Bitcoin is the world's first and largest cryptocurrency by market capitalization, created in 2009 by the pseudonymous Satoshi Nakamoto. Bitcoin operates on a decentralized peer-to-peer network using proof-of-work consensus, with a hard supply cap of 21 million coins. It has evolved from a niche digital currency into a recognized store of value and inflation hedge, with spot Bitcoin ETFs approved in the US in January 2024 bringing institutional access.
Bitcoin's price is driven by institutional adoption (ETF flows, corporate treasury allocations), halving cycles (supply reduction every ~4 years, last in April 2024), Federal Reserve monetary policy and real interest rates, on-chain metrics (exchange reserves, whale accumulation, MVRV ratio), regulatory developments, and macro risk appetite. Mining hash rate and difficulty adjustments signal network health.
BTC is the most liquid cryptocurrency with 24/7 trading across global exchanges. It exhibits strong 4-year cyclical patterns around halvings. Funding rates on perpetual futures indicate short-term positioning extremes. BTC dominance (market cap share) rises during risk-off crypto periods and falls during altcoin rallies.
