Cryptocurrencies operate on decentralized networks, meaning they are not controlled by a single entity like a government or financial institution.
Transactions involving cryptocurrencies are recorded on a public ledger called a blockchain, which allows for transparency and security.
There are now thousands of different cryptocurrencies available, with varying levels of popularity, market value, and use cases.
Cryptocurrencies can be bought and sold on digital currency exchanges, which operate similarly to stock exchanges.
While cryptocurrencies are often used for speculative investments, they can also be used for online purchases, remittances, and other transactions.
