$BTC

BTC pairs let you trade altcoins against Bitcoin instead of always using fiat money. This is handy if you want to boost your Bitcoin holdings while dealing in other cryptocurrencies.

- **Market Correlation Insights**: Altcoins don’t always move in the same way compared to Bitcoin as they do against USD. Trading BTC pairs can give you a better idea of these trends and might help you make some money.

- **Reduced Fiat Exposure**: If you're into crypto for the long haul but want to trade between different coins, BTC pairs keep you in the crypto world without needing to switch back to traditional money.

- **Arbitrage Opportunities**: Sometimes, you’ll see price differences between USD pairs and BTC pairs. These gaps can create chances to trade, especially when Bitcoin is fluctuating a lot.

- **Lower Fees on Some Exchanges**: A few platforms charge less for trading BTC pairs compared to fiat pairs, but this can change from one exchange to another.
