Cryptocurrency is digital money that exists on a decentralized network called a blockchain. It uses cryptography to secure transactions and allows people to send and receive value without banks.
Unlike the rupee or dollar, no central bank issues it, no single server stores it, and no government can freeze it unilaterally. It runs on a shared public ledger called a blockchain, maintained simultaneously by thousands of computers around the world.
- Cryptocurrency is digital money secured by cryptography and recorded on a decentralised network called a blockchain.
- No bank or government controls it; transactions are verified by a global network of computers.
- Bitcoin is the first and largest cryptocurrency; thousands of others exist, each with different purposes.
The term “cryptocurrency” combines “cryptography” (the math that secures data) and “currency” (a medium of exchange). Since Bitcoin launched in 2009, the category has grown to over 10,000 tokens by some estimates, spanning payments, smart contract platforms, gaming tokens, and more.
How Cryptocurrency Works
Every cryptocurrency transaction goes through three steps.
- Broadcast: When you send crypto to someone, your wallet broadcasts the transaction to a peer-to-peer network of nodes (computers running the blockchain software).
- Validation: Nodes check that you actually own the coins you are sending and that you have not already spent them. This double-spend check is the core innovation of blockchain.
- Recording: Validated transactions are bundled into a “block” and added to the chain. Once recorded, the entry is practically impossible to alter because changing one block would require rewriting every block after it across thousands of machines simultaneously.
The result is a transparent, tamper-resistant record that anyone can audit without needing a trusted third party like a bank.

What is a Blockchain?
Main Guide: What is blockchain
A blockchain is the underlying technology that makes cryptocurrency possible. Think of it as a Google Sheet that thousands of people can read, that only adds rows (never edits or deletes), and that is copied identically across every participant’s computer.
Each “block” in the chain contains:
- A batch of recent transactions
- A timestamp
- A cryptographic hash of the previous block (this is what “chains” them)
Because each block references the one before it, altering old data would invalidate every subsequent block. The cost of rewriting history on a large, decentralised blockchain like Bitcoin is astronomically high, making the ledger trustworthy without a central authority.
Types of Cryptocurrency
Not all cryptocurrencies serve the same purpose. Broad categories include:
- Payment coins. Bitcoin (BTC) was designed as peer-to-peer electronic cash. Litecoin, Bitcoin Cash, and Ripple (XRP) are also primarily used for value transfer.
- Smart contract platforms. Ethereum (ETH) lets developers build applications on top of the blockchain. Solana, Avalanche, and BNB Chain are similar.
- Stablecoins. Tokens like USDT and USDC are pegged 1:1 to the US dollar, providing price stability while retaining the speed of crypto transfers.
- Altcoins: Any cryptocurrency other than Bitcoin is technically an altcoin. This is a broad category covering thousands of projects.
- DeFi tokens: Protocols for decentralised finance issue governance tokens that let holders vote on protocol changes.

Why Do Cryptocurrencies Have Value?
This is one of the most common questions from new investors. Cryptocurrencies derive value from several overlapping factors.
- Scarcity: Bitcoin has a hard cap of 21 million coins. Scarcity, when combined with demand, creates price pressure similar to gold.
- Utility: Ethereum has value partly because you need ETH to pay transaction fees on the Ethereum network. The more apps that use Ethereum, the more ETH is needed.
- Network effects: The larger the user base, the more useful and valuable a network becomes, reinforcing adoption.
- Speculation: Honestly, a significant portion of crypto pricing at any given moment reflects speculative demand. Prices can move 20-50% in days, which creates both opportunity and serious risk.

Cryptocurrency in India: What You Need to Know
Crypto is legal to buy, sell, and hold in India. However, the government taxes crypto gains at 30% (plus applicable cess), and there is a 1% TDS on transactions above a threshold. Losses from one crypto asset cannot be offset against gains from another.
You can buy crypto safely in India through an FIU-IND compliant crypto exchange with KYC and AML requirements. WazirX operates with full KYC and allows INR deposits and withdrawals via UPI and bank transfer.
Key Risks to Understand Before You Buy
Cryptocurrency is not a savings account. Before investing, be aware of the following:
- Price volatility: Crypto can lose 50-80% of its value in a bear market. Do not invest money you need in the short term.
- Counterparty risk: Holding crypto on an exchange means trusting that exchange. Keep only trading funds on exchanges; consider a hardware wallet for long-term holdings.
- Scam risk: Rug pulls, phishing attacks, and fake projects are common. Research every project before buying.
- Irreversibility: Crypto transactions are final. Sending to the wrong address typically means permanent loss.
