Cryptocurrency, also known as crypto, is a digital or virtual currency that uses cryptography to secure transactions and to control the creation of new units. It is designed to work as a medium of exchange through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it. Cryptocurrencies are stored in digital wallets and are recorded in a public ledger.
Some key features of cryptocurrency include:
-
Decentralization: Cryptocurrencies are decentralized, meaning they are not controlled by any central authority.
-
Security: Cryptocurrencies use encryption to verify transactions and to provide security and safety.
-
Peer-to-peer system: Cryptocurrency is a peer-to-peer system that can enable anyone anywhere to send and receive payments.
-
Altcoins: Tokens, cryptocurrencies, and other digital assets other than Bitcoin are collectively known as alternative cryptocurrencies, typically shortened to "altcoins" or "alt coins".
The first cryptocurrency introduced was Bitcoin, which is the most commonly traded one. Ethereum is the second most valuable cryptocurrency and can be used for complex transactions. Other more common cryptocurrencies, called altcoins, include Cardano, Solana, Dogecoin, and XRP.
Cryptocurrencies are increasingly popular alternatives for online payments, but there are risks involved in using them. To use cryptocurrencies, you need a cryptocurrency wallet, which can be software that is a cloud-based service or is stored on your computer or mobile device.
