FAQ
Why is GBTC’s share price lower than expected?
GBTC charges a 1.50% annual expense ratio — six times higher than most competitors. This fee continuously reduces the BTC-per-share ratio, dragging down returns over time. See our fee drag guide for a detailed breakdown.
Should I switch from GBTC to a cheaper Bitcoin ETF?
It depends on your tax situation. Selling GBTC triggers capital gains tax. If you have large unrealized gains, the tax bill may outweigh years of fee savings. See our tax guide for details.
What is the Grayscale Bitcoin Mini Trust (BTC)?
BTC is a low-fee (0.15%) Bitcoin ETF spun off from GBTC. Grayscale distributed Mini Trust shares to existing GBTC holders as a lower-cost alternative.
How do I convert GBTC shares to Bitcoin?
Multiply your shares by the BTC-per-share ratio shown above. GBTC has a different ratio than other ETFs due to its legacy trust structure — don’t compare share prices directly.
