Robinhood currently holds over 1.2 million ETH, accounting for about 1% of Ethereum's total supply, making it one of the major holding addresses on-chain. It has become a key gateway for U.S. retail investors to enter the cryptocurrency space, with many users tending to hold ETH long-term or trade infrequently after purchasing. In the future, Robinhood has the potential to become one of the most important ETH trading gateways for Western retail investors, especially in terms of compliance and user experience.
