The ticker symbol that represents Bitcoin on cryptocurrency exchanges is BTC.
BTC is the short market identifier used for Bitcoin in trading pairs, price listings, wallets, and financial data services. For example, BTC/USD represents the exchange rate between Bitcoin and the US dollar.
The symbol is distinct from Bitcoin’s smallest unit, the satoshi, which equals one hundred-millionth of a bitcoin. It is also different from a blockchain address, which is a longer string used to receive funds. Some services use XBT as an alternative symbol, particularly in financial-market contexts, but BTC is the overwhelmingly common cryptocurrency ticker.
Bitcoin’s symbol is often written with a capital B and lowercase or uppercase letters depending on the platform. The asset itself was introduced in 2009, while the ticker is now standard across exchanges and market-data websites.
