🪙 What Is Cryptocurrency?
Cryptocurrency is a digital asset designed to work as a medium of exchange using cryptography to secure transactions. Unlike traditional currencies issued by governments (like the Indian Rupee), cryptocurrencies are decentralized and typically operate on blockchain technology, which is a public ledger maintained by a network of computers.
Here’s how it works:
- 🔐 Security: Transactions are encrypted and verified by network participants (miners or validators).
- 📊 Transparency: Every transaction is recorded on a blockchain, making it traceable and tamper-resistant.
- 💸 Popular Types: Bitcoin (BTC), Ethereum (ETH), and stablecoins like USDT are among the most widely used.
Is Cryptocurrency Legal in India (2025)?
Yes, cryptocurrency trading is legal in India—but with important caveats:
| Aspect | Status in India (2025) |
|---|---|
| Legal Tender | ❌ Not recognized as legal tender (you can’t use it to buy groceries or pay bills) |
| Trading & Investing | ✅ Legal to buy, sell, and hold crypto assets like Bitcoin and Ethereum |
| Taxation | 💰 30% tax on profits + 1% TDS on transactions |
| Regulation | ⚖️ Exchanges must register with FIU-IND and follow KYC/AML norms |
| Future Framework | 🧾 COINS Act 2025 is in development to regulate crypto more clearly |
India’s stance is best described as “legal but not fully regulated.” You can trade and invest, but you must comply with tax laws and use registered platforms. The government is actively working on clearer rules, including investor protection and exchange licensing.
If you’re considering investing, it’s smart to:
- Use FIU-registered exchanges
- Keep records of all transactions
- Understand the risks (volatility, scams, cybersecurity)

How Blockchain Works (Simplified)
Blockchain is like a digital notebook that everyone can see but no one can erase. It’s the tech behind crypto.
🧩 Key Concepts:
- Block: A container of transactions.
- Chain: Each block links to the previous one using a cryptographic hash.
- Decentralized: No single authority; everyone on the network verifies transactions.
- Immutable: Once added, data can’t be changed.
⚙️ How a Transaction Happens:
-
- Initiation: You send crypto to someone.
- Broadcast: The transaction goes to the network.
- Validation: Miners/validators confirm it’s legit.
- Block Creation: Verified transactions are grouped into a block.
- Consensus: The network agrees on the block.
- Addition: The block is added to the chain.
- Completion: Transaction is finalized and visible to all.
- 🔐 Why It’s Secure:
- Every block has a unique hash.
- Changing one block means changing all others—nearly impossible.
- Uses cryptography and consensus algorithms like Proof of Work or Proof of Stake.
