The price of Ethereum (ETH) is falling in line with the broader weakness in the virtual asset market.

As rising oil prices and U.S. Treasury yields push investors away from risk assets, Ethereum's price has remained weak despite inflows into Ethereum exchange-traded funds (ETFs) and the scheduled launch of the Sepolia testnet on October 6 (local time). Ethereum was trading at $2,660 as of 10:29 p.m. Korean time on the 24th.

■ Sepolia on October 6, Holesky on the 27th… Mainnet Before Q4 2026

According to overseas crypto media outlet Cointelegraph (KoinGap), Ethereum will begin the first public testnet operation for the 'Glamsterdam' upgrade on October 6 (local time). On the Sepolia testnet, developers will test whether the Glamsterdam upgrade works without issues with existing Ethereum smart contracts.

Ethereum is then scheduled to go through the Holesky testnet on October 27 (local time). In this second test environment, the upgrade will be tested for its impact on interactions between different blockchains. Once both testnet phases are passed, the Glamsterdam upgrade is expected to be applied to the mainnet before the end of the fourth quarter of 2026.

Cointelegraph reported that Glamsterdam will be one of the largest upgrades to Ethereum since The Merge in 2022. Glamsterdam aims to reduce transaction costs and triple throughput, which could in turn increase usage of the Ethereum network. The upgrade comes as Ethereum co-founder Vitalik Buterin focuses on strengthening the network's defenses against quantum computer attacks.

■ 30-Day Realized Volatility at 0.73… "Direction Hard to Predict"

According to Cointelegraph, citing data from CryptoQuant, Ethereum's 30-day realized volatility measured on Binance rose to 0.73, the highest level since March 2026. This expansion in volatility came as Ethereum's price fluctuated between $1,800 and $2,800 between August and September 2026.

However, according to analysis by CryptoQuant analyst Barak Charna cited by Cointelegraph, the increased volatility alone does not indicate whether Ethereum's price will rise or fall. Barak Charna explained that continued volatility expansion could serve as a signal that appears before larger movements in Ethereum's price.

According to Cointelegraph, Ethereum has recorded a return of 6.94% so far in September 2026, the highest September return since 2016.

■ 4 Consecutive Weeks of ETF Inflows… BlackRock Net Assets Near $9.7 Billion

According to Cointelegraph, citing data from SoSoValue, Ethereum ETFs have seen inflows for four consecutive weeks. Cointelegraph explained that this fund flow shows growing institutional demand for Ethereum ETFs.

The net assets of BlackRock's Ethereum Trust (ETHA) stand at $9.7 billion, approaching $10 billion. In addition, according to Cointelegraph, $53 million has flowed into the Morgan Stanley Ethereum ETF launched in July 2026, narrowing the gap with Franklin Templeton's ETF, which has seen inflows of $59 million.
