According to Farside Investors, BlackRock's dominance in the Bitcoin ETF market through $IBIT may not be favorable for the broader Bitcoin ecosystem. They point out that while $IBIT offers lower trading spreads, rival ETFs like $BITB and $HODL present lower management fees and actively support Bitcoin development. For long-term investors, switching to $BITB and $HODL could be advantageous despite slightly higher spreads, as these funds contribute to the sustainability of Bitcoin infrastructure and may offer better fee structures over time (source: Farside Investors, Twitter, May 3, 2025).
