According to online reports, Strategy founder Michael Saylor said that BlackRock's bitcoin exchange-traded fund iShares Bitcoin Trust (IBIT) will become the world's largest exchange fund (ETF) in the next ten years. IBIT's current market value has reached US$54 billion, with daily trading volume exceeding US$1.5 billion. In the past five trading days, the net inflow of U.S. spot bitcoin ETFs was approximately US$2.8 billion, of which IBIT accounted for US$1.3 billion, or one of the reasons driving the bitcoin price up from approximately US$85,000 to US$94,000. In addition, the annualized yield on the Bitcoin ETF carry trade of CME is close to 10%, indicating an increase in market risk appetite.
