Bitcoin   Cryptocurrency
crypto-currency, or crypto is a digital asset designed to work as a medium of exchange wherein individual coin ownership records are stored in a ledger existing in a form of a computerized database using strong cryptography to secure transaction records, to control the creation of additional coins, and to verify the transfer of coin ownership. It typically does not exist in physical form (like paper money) and is typically not issued by a central authority. Cryptocurrencies typically use decentralized control as opposed to centralized digital currency and central banking systems.
When a cryptocurrency is minted or created prior to issuance or issued by a single issuer, it is generally considered centralized. When implemented with decentralized control, each cryptocurrency works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database.
Bitcoin, first released as open-source software in 2009, is the first decentralized cryptocurrency. Since the release of bitcoin, other cryptocurrencies have been created

How Does Cryptocurrency Work?

Cryptocurrency uses blockchain technology. Blockchain data is secured through cryptography. Each participant has their own private key that is assigned to the transactions and it acts as a digital signature. If a record is altered, the digital signature will become invalid and the network will come to know that something has happened. Blockchain stores transaction information across vast networks of computers that continuously check and verify information with each other.
