$BTC Let’s break down TradingPairs101. Every crypto trade involves a pair—like BTC/USDT or ETH/BTC. The first asset is what you're buying or selling, and the second is what you're using to measure its value. For example, in BTC/USDT, you’re trading Bitcoin against Tether (a stablecoin). Understanding trading pairs helps you spot opportunities, especially when moving between altcoins without converting back to fiat. It also affects fees, liquidity, and strategy. Pro tip: always check the volume and price spread before entering a trade. Mastering trading pairs is key to smarter moves in crypto. Which pairs are your go-to?
