Institutional net outflows constrain US crypto-ETFs: bitcoin leads with inflows of $265 mln

February cash flows into U.S. spot cryptocurrency ETFs indicate a large-scale reallocation of net assets toward digital assets. The biggest wave of capital went into bitcoin, which has established itself as the leader among institutional investors, while Ethereum and other altcoins received less significant inflows. Data from crypto analyst Crypto Patel reveal how major players are restructuring their portfolios.

Spot Bitcoin ETFs Attracted Record Net Assets in February

On February 26, 2026, U.S. spot bitcoin ETFs showed the largest capital inflow among all crypto products. Bitcoin ETFs collected inflows of +3,740 BTC, worth approximately $254.4 million. In comparison, this amount is nearly equivalent to eight days of global bitcoin mining output, indicating concentrated buying activity.

Ethereum ETFs followed with inflows of +3,210 ETH totaling $6.6 million, while other altcoins showed much more modest figures. Solana ETFs received +5,681 SOL ($0.5 million), XRP ETFs — +848,590 coins ($1.22 million), and Chainlink ETFs — +266,830 LINK ($2.42 million). This imbalance in net asset inflows clearly demonstrates that bitcoin remains the primary investment target for large portfolio managers.

BlackRock and Bitwise Strengthen Positions: How Institutional Funds Are Restructuring Portfolios

Against the backdrop of overall inflows, BlackRock had the most significant impact, purchasing +4,060 BTC worth $275.8 million and an additional +7,440 ETH worth $15.3 million. These large acquisitions in a single day indicate the firm’s confident stance on the long-term potential of cryptocurrencies. Bitwise also showed active buying, making substantial contributions to the overall inflow.

Interestingly, some competitors, such as Fidelity and ARK 21Shares, adopted a different strategy. These funds recorded net sales of bitcoin positions but increased exposure to ethereum. This diversification of net assets between bitcoin and ethereum reflects differing investor outlooks on near-term market dynamics.

What Rising Net Assets Mean for Ethereum and Altcoin Markets

The disproportion in net asset distribution between bitcoin and ethereum sparks a discussion about competitive advantages in the crypto market. Despite growing long-term interest in ethereum, current institutional capital dynamics clearly favor bitcoin as the most liquid and less volatile asset among cryptocurrencies.

Inflows into altcoins (DOGE, LTC, AVAX, HBAR) remained zero or near zero, indicating that institutional demand is concentrated mainly on two leaders — bitcoin and ethereum. Positive flows into Chainlink ETFs at $2.42 million are an exception, confirming LINK’s specialized status within the DeFi ecosystem.

As of March 2026, current prices show bitcoin at $70,990 with a 24-hour trading volume of $1.06 billion, while ethereum trades at $2,160 with a volume of $499.31 million. These figures reflect market stabilization after February’s capital flows, although the trend in net assets continues to be a critical indicator of institutional sentiment.

This scenario suggests that institutional ETF assets will continue to drive the pace of the crypto market, with bitcoin maintaining its role as the primary reserve for large capital flows, while altcoins will have a dependent status within the ecosystem.
