplified)
- No central authority: No bank or government controls Bitcoin.
- Limited supply: Only 21 million Bitcoins will ever exist (like digital gold).
- Digital wallets: Bitcoins are stored in a secure app or device.
- Peer-to-peer: Transactions take place directly between users, without intermediaries.
- 💡Real-world comparison: Sending Bitcoin is like sending an email; you don’t need a bank, just an internet connection.
Bitcoin vs. Traditional Money
Aspect | Bitcoin | Traditional Bank Money |
Control | You have full control of your funds | Banks can freeze or restrict access to your account |
Money Supply | Limited to 21 million coins (cannot be inflated) | Unlimited supply governments can print more money |
Transaction Speed | Fast: 10 minutes to 1 hour globally | Slow: 1–5 business days for international transfers |
Fees | Low: Usually between $1 and $5 | High: $15 to $50+ for wire or cross-border transfers |
Availability | Always available 24/7 access from anywhere | Limited, depending on banking hours and country borders |
The Importance of Bitcoin
Financial Freedom

- Send money anywhere in the world without permission.
- Avoid high fees from banks and money transfer services.
Inflation Protection
- The US dollar has lost more than 90% of its value since 1971 due to money printing.
- The fixed supply of Bitcoin (21 million) makes it inflation-resistant.
- People in Argentina, Turkey, and Nigeria use Bitcoin to protect their savings.
Censorship Resistance
- Governments can block payments (such as PayPal freezing donations). Bitcoin transactions cannot be stopped.
