Share prices come from public stock-market data with a short delay; coin prices come from public exchange data. Estimated NAV per share = coins per share × the live coin price, using reference figures from the latest public fund data (17 Jul 2026) that drift slowly as fees accrue. Grayscale trusts trade over the counter and can be illiquid, so quotes can be stale and premiums exaggerated. For information and education only, not financial advice.
