Overview
FBTC and GBTC both offer direct bitcoin exposure through ETF structures, but they differ fundamentally in age and cost. FBTC is Fidelity's newer entrant, launched in January 2024 with a spot bitcoin strategy and a 0.25% expense ratio. GBTC is Grayscale's established bitcoin trust, converted to an ETF in 2024 after over a decade as a closed-end fund, carrying a 1.50% expense ratio.
How they differ
The biggest difference is cost: FBTC charges 0.25% annually while GBTC charges 1.50%—a spread that compounds significantly over time on a $10 billion+ asset base. Both track bitcoin directly with nearly identical beta (FBTC at 1.8779, GBTC at 1.8866), so the performance difference hinges almost entirely on fees. FBTC is newer and smaller by AUM ($10.9B versus $8.37B), though both have crossed the $8 billion threshold needed for institutional scale. Neither fund distributes income, reflecting bitcoin's non-yielding nature. GBTC's longer track record—inception in September 2013—offers a decade-plus history, while FBTC brings Fidelity's operational infrastructure and compliance framework into a crowded bitcoin ETF space.
Who each is best for
FBTC: Fits investors seeking straightforward bitcoin exposure with minimal cost drag, particularly those building long-term cryptocurrency allocations in taxable accounts where fee efficiency compounds.
GBTC: Fits investors who prioritize Grayscale's established infrastructure and custodial track record over lowest fees, or those already holding shares from its closed-end fund era who value continuity.
Key risks to know
- Bitcoin volatility and beta concentration: Both funds exhibit beta near 1.88, meaning a 10% move in bitcoin produces roughly an 18% move in fund shares. Bitcoin itself trades in wide intraday and weekly ranges, amplifying portfolio swings.
- Fee drag on returns: The 125-basis-point expense ratio gap between FBTC and GBTC translates to meaningful drag over multi-year horizons; a 20% annual bitcoin return nets 19.75% in FBTC versus 18.5% in GBTC after fees.
- Regulatory and custody risk: Both funds hold physical bitcoin, exposing shareholders to regulatory changes in U.S. crypto policy and the operational security of their respective custodians.
- Ethereum and altcoin opportunity cost: Investors seeking cryptocurrency diversification beyond bitcoin may find single-asset exposure limiting if crypto market leadership shifts.
Bottom line
If minimizing cost drag is the priority, FBTC's 0.25% expense ratio offers a structural advantage over GBTC's 1.50%, particularly for long-term holders. If familiarity with Grayscale's operational history and custodial practices outweighs fee considerations, GBTC's track record since 2013 may appeal. Past performance doesn't predict future results, and bitcoin's regulatory environment remains unsettled.
