Market participants caution that while Ethereum ETFs are outperforming Bitcoin, the broader crypto market remains sensitive to macro conditions. Stablecoin inflows have risen to $379 million as of August 31, suggesting investors are preparing for a potential Fed policy pivot. However, altcoin inflows have increased to 55,000 transactions per week, signaling rotation into riskier assets. This divergence underscores the need for diversified strategies as investors navigate the interplay between ETF flows, Fed policy, and altcoin volatility.
