[Bitcoin ETF Fund Inflows to Exceed 70% in 2025, Ethereum Gradually Increasing Its Share] According to The Block, spot Bitcoin and Ethereum ETFs are expected to attract approximately $31 billion in fund inflows in 2025. Bitcoin's annual ETF market share is projected to remain stable at around 70%-85%, solidifying its position as the primary allocation target for institutions entering crypto assets. Ethereum ETF's share is estimated to fluctuate between 15%-30%, indicating a gradual increase in institutional acceptance of ETH, though it still lags behind Bitcoin. The report highlights that institutional ETF purchases provide ongoing support for Bitcoin's price, with many viewing it as a macro hedge or "digital commodity." Meanwhile, ETFs for long-tail assets such as XRP, SOL, LINK, LTC, and DOGE currently hold very low market shares, with most products expected to be approved and launched by the end of 2025.
