Comparisons6 min readUpdated March 17, 2026

Key Takeaways

✓IBIT charges 0.25% while GBTC charges 1.50% — a massive fee difference for identical Bitcoin exposure.
✓IBIT (BlackRock) has attracted more assets and offers better liquidity than GBTC.
✓GBTC was the original Bitcoin fund but its high fee has driven outflows since spot ETF competition arrived.
✓Both hold actual Bitcoin in custody, providing the same fundamental exposure.

The launch of spot Bitcoin ETFs in January 2024 gave investors a choice for the first time: stick with the original GBTC or switch to newer, cheaper alternatives like IBIT. The decision comes down to one primary factor: fees.

The Fee Gap

IBIT (iShares Bitcoin Trust) charges 0.25%. GBTC (Grayscale Bitcoin Trust) charges 1.50%. Both hold the same asset — actual Bitcoin in secure custody. The 1.25% annual fee difference means GBTC costs six times more for identical exposure. On a $10,000 investment, GBTC costs $150 per year versus $25 for IBIT.

Why GBTC Still Has Assets

Despite massive outflows, GBTC retains significant assets because many holders have large unrealized gains from buying years ago when GBTC was the only option. Selling to switch triggers capital gains taxes that may exceed several years of fee savings. These investors are economically locked in until they can harvest losses or wait for a tax-advantaged event.

Tracking and Liquidity

Both funds track Bitcoin's spot price accurately now that both operate as proper spot ETFs. IBIT has attracted the most assets and trading volume of any spot Bitcoin ETF, providing the tightest bid-ask spreads. GBTC's volume, while still meaningful, has declined as assets have migrated to cheaper alternatives.

Other Competitors

FBTC (Fidelity) also charges 0.25% and offers strong liquidity. Several competitors have offered temporary fee waivers to attract early assets. For new Bitcoin ETF purchases, compare IBIT, FBTC, and other low-fee options. GBTC should only be held if the tax cost of switching exceeds the fee savings. More at our education center.

Frequently Asked Questions

Why is GBTC so much more expensive?

GBTC originally operated as a closed-end trust with a 2% fee, later reduced to 1.50%. It had first-mover advantage and no competition. When spot Bitcoin ETFs were approved in January 2024, competitors launched at much lower fees. GBTC has lost significant assets as investors switch to cheaper alternatives like IBIT.

Is there any reason to choose GBTC over IBIT?

For most investors, no. IBIT offers the same Bitcoin exposure at a fraction of the cost with better liquidity. The only scenario favoring GBTC is if you already hold it in a taxable account with significant unrealized gains — selling to switch would trigger taxes that might exceed the fee savings for several years.

Which Bitcoin ETF has the best tracking?

IBIT and other low-fee spot Bitcoin ETFs track Bitcoin's price very closely, with tracking difference near their expense ratio. GBTC also tracks well now that it converted to a spot ETF, but its higher fee creates more drag. For pure tracking quality, the cheaper funds win by default.
