Overview
Bitcoin is the first and largest cryptocurrency by market cap, created in 2009 as a peer-to-peer electronic cash system. It introduced blockchain technology and the concept of digital scarcity through its fixed 21 million coin supply. Bitcoin has evolved from an experimental payment system into the dominant store-of-value asset in crypto, often called "digital gold."
Who Created BTC?
Bitcoin was created by Satoshi Nakamoto and launched in 2009. It is a Layer 1 cryptocurrency using Proof of Work consensus.
Key Use Cases
Bitcoin provides censorship-resistant value storage and transfer outside the traditional banking system, accessible to anyone with internet access. Its fixed supply and predictable issuance schedule (halving every 210,000 blocks) make it a hedge against monetary inflation. Institutions use Bitcoin as a treasury reserve asset and as collateral in structured financial products.
