BTC

Bitcoin is the world's first decentralized cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto, enabling peer-to-peer electronic cash transactions without intermediaries through a blockchain secured by Proof of Work mining and SHA-256 cryptography. With a fixed supply capped at 21 million coins and programmatic halvings every four years that reduce miner rewards, Bitcoin is designed as a deflationary digital asset often compared to "digital gold" for its scarcity properties. The network solves the double-spending problem without requiring trusted intermediaries, creating the first truly scarce digital asset with censorship resistance and permissionless access that no single entity can control. Bitcoin operates as a distributed ledger maintained by thousands of nodes globally, with transactions grouped into blocks added approximately every 10 minutes through competitive mining. The network has achieved mainstream adoption following institutional developments such as the 2024 SEC approval of spot Bitcoin ETFs and corporate treasury adoption, while the ecosystem continues to evolve with innovations like Ordinals and BRC-20 tokens enabling NFT and token functionality on Bitcoin, and emerging BTCFi protocols allowing staking mechanisms alongside traditional use cases. Bitcoin's security model and immutability have established it as the most widely recognized and utilized cryptocurrency globally.
