Cryptocurrencies are digital assets that use cryptography and blockchain technology to enable secure online transactions. Unlike traditional currencies, cryptocurrencies are typically decentralized, meaning they are not controlled by a central bank or government.
They can be used for online payments, transferring funds, and in some cases as a store of value.

How Do Cryptocurrencies Work?
Most cryptocurrencies operate on a blockchain, which is a distributed ledger that records transactions across a network of computers.
When a transaction is made:
- The transaction is broadcast to the network.
- Network participants verify the transaction.
- The transaction is added to the blockchain.
- The blockchain is updated across all participating nodes.
This process helps ensure transparency and makes transaction records difficult to alter.
