Bitcoin

Bitcoin is the first and largest cryptocurrency, and its price is set around the clock by global supply and demand across spot exchanges. Because bitcoin never closes, the figure at the top of this page reflects the live US-dollar spot price aggregated from major market-data providers, updated continuously so it stays close to what is actually trading.

Bitcoin's supply is capped at 21 million coins and new issuance is cut in half roughly every four years, an event known as the halving. This predictable, disinflationary schedule is a big part of why companies have started holding bitcoin as a long-term treasury reserve asset.

Beyond spot price, the derivatives market reveals how traders are positioned. Funding rates are the periodic payments exchanged between long and short traders in perpetual futures: when funding is positive, longs pay shorts, which usually signals bullish leverage. Open interest is the total value of outstanding futures contracts and shows how much leverage is active — rapid changes can precede volatile moves and liquidations.

The Fear & Greed Index distills sentiment into a single score from 0 to 100. Readings under about 25 indicate extreme fear, while readings above about 75 indicate extreme greed. It blends volatility, momentum, volume, social signals and bitcoin dominance, and is often used as a contrarian gauge: extreme fear can accompany local bottoms, extreme greed local tops.

The Bitcoin network's health is visible directly on-chain. Hashrate measures the total computing power securing the network; a rising hashrate means more miners are competing to validate blocks, which strengthens security. Mining difficulty automatically adjusts about every two weeks so that blocks continue to arrive roughly every ten minutes, regardless of how much hashrate joins or leaves.

Transaction counts and block activity show how much the network is being used, while the countdown to the next halving marks the next scheduled reduction in new supply. Together these metrics give a fuller picture than price alone of how robust and active Bitcoin is at any given moment.
