$BTC Bitcoin (BTC) is a decentralized digital currency that operates on blockchain technology, enabling peer-to-peer transactions without intermediaries. To pair BTC means to trade it against another asset, like fiat (USD, EUR) or other cryptocurrencies (ETH, USDT). Popular BTC trading pairs include BTC/USD, BTC/EUR, and BTC/USDT on exchanges like Binance, Coinbase, and Kraken. Traders analyze price charts, liquidity, and volatility to execute buy/sell orders. Pairing BTC involves market orders (instant execution) or limit orders (set price). Factors like exchange fees, order books, and trading volume influence strategies. BTC's scarcity (21M cap) and adoption drive its value, making it a key asset in crypto markets.
