$BTC A BTC pair (like BTC/ETH or BTC/SOL) lets you trade altcoins directly against Bitcoin instead of fiat (like USD or INR). Here's why BTC pairs matter:

✅ Benchmark Value: BTC is the dominant crypto asset — tracking altcoins against BTC shows real strength, not just dollar value.

✅ Altcoin Season Clue: If many altcoins rise in BTC pairs, it may signal the start of an altseason.

✅ Better Arbitrage: Traders use BTC pairs to spot price gaps across exchanges for profit.

✅ BTC Dominance Indicator: Watch BTC pairs to understand if capital is flowing into BTC or altcoins.
