Bitcoin Price Today: Live BTC to USD Chart

What drives the Bitcoin price?

Bitcoin has no central issuer, so its price is set purely by supply and demand on crypto exchanges. The main drivers:

• Fixed supply: total supply is capped at 21 million BTC, and the roughly four-yearly halving cuts new issuance in half.
• Global liquidity and interest rates: falling rates tend to lift demand for risk assets.
• Institutional demand: spot Bitcoin ETFs and corporate treasuries add steady buying.
• Regulation: government decisions can move the price sharply.
• Sentiment: headlines and social media amplify short-term swings.

How to read the chart

The chart above shows daily closing prices for the last three months. The 3-month high and low give a quick sense of the recent trading range, while the 1-week and 1-month changes show momentum. Bitcoin trades around the clock, so the “daily” change is measured against the previous UTC close.

Before you buy Bitcoin

1. Accept the risk: Bitcoin has fallen more than 70% from its peak several times.
2. Keep it small: many advisers suggest crypto stays a single-digit share of a portfolio.
3. Use a reputable exchange: turn on two-factor authentication and consider self-custody for long-term holdings.
4. Track taxes: in the US, selling crypto at a gain is a taxable event.
