最新报道:BlackRock's iShares Bitcoin Trust (IBIT) now holds over 662,500 BTC, valued at approximately $72.4 billion, representing more than 3% of all Bitcoin. This marks the fastest-growing ETF in history, achieving in 341 days what took SPDR Gold Shares 1,600 trading days. The firm attributes Bitcoin's growing appeal to improved price discovery, deeper liquidity, and potential stability from broader institutional adoption. BlackRock recommends allocating 1-2% of traditional portfolios to Bitcoin, citing its scarcity and hedge against dollar devaluation. However, concerns persist about centralization as major institutions dominate holdings, alongside regulatory uncertainties highlighted by officials like Commissioner Caroline Crenshaw.
