BlackRock's Bitcoin ETF has outperformed its competitor Grayscale by amassing $20 billion in assets. The world-renowned investment firm BlackRock has achieved a significant milestone by managing the IBIT ETF, which currently holds nearly 300,000 bitcoins. This achievement marks a remarkable success compared to other ETFs in the market. For instance, Fidelity's IBIT and FBTC ETFs garnered $6.5 billion within their first month of trading, surpassing the performance of 5,500 previously launched ETFs. The IBIT ETF launch stands out as the most successful in the history of ETFs, highlighted by the substantial difference between IBIT and the second fastest ETF to reach $20 billion in assets, which took JPMorgan's JIPO ETF 985 days compared to just 137 days for BlackRock's ETF.
