Grayscale Investments is one of the world's largest and most established digital currency asset managers. The firm is renowned for creating the Grayscale Bitcoin Trust (GBTC), which launched in 2013 and for many years served as the primary on-ramp for investors to gain exposure to Bitcoin in traditional brokerage accounts. After a landmark legal victory against the U.S. Securities and Exchange Commission (SEC), Grayscale successfully converted its flagship GBTC fund into a spot Bitcoin ETF in January 2024. As the manager of numerous single-asset investment products, Grayscale custodies billions of dollars in crypto assets. The daily inflows and, more notably, outflows from its wallets are a critical indicator of market sentiment and capital rotation within the digital asset class.
