Cryptocurrency is a decentralized form of digital or virtual currency that relies on cryptography for security and operates on a technology called blockchain. Introduced with Bitcoin in 2009, cryptocurrencies aim to provide a secure, transparent, and borderless means of financial transactions. Unlike traditional currencies, cryptocurrencies are not controlled by any central authority, such as a government or financial institution.
They utilize blockchain technology to ensure the integrity and immutability of transaction records. Popular cryptocurrencies include Ethereum, Ripple, and Litecoin. The growing interest in cryptocurrencies has led to debates about their potential impact on traditional financial systems and their role in the future of finance.
