BitcoinBTC

Bitcoin is the world's first decentralized cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto. It enables peer-to-peer electronic cash transactions without intermediaries like banks or governments, operating on a blockchain secured by Proof of Work mining and the SHA-256 cryptographic algorithm. With a fixed supply cap of 21 million coins and programmatic halvings every four years that reduce miner rewards, Bitcoin is designed as a deflationary digital asset often called "digital gold." Its value stems from solving the double-spending problem without trusted intermediaries, creating the first truly scarce digital asset with censorship resistance and permissionless access that no government, corporation, or individual can control.

The structure read is liquidity-first: Atlas records circulating supply at 20.07M, total supply at 20.07M, and maximum supply as 21.00M. The market file is useful for comparing whether capitalisation, turnover, and supply profile are moving together or separating. The cached CoinGecko profile identifies genesis date 2009-01-03.

No material profile or tape break was detected versus the prior stored Atlas file. The permanent asset file remains stable; today's update refreshes the public market tape. This deterministic Atlas file is built from cached CoinGecko market and profile fields and is research-only. It does not add a trade recommendation, brokerage instruction, or valuation call.
