Fees, spread and why quotes differ

The rate on this page is a market reference rate. When you trade, an exchange adds a trading fee (commonly 0.1%–0.6% on spot markets), and payment-card or bank-transfer purchases usually carry a higher spread. Withdrawal and network fees also apply. Because of this the amount you receive will normally be a little lower than the headline conversion; for large amounts, compare several venues and use limit orders where possible.

What moves the USD/BTC rate?

Crypto prices respond to market-wide sentiment, liquidity, news and regulation, and to coin-specific events such as upgrades, listings and token unlocks. The USD side also changes with foreign-exchange rates, so the same coin can move differently in different currencies. This is general information, not financial advice.
