Institutional investors are increasingly incorporating Bitcoin and Ethereum into their portfolios, with significant capital shifts observed in Q3 2025. On-chain data indicates that whale holdings of Bitcoin surged by 53,600 BTC, now accounting for 67.77% of the total supply, according to Incrypthos. Ethereum has also attracted institutional interest, highlighted by a single-day ETF inflow of $338.8 million, as reported by Yahoo Finance. This trend raises questions about whether such large-scale accumulation signals a tactical entry point for institutions in the current crypto market cycle. Historical data suggests that whale activity often precedes bull markets, and current metrics, including the Network Value to Transactions (NVT) ratio, indicate ongoing accumulation. Factors such as ETF inflows, regulatory clarity, and macroeconomic conditions like Federal Reserve rate cuts further support this institutional entry.
