Ethereum reserves across crypto exchanges fall to multiyear low as 30-day average drops to 14,742,387.9 ETH

AI Market Summary
Exchange-held ETH supply fell to a multiyear low, with the 30-day average down ~30% since mid-2025 and notable declines on Binance, signaling sustained net outflows to self-custody or longer-term holding. Historically, shrinking exchange reserves can tighten liquid supply and reflect improving demand conditions. Reported multi-month inflows into BlackRock's iShares Ethereum Trust (ETHA) reinforce the institutional accumulation narrative despite recent price weakness.
