$BTC Here's a concise summary of BTC trading pairs:

### Bitcoin (BTC) Trading Pairs

**Core Concept**: Shows how much BTC is needed to buy 1 unit of another cryptocurrency (e.g., ETH/BTC = 0.063 means 1 ETH costs 0.063 BTC).

**Key Points**:

1. **Liquidity Hub**: Most altcoins trade directly against BTC, making it the crypto market’s benchmark.

2. **Efficiency**: Avoids double fees (no need to convert to USD/stablecoins first).

3. **Market Signal**: Rising altcoin/BTC = altcoin strength; Falling = BTC dominance.

4. **Top Examples**: ETH/BTC, USDT/BTC, XRP/BTC, LTC/BTC.

5. **Risk**: Volatility in BTC amplifies altcoin pair swings.

> 💡 **Use**: Track pairs on exchanges like Binance or tools like CoinMarketCap.

*Bottom Line*: BTC pairs enable efficient trading but require volatility management.
