$BTC Trading in the $BTC pair means exchanging other cryptocurrencies against Bitcoin rather than fiat currencies like USD. It's a common strategy on many crypto exchanges where altcoins are listed with BTC trading pairs. Traders watch how altcoins perform relative to BTC, not just in USD value. A strong $BTC can weaken altcoin pairs, while a drop might boost altcoin gains. Technical analysis, trend strength, and BTC dominance charts help guide decisions. Successfull pair trading requires understanding market cycles and Bitcoin’s influence. It’s ideal for seasoned traders looking to grow their BTC holdings rather than cashing out to fiat.
