What is Cryptocurrency?
Cryptocurrency is a type of digital or virtual currency that uses cryptography for security. Unlike traditional currencies issued by governments (fiat money), cryptocurrencies operate on decentralized networks using blockchain technology.
Key Features of Cryptocurrency:
- Decentralized: No central authority, such as banks or governments, controls cryptocurrencies.
- Secure & Transparent: Transactions are recorded on a public ledger (blockchain), making them transparent and secure.
- Limited Supply: Most cryptocurrencies have a fixed supply, reducing inflation risks (e.g., Bitcoin has a cap of 21 million coins).
- Fast & Low-Cost Transactions: Compared to traditional banking systems, crypto transactions are often faster and cheaper.
How Does Cryptocurrency Work?
Cryptocurrencies operate using blockchain technology, which is a distributed ledger system. Each transaction is verified by a network of computers (nodes) and recorded in blocks.
The Basic Process of a Cryptocurrency Transaction:
- User Initiates a Transaction: A sender uses their digital wallet to transfer cryptocurrency to another user.
- Transaction Verification: Network nodes verify the transaction using consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS).
- Transaction Added to Blockchain: Once verified, the transaction is permanently recorded on the blockchain.
- Funds Received: The recipient gets the cryptocurrency in their digital wallet.
This decentralized process ensures security, transparency, and immutability of transactions.

Risks and Challenges of Cryptocurrency
Despite the advantages, cryptocurrencies also come with risks:
❌ Volatility
Crypto prices can fluctuate significantly within short periods, leading to potential losses for investors.
❌ Regulatory Uncertainty
Some governments have imposed restrictions on crypto usage, leading to uncertainty in the market.
