Grayscale Investments operates the longest-running regulated crypto investment vehicles in the United States. Founded in 2013 and headquartered in Stamford, CT, Grayscale pioneered the closed-end crypto trust structure that gave US-domiciled investors regulated Bitcoin exposure long before the spot ETF was approved. In January 2024 Grayscale converted its flagship Bitcoin Trust (GBTC) into a spot ETF.
GBTC began trading in 2013 as a private placement and was uplisted to OTC markets in 2015. After a successful court challenge to the SEC, it was converted to a spot ETF on January 11, 2024 and now trades on NYSE Arca. GBTC carries a 1.5% expense ratio — significantly higher than newer competitors — which has driven steady net outflows since conversion as legacy holders rotate to lower-fee alternatives.
Grayscale was the dominant US crypto trust for nearly a decade and still ranks in the top three for spot Bitcoin ETF AUM despite ongoing outflows. Investors evaluating GBTC versus newer products like BlackRock IBIT and Fidelity FBTC need to weigh the higher expense ratio against the embedded tax basis many long-term holders accumulated when GBTC was the only regulated option. Grayscale also operates a separate lower-fee Bitcoin product (BTC, the Grayscale Bitcoin Mini Trust) for investors who want to stay with the issuer at lower cost.
GBTC is Grayscale's spot Bitcoin ETF, converted from a closed-end trust on January 11, 2024. It is one of the oldest regulated US Bitcoin investment vehicles and trades on NYSE Arca.
GBTC's 1.5% expense ratio is a legacy of its closed-end trust structure, which historically had less competitive pressure. After the spot ETF approval, newer entrants like IBIT and FBTC launched at 0.25%, putting fee pressure on GBTC. Grayscale has since launched a lower-fee Mini Trust to retain price-sensitive investors.
Outflows reflect rotation: long-term holders who acquired GBTC when it was the only regulated option are selling to move into cheaper products like IBIT and FBTC, or to take profits. The trust still holds a top-three share of US spot Bitcoin ETF AUM despite the rotation.
Grayscale converted its Ethereum Trust (ETHE) to a spot Ethereum ETF in July 2024. ETHE is older and higher-fee than competitors, with the same Mini Trust pattern Grayscale used for Bitcoin to retain fee-sensitive investors.
