$BTC The "BTC pair" in Spanish refers to a trading pair of Bitcoin. In cryptocurrency trading, a trading pair shows the value relationship between two different cryptocurrencies or between a cryptocurrency and a fiat currency (such as the dollar or euro).

It indicates how much of the quote currency (the second currency in the pair) is needed to buy one unit of the base currency (in this case, Bitcoin - BTC).

Here are some common examples of BTC trading pairs:

* BTC/USD: Bitcoin against the US dollar. This pair shows how many US dollars you need to buy one Bitcoin.

* BTC/EUR: Bitcoin against the euro.

* BTC/ETH: Bitcoin against Ethereum. This pair shows how much Ethereum you need to buy one Bitcoin.

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