Ethereum price remains under pressure as institutional flows weaken and developers postpone the next stage of Glamsterdam testing. The Investing.com market page displayed Ether at USD 2,133.46, a reported 24-hour decline of 4.48 percent, and a market capitalization of USD 271.68 billion. The page also showed 24-hour trading volume of USD 3.38 billion and ranked Ethereum second among the listed cryptocurrencies.
Upgrade delay puts testing first
The Ethereum Foundation said on November 6 that Glamsterdam was being tested on public testnets. Chainsecurity had identified projects that could become vulnerable because they relied on invariants affected by EIP-8037 and EIP-8038. Those proposals change how gas is charged for certain operations and for state.
As a result, Ethereum's all-core-developers process decided to delay the hardfork process and not activate Glamsterdam on the Hoodi testnet until the issues are resolved. The Foundation said work on the separate Hegota upgrade would continue in parallel. No new Hoodi activation date was stated in the announcement, so the delay should be treated as a development and testing issue rather than as a scheduled mainnet change.
ETF flows remain a headwind
Investor demand through U.S. spot Ether ETFs also remained negative. According to TokenPost, the products recorded combined net outflows of USD 93.19 million on November 6. BlackRock's ETHA accounted for USD 90.76 million of the withdrawals, while ETHB recorded an inflow of USD 1.15 million. The November 6 result followed USD 99.9 million of net outflows on November 5. Cumulative net inflows since launch stood at USD 11.92 billion, while the products held USD 12.84 billion in net assets.
What investors should watch
For investors tracking the Ethereum price, the immediate focus is whether ETF redemptions persist and whether developers can resolve the contract-compatibility concerns without extending the testnet delay. The upgrade issue does not itself establish a mainnet timetable or a direct token-price effect. It does, however, make execution and security testing important factors alongside liquidity and risk appetite. A recovery case would require improving fund flows and credible progress on the upgrade process; continued outflows would leave ETH exposed to further volatility.
