💡 What is Bitcoin?
Bitcoin is the first decentralized cryptocurrency, introduced by the pseudonymous developer Satoshi Nakamoto in 2009. It operates without a central authority or single administrator, enabling peer-to-peer (P2P) transactions over the Bitcoin network—a global, open-source, and permissionless blockchain.
Bitcoin was designed as a deflationary currency, with a fixed supply of 21 million coins. Its transparency, censorship-resistance, and finite supply have earned it the nickname “Digital Gold.”
