$BTC refers to the exchange rate of Bitcoin (BTC) against another currency. In practice, whenever you see BTC/XXX (where "XXX" is another currency), it indicates a trading pair in the cryptocurrency markets.

Examples of BTC Currency Pairs

Most Common Pairs:

BTC/USD Bitcoin against the US dollar (it is the most traded pair in the world).

BTC/BRL Bitcoin against the Brazilian real.

BTC/USDT Bitcoin against Tether (a stablecoin pegged to the dollar).

BTC/ETH Bitcoin against Ethereum.

How do currency pairs work?

Example BTC/USD:

If the exchange rate is 70,000, this means that 1 BTC = 70,000 US dollars.

Trading:

You can buy BTC by paying with the currency of the pair (for example, buying BTC using dollars in the BTC/USD pair) or sell BTC and receive the other currency.
