Bitcoin trading occurs on exchanges. These exchanges accept your fiat currencies (like USD and EUR) in exchange for a cryptocurrency (like BTC). These exchanges maintain a liquid pool of bitcoin, allowing users to withdraw their bitcoin at any time. Investors who wish to trade on that exchange can deposit bitcoin into their personal wallet on the exchange, or make a wire transfer to the exchange’s bank account. The exchange notices this transfer, then credits your account.
