Introduction to Cryptocurrency
A cryptocurrency (also called crypto asset, digital token, or cyber currency) is an electronic currency issued peer-to-peer without requiring banks or central intermediaries. These digital assets operate on decentralized computer networks using blockchain technology combined with cryptographic protocols for transaction verification.
