币界网报道：Crypto ETFs are gaining innovative features to enhance efficiency and investor appeal, according to industry reports. Several providers are introducing auto-rebalancing mechanisms that adjust holdings based on market conditions without manual intervention. New products also incorporate tax-loss harvesting strategies, automatically selling assets at a loss to offset capital gains taxes. Some ETFs now offer tiered fee structures, reducing costs for long-term holders. Providers are experimenting with "smart beta" approaches that weight assets by factors beyond market capitalization, such as liquidity or network activity. These developments come as crypto ETF assets under management surpassed $50 billion globally, with BlackRock's IBIT leading at over $20 billion. Analysts note these features address traditional investor concerns about volatility management and tax efficiency in digital asset exposure. The innovations mirror sophistication seen in conventional ETF markets, signaling maturation of crypto investment products.
