#USCryptoWeek Cryptocurrency, or crypto, is a digital form of money that uses cryptography for secure transactions. Unlike traditional currencies issued by governments, cryptocurrencies are decentralized and run on blockchain technology, a public digital ledger that records all transactions. Bitcoin, the first and most popular crypto, was created in 2009. Other well-known examples include Ethereum, Binance Coin, and Solana. Crypto allows peer-to-peer transactions without the need for banks or intermediaries. People use it for investment, payments, and decentralized finance (DeFi). Its value is highly volatile, influenced by supply, demand, market trends, and technological developments. Crypto is transforming the future of money and finance.
