Performance is measured as the secondary market price return based on the official closing price on 1/11/24 through the official closing price on 12/31/24. Past performance does not guarantee future results.

Current performance may be higher or lower than the performance quoted. For the most recent month end performance please visit etfs.grayscale.com/gbtc GBTC, an exchange traded product, is not registered under the Investment Company Act of 1940 ("1940 Act") and therefore is not subject to the same regulations and protections as 1940 Act registered ETFs and mutual funds.
