What is cryptocurrency
Cryptocurrency is a digital or virtual currency that uses cryptography for security and operates independently of a central bank. It is a form of decentralized currency that is created and stored electronically.
Cryptocurrencies can be used to buy goods and services, and they can also be traded on various online platforms. They offer several advantages over traditional forms of currency, including faster and cheaper transactions, greater privacy and security, and greater accessibility for people who do not have access to traditional banking services.
However, cryptocurrencies also come with some risks, including high volatility, lack of regulation, and the potential for use in illegal activities such as money laundering and fraud.

How does cryptocurrency work
Cryptocurrencies work through a decentralized computer system that uses cryptography to secure transactions and control the creation of new currencies. The main process works like this:
- Cryptocurrency transactions are initiated by sending a request from a digital wallet to the blockchain network.
- Transactions are verified and confirmed by a network of computers (called nodes) on the blockchain network.
- Once a transaction has been verified, it is recorded on a public ledger known as the blockchain.
- In the case of some cryptocurrencies, such as bitcoin, new units of currency are created through a process called mining.
- Cryptocurrencies are secured using a combination of cryptographic techniques and consensus mechanisms.
Generally, cryptocurrencies work through a decentralized computer system and cryptographic methods that ensure the security and integrity of transactions and the creation of new currencies.
