According to Lookonchain, June 16 data shows that 10 Bitcoin (BTC) ETFs recorded a net inflow of 2,864 BTC, worth $305.87 million, with BlackRock's iShares ETF leading the surge by adding 2,272 BTC ($242.6 million) and reaching a total holding of 671,795 BTC ($71.74 billion). In contrast, 9 Ethereum (ETH) ETFs experienced a net outflow of 3,748 ETH ($9.84 million), driven mainly by Fidelity's ETF, which saw 3,496 ETH ($9.18 million) withdrawn and now holds 465,263 ETH. These ETF flows indicate strong institutional demand for BTC, supporting bullish trading sentiment, while continued ETH outflows may signal caution or profit-taking among Ethereum investors.
