BlackRock has transferred 44,140 ETH, worth approximately $135.36 million, to Coinbase, sparking concerns over Ethereum's price stability. This transaction coincides with significant outflows from the BlackRock Ethereum ETF (ETHA), which reported $88.7 million in net outflows. Despite the recent listing of Ethereum ETFs by Vanguard, analysts caution that breaching the $3,000 support level could lead to a further decline to $2,800. The sell-off by BlackRock has contributed to an 11% drop in Ethereum's price earlier this week, as on-chain data indicates a reduction in their ETH holdings. While Ethereum's Fusaka upgrade aims to enhance scalability, the market sentiment remains bearish amid these developments.
