What is Cryptocurrency?
क्रिप्टोकरेंसीCryptocurrency is a digital or virtual currency secured by cryptography that operates on decentralized blockchain networks, independent of central banks.
Full Explanation
A cryptocurrency is a form of digital money that uses cryptographic techniques to secure transactions and control the creation of new units. Unlike traditional currencies issued by governments (fiat), cryptocurrencies operate on decentralized networks (typically blockchains) where transactions are verified by network participants rather than a central authority. Bitcoin, created in 2009, was the first cryptocurrency. As of 2026, there are thousands of cryptocurrencies with a combined market cap exceeding $2 trillion.
Example
Bitcoin (BTC) and Ethereum (ETH) are the two largest cryptocurrencies by market cap. In India, you can buy crypto on a registered exchange using UPI.
