What Is Cryptocurrency | Mamamimi Me

Cryptocurrency is a digital or virtual currency that uses cryptography for security and is decentralized, meaning it is not controlled by any government or financial institution. It was first introduced with the launch of Bitcoin in 2009, and since then, various cryptocurrencies have been created, including Ethereum and Litecoin. Cryptocurrencies use a digital ledger to store individual coin ownership records, and the two most common consensus mechanisms are proof of work and proof of stake.
