#CryptoSecurity101 Cryptocurrency, often called "crypto," is a digital or virtual form of money that uses cryptography for security. Unlike traditional currencies, cryptocurrencies operate on decentralized networks, usually blockchain technology, making them secure and transparent. Bitcoin, the first and most famous crypto, was created in 2009. Cryptos are not controlled by governments or banks, offering peer-to-peer transactions without intermediaries. They can be used for payments, investment, and as a store of value. While offering great potential, cryptos are also known for volatility and regulatory uncertainties. As technology and adoption evolve, cryptocurrencies continue to reshape finance and economic systems worldwide.
