Grayscale Investments, the world's largest digital currency asset manager, recently deposited 6,068 ETH, worth approximately $15.89 million, to Coinbase Prime, a prime brokerage service for institutional investors. The transaction was made from a Grayscale-linked address to a Coinbase Prime address and was identified by Arkham Intelligence, an on-chain analysis firm. Grayscale's move to deposit a significant amount of ETH to Coinbase Prime suggests that the company may be preparing to offer new products or services related to ETH or other digital assets. Coinbase Prime provides a range of services to institutional investors, including custody, trading, and lending. By depositing ETH to Coinbase Prime, Grayscale can access these services and potentially offer them to its clients. The transaction also highlights the growing institutional interest in digital assets. As more institutions enter the digital asset market, the demand for services like those offered by Coinbase Prime is likely to increase.
