BTC USD Price

BTC-USD spot price establishes baseline valuation from which derivatives contracts derive their pricing. Futures premiums add or subtract from spot based on interest rates, storage costs, and directional sentiment. Options contracts grant holders rights to buy or sell Bitcoin at strike prices before expiration dates. Call options profit when Bitcoin rises above strike prices; put options profit when Bitcoin falls below strikes. Implied volatility extracts market expectations of future price movement magnitude from options premiums. Volatility skew compares implied volatility across different strike prices, revealing directional bias. At-the-money options carry highest time value; out-of-the-money options cost less but require larger moves. Max pain theory identifies strike prices where most options expire worthless, minimizing dealer payouts. Greeks measure options sensitivity: delta tracks directional exposure, theta measures time decay, vega quantifies volatility impact.
