#MetaplanetBTCPurchase Cryptocurrency, or crypto, is a digital form of money that uses blockchain technology to operate securely and transparently. Unlike traditional currencies issued by governments, cryptocurrencies are decentralized and often free from central authority control. Bitcoin, Ethereum, and many others use cryptography to enable secure transactions and control new unit creation. The blockchain is a public ledger recording all transactions, preventing fraud and ensuring trust. Users can buy, sell, and trade cryptocurrencies through exchanges. Though volatile, crypto has gained popularity for its potential in finance, technology, and privacy, offering new ways to store value, make payments, and manage digital assets.
