Crypto exchange-traded funds (ETFs) revealed a contrasting trend on May 13th, 2025, with Bitcoin and Ethereum ETFs experiencing separate dynamics. Spot Bitcoin ETFs recorded a net outflow of $96.14 million, signaling potential market uncertainty or investor profit-taking. Notably, none of the twelve spot Bitcoin ETFs displayed any positive inflows for the day. This was in stark contrast to Ethereum ETFs, which experienced a notable inflow of $13.37 million across nine ETFs, with no reported outflows. The divergence highlights growing interest in Ethereum, possibly fueled by anticipation surrounding potential US-based spot Ethereum ETFs or excitement about its long-term growth in DeFi and smart contracts.
