Ethereum spot ETFs have seen net outflows overall since their launch last month, while the spot bitcoin ETFs launched earlier this year have been more successful, JPMorgan said in a research note on Wednesday. Ethereum funds saw net outflows of about $500 million, while bitcoin ETFs saw net inflows of more than $5 billion. The bank said the weak data from the Ethereum ETF was somewhat expected, pointing to bitcoin's "first mover advantage", lack of staking, and lower liquidity implications.
