Key Stats
How the GBTC Ratio Works
The BTC-per-share ratio represents the exact amount of Bitcoin that backs each GBTC share. NAV-derived ratio, calibrated daily is used to determine this value. The ratio decreases slowly over time as the 1.50% annual management fee is deducted from fund assets.
How to Convert GBTC Shares to BTC
Shares to BTC: Multiply the number of shares by the BTC-per-share ratio.
Example: 100 GBTC shares × 0.00077 = 0.0770 BTC
Strike to BTC price: Divide the GBTC strike price by the ratio.
Example: $77 strike ÷ 0.00077 ≈ $100,000 BTC
Shares per 1 BTC: 1 ÷ 0.00077 ≈ 1,299 shares
