Cryptocurrency is a type of digital or virtual currency that exists only online and uses cryptography to secure transactions. Unlike traditional money (like INR, USD, or EUR), cryptocurrencies are not controlled by any central authority such as a government or bank. Instead, they operate on a decentralized technology called blockchain.
In simple words, cryptocurrency is internet money that allows people to send and receive payments securely without involving banks or intermediaries.
There are around 20,000 different types of cryptocurrencies. The most well-known and first cryptocurrency is Bitcoin which was developed in 2009.
Other popular cryptocurrencies include Ethereum (ETH), Binance (BNB), Bitcoin Cash, Ripples (XRP) etc. Each of these currencies serves a different purpose with some optimized for use in place of cash, and others designed for private, direct transactions.
Since cryptocurrencies are digital and paperless, the coin or bill you own doesn’t actually exist.
As an alternative, owners store their bitcoin in a digital wallet and trade it on an online exchange or cryptocurrency exchange. Your wallet may be online or stored offline on a hardware device similar to a USB drive.
Some popular exchanges offer an in-app wallet. Cryptocurrencies are maintained and valued by their users.
Decentralization is a basic tenet of cryptocurrency. Whereas most currencies are backed by a central bank, the U.S. dollar, for example, is backed by the “full faith and credit” of the U.S. government.
How Does Cryptocurrency Work?
Cryptocurrencies work on a blockchain, which is a public digital ledger that records all transactions. Here’s how it functions:
- A user initiates a transaction (sending crypto to someone).
- The transaction is verified by a network of computers (called nodes).
- Once verified, the transaction is added to a block.
- The block is permanently stored on the blockchain.
- The transaction cannot be altered or deleted.
This process ensures transparency, security, and trust.
Where are The Transactions Recorded?
Transactions involving cryptocurrencies are kept on a decentralized ledger. We refer to this ledger as a blockchain. The blockchain, a public database of the transactions is accessible to other cryptocurrency holders and records every purchase or sale of cryptocurrency.
What is The Validation Process?
What is Cryptocurrency is open to everyone, but cryptography is used to protect the data on specific transactions — and the people involved with them — are secured using cryptography (the basis for the term cryptocurrency).
A digital validation procedure is used to validate each transaction before it is added to the Blockchain in order to avoid fraud.
Key Features of Cryptocurrency

3. Transparency
All transactions are recorded on a public ledger that anyone can view.

Is Crypto Trading Similar to Any Other?
Cryptocurrencies do share characteristics of commodities like gold — they can be bought and sold for cash.
Crypto and Stocks appear to be more closely linked— increased trading volume share of crypto institutions versus retail has contributed to the high correlation between bitcoin and equities.
