#BTCReserveStrategy Cryptocurrency is a type of digital or virtual currency that uses cryptography for security, making it difficult to counterfeit. Unlike traditional money, it operates on decentralized networks, typically based on blockchain technology—a public ledger that records all transactions. The most well-known cryptocurrency is Bitcoin, launched in 2009. Others include Ethereum, Binance Coin, and Ripple. Cryptocurrencies allow peer-to-peer transactions without banks, often with lower fees and faster transfers. They can be used for payments, investments, and smart contracts. However, they are highly volatile, and prices can change rapidly, making them risky but potentially rewarding for investors and traders.
