🧠 Why Does Money Have Value?
Government Authority
Governments say it's official
Bank Management
Banks help manage it
Collective Agreement
Everyone agrees to use it
A paper note costs almost nothing to make, but it can buy food, toys, or houses because we all agree it can. Money is basically a shared story we all believe in.
🪙 Bitcoin vs Traditional Money
💵 Traditional Money
- Controlled by governments and central banks
- Printed or created by banks
- Banks decide who can send money and when
- Can be frozen, blocked, or delayed
₿ Bitcoin
- Not controlled by any government
- Created by computer code
- Anyone can use it with the internet
- Runs 24/7, everywhere
Bitcoin is money without a boss. That's why people say Bitcoin is decentralized.
💻 What Is Cryptocurrency?
Cryptocurrency is digital money. It doesn't exist as coins or notes. It exists as numbers stored on computers across the world.
Buy Things Online
Send Money Globally
Save or Invest
The most famous cryptocurrency is Bitcoin, but there are many others like Ethereum, Litecoin, and Ripple.
⚙️ What Is Blockchain?
Cryptocurrency uses a technology called blockchain. Think of blockchain like:
📘 A giant digital notebook
🌍 Shared by computers all over the world
✍️ Every transaction is written down
🔒 Once written, it's almost impossible to change
Instead of one bank keeping records, thousands of computers check each other's work. That's why blockchain is secure, transparent, and hard to cheat.
⛏️ Crypto Mining – Explained Simply
So… where does Bitcoin come from? This is called mining, but no one is digging holes.
Solve Hard Puzzles
Computers solve very difficult mathematical puzzles
Check Transactions
Verify and validate new transactions
Add to Blockchain
Record verified transactions in the blockchain
Get Rewarded
New Bitcoin is created as a reward
Mining is how new coins are made, the system stays honest, and no one cheats. Mining uses a lot of energy because the puzzles are intentionally hard.
🔐 Wallets, Keys, and Digital Safety
To use crypto, you need a wallet.
1
Get a Wallet
Doesn't hold physical money, holds access to your crypto
2
Receive Private Key
Like a secret password or key to a digital safe
3
Keep It Safe
If you lose it, no one can help you
⚠️ Important: Crypto gives freedom, but also responsibility. No bank can reset your password!
