Ethereum (ETH) followed suit, trading at 3,250 USD on the ETH/USDT pair, up 2.8% during the same timeframe (Source: Binance, April 29, 2025). The massive market cap of USDT acts as a stabilizing force, reducing slippage in high-volume trades and enabling tighter spreads, which is critical for day traders and scalpers.

Traders should watch for USDT pair volume trends as a leading indicator of broader market movements, particularly in AI-related projects.
