$BTC $BTC is not just the first cryptocurrency, it is the benchmark for everything else. Trading any pair with Bitcoin —whether it's BTC/USDT, BTC/ETH, or even BTC/lesser-known altcoins— is like measuring the pulse of the crypto market. Every movement of its price resonates throughout the rest. When I analyze a pair with $BTC, I'm not just seeing if it goes up or down, I'm interpreting how the market values everything in comparison to the currency that started it all. For many, Bitcoin is the destination. For others, it is just the starting point. In my case, it remains both.
