#TrumpBTCTreasury Cryptocurrency is a digital or virtual currency secured by cryptography, operating on decentralized blockchain technology. Bitcoin, the first crypto, was launched in 2009, followed by thousands of alternatives like Ethereum, Solana, and Ripple. Crypto enables peer-to-peer transactions without intermediaries, offering transparency, security, and lower fees. It’s used for investments, payments, DeFi (decentralized finance), and NFTs. However, its volatility, regulatory uncertainty, and risks like scams and hacking remain concerns. Some countries embrace it, while others ban or restrict it. Despite challenges, crypto continues evolving, with institutional adoption and blockchain innovations shaping the future of finance and digital ownership.
