Btc Price Usd

BTC-USD constitutes the primary trading pair denominating Bitcoin value in United States dollars. Spot markets execute immediate Bitcoin-for-dollar exchanges at current market rates. Futures contracts obligate buyers to purchase Bitcoin at predetermined prices on specified settlement dates. Perpetual swaps mimic futures exposure without expiration dates, using funding rate mechanisms to anchor prices to spot. Positive funding rates require long position holders to pay short position holders every eight hours. Negative funding rates reverse payment flows, compensating long holders during bearish sentiment periods. Basis spread measures price difference between futures contracts and spot rates. Contango describes futures trading above spot, indicating bullish forward expectations. Backwardation describes futures trading below spot, signaling bearish sentiment or immediate demand.
