最新报道:The U.S. SEC has approved a tenfold increase in the options trading limit for BlackRock's spot Bitcoin ETF (IBIT), raising the cap from 25,000 to 250,000 contracts. This decision significantly enhances liquidity and trading flexibility for the ETF, which currently holds over $18 billion in assets under management. The move follows strong demand from institutional investors and marks a major step in mainstream Bitcoin adoption. Analysts suggest this could lead to increased volatility but also greater market participation. BlackRock's IBIT remains the largest Bitcoin ETF by AUM since its January launch.
