The crypto market experienced a challenging start to the fourth quarter as major exchange-traded funds tied to Bitcoin, Ethereum, and Solana all closed October in negative territory. Despite earlier optimism surrounding potential autumn price rallies, macroeconomic pressures and shifting investor sentiment weighed heavily on digital asset products. Bitcoin and Ethereum ETFs suffered notable capital outflows following weeks of sustained volatility and cautious trading behavior. Meanwhile, Solana investment products also succumbed to the broader downward trend, halting their recent momentum. This synchronized monthly decline highlights the ongoing sensitivity of institutional crypto vehicles to wider financial market fluctuations.
