According to crypto.news, several developments emerged in the crypto industry this week. The latest weekly fund flow data for Bitcoin and Ethereum ETFs showed combined net outflows of $1.65 billion for the week, with BlackRock's IBIT recording consecutive outflows. Follow-up data on the Binance hack showed that Santiment recorded capital outflows and deteriorating social sentiment, while futures traders still held multi-billion-dollar positions. The U.S. crypto 401(k) rule has entered final White House review; if the Department of Labor's final rule takes effect, it would make it easier for employers to offer crypto asset exposure in 401(k) plans. Ethereum has delayed the Glamsterdam upgrade, with the Hoodi testnet postponed and eight smart contract risks still to be assessed. The People's Bank of China halted a Solana Shanghai promotional event, and the relevant marketing entities are under investigation. These events cover ETF fund flows, exchange security follow-up, retirement fund rules, public blockchain technical upgrades, and public blockchain marketing regulation.
On ETF fund flows, Bitcoin and Ethereum ETFs recorded combined weekly net outflows of $1.65 billion, the core fact in this dataset. Compared with earlier scattered reports of single-day ETF outflows, this disclosure uses a more complete weekly basis and combines observations of fund inflows and outflows. Cumulative weekly net outflows better reflect the overall direction of fund flows within a week than single-day data and reduce the noise from single-day subscription and redemption fluctuations. This round of outflows involves both Bitcoin- and Ethereum-related ETFs, rather than being limited to a single asset class, so its impact on market sentiment and liquidity has drawn attention. BlackRock's IBIT recorded consecutive outflows, corroborating the overall weekly net outflows. The source material did not give the specific start and end dates of the statistical period, nor did it separately disclose the net outflow scale for Bitcoin ETFs and Ethereum ETFs, or IBIT's share of total outflows, the number of consecutive outflow weeks, or the single-week outflow amount. In terms of market impact, fund outflows directly affect Bitcoin and Ethereum liquidity and market sentiment. The source material places liquidity impact alongside market sentiment, indicating that this round of changes is not only a fluctuation in fund data but also involves changes in the trading environment and participant expectations. Earlier single-day ETF outflow reports contained duplicated information; this time the most complete weekly data was retained, shifting the observation basis from single-day fluctuations to weekly cumulative changes. For Bitcoin and Ethereum, the direction, scale, and persistence of ETF fund flows are important references for assessing the short-term market environment.
On the Binance hack follow-up, Santiment data showed capital outflows and deteriorating social sentiment after the event. At the same time, futures traders still maintained multi-billion-dollar positions, and futures holdings had not clearly withdrawn. This set of data reflects market sentiment and liquidity conditions after the Binance event. The source material did not provide the specific time of the Binance hack, the amount involved, or the Santiment statistical period. Based on available information, capital outflows and deteriorating social sentiment coexisted, while futures positions had not clearly withdrawn, indicating that spot-related sentiment indicators and futures position changes were not fully synchronized.
The U.S. crypto 401(k) rule has entered final White House review. The U.S. Department of Labor's final rule has entered the White House review stage; if ultimately implemented, it would make it easier for employers to offer crypto asset exposure in 401(k) plans. The source material lists the rule as a potential source of incremental institutional capital, with significant regulatory impact. The rule is part of the advancement of a framework for retirement funds to enter the market. The source material did not disclose the completion time of the White House review, the effective date of the rule, or specific applicable conditions.
Ethereum has delayed the Glamsterdam upgrade. Glamsterdam is an important Ethereum upgrade. The postponement of the Hoodi testnet involves gas accounting and smart contract security assumptions, and eight smart contract risks are still to be assessed. This change affects ETH's technical roadmap, developer deployment, and upgrade expectations. The source material did not provide a new timetable after the delay or elaborate on the specific content of the eight smart contract risks.
The People's Bank of China halted a Solana Shanghai promotional event. Chinese regulators halted the Solana Shanghai promotion and are investigating related entities. The source material lists this as a regulatory action directly targeting public blockchain marketing, which may affect SOL and expectations for projects in China. The source material did not disclose the specific names of the entities under investigation, the progress of the investigation, or the original time of the event.
Areas to watch include: whether subsequent weekly net outflows from Bitcoin and Ethereum ETFs continue, whether BlackRock's IBIT consecutive outflows change, and how fund changes transmit to Bitcoin and Ethereum liquidity and market sentiment; whether capital outflows and social sentiment after the Binance event change further, and whether futures positions adjust significantly; whether the U.S. crypto 401(k) rule passes final White House review; progress in risk assessment for Ethereum's Glamsterdam upgrade and Hoodi testnet; and the progress of the investigation after the Solana Shanghai promotional event was halted and its impact on related projects. The existing source material does not provide follow-up forecasts; the above directions are only for tracking changes in the events.
