Bitcoin ($BTC ) remains the king of all cryptocurrencies. It is the first and most trusted digital asset by both institutional and retail investors. When I trade using the $BTC pair, I focus on market structure, volume, and price action. I usually pair BTC with altcoins like ETH or LINK to catch opportunities when those coins move faster than BTC. Watching BTC dominance and funding rates also gives me a clue about overall market sentiment. BTC is not just a coin; it is a benchmark for the whole market. Every serious crypto trader must watch the $BTC chart to guide their trades.
