Cryptocurrency represents a groundbreaking shift in how we perceive and use money. As a decentralized digital currency, it relies on cryptography for security and operates without central bank oversight. Born in 2009 under the pseudonym Satoshi Nakamoto, cryptocurrency emerged as both a response to financial instability and a solution for borderless, low-cost transactions.
Understanding Cryptocurrency Fundamentals
At its core, cryptocurrency is a peer-to-peer electronic cash system that eliminates intermediaries. Bitcoin remains the most prominent example, but alternatives like Ethereum, Litecoin, and Ripple have expanded the ecosystem. These digital currencies leverage blockchain technology—a distributed ledger system that ensures transparency and security.
