最新报道:Bitcoin ETFs in 2025 offer investors a bridge to digital assets with varied cost structures and risk management features. iShares Bitcoin Trust (IBIT) charges 0.25%, Fidelity’s FBTC at 0.25%, and Grayscale’s BTC at 0.15%. Structured ETFs like Calamos Bitcoin 90 Series (CBXY) provide 90% downside protection with a 24.70% cap on gains. Bitcoin ETFs show an average annual return of 81.6%, slightly below direct Bitcoin’s 87.3%, but with better risk-adjusted metrics (Sharpe Ratio of 1.32 vs. 1.27). Regulatory clarity from the GENIUS Act and institutional adoption, with $12 billion inflows into IBIT year-to-date, bolster sustainability. Future growth hinges on structured innovations and favorable policies.
