In cryptocurrency trading, a trading pair (such as BTC/USDT) consists of a base asset (BTC) and a quote asset (USDT), where the former is the trading subject and the latter is the pricing unit. The choice of trading pair directly affects the execution efficiency of strategies and risk management.

I prefer stablecoin trading pairs (such as BTC/USDT) because they have lower volatility and can more clearly reflect the true rise and fall of the base asset, avoiding the interference of dual-coin volatility in judgment. On the other hand, coin-to-coin pairs (like ETH/BTC) are suitable for arbitrage or bullish scenarios for the quoted coin.
