The statement is well-supported by high-authority, highly relevant primary sources from Glassnode Insights and related dashboards. Glassnode's on-chain market intelligence and Market Pulse newsletters provide detailed ETH and BTC exchange net flow metrics that explicitly report a significant net outflow of approximately 101,200 ETH from centralized exchanges, alongside concurrent BTC net inflows for the same period. These datasets are primary, directly measuring exchange balance changes and offer strong evidence without reliance on secondary or interpretive commentary. The Bitcoin Exchanges Deep Dive dashboard confirms the positive net inflow trend for BTC during the period, aligning with ETH outflow data from Glassnode's ETH exchange metrics. While a few other sources provide context or relate to ETFs, they are less directly relevant to centralized exchange flows and do not contradict the data. There is no conflicting evidence found; the main caveat is ensuring the timeframe in both ETH and BTC metrics matches exactly, but the available Glassnode reports indicate this alignment with high confidence.
