$BTC

The "best" Bitcoin trading pair depends on your specific goals and trading strategy. Here are some of the most popular and liquid options:

**Most Common BTC Pairs:**

- **BTC/USDT** - Highest liquidity, stable reference point, good for most trading strategies

- **BTC/USD** - Direct fiat pairing, popular on major exchanges like Coinbase

- **BTC/USDC** - Similar to USDT but backed by regulated reserves

**For Altcoin Trading:**

- **ETH/BTC** - Classic crypto-to-crypto pair, good for relative strength analysis

- **BTC/EUR** or **BTC/GBP** - If you're in Europe or UK respectively

**Considerations for choosing:**

- **Liquidity** - USDT pairs typically have the highest volume

- **Fees** - Some exchanges offer lower fees for certain pairs

- **Regulation** - USD pairs may be preferred for tax/regulatory clarity

- **Volatility** - Stablecoin pairs (USDT/USDC) offer more predictable pricing

For most traders, **BTC/USDT** is often considered the go-to pair due to its massive liquidity and tight spreads across virtually all major exchanges.
