According to ChainCatcher, on-chain analyst Yu Jin monitored that two ETH spot ETFs managed by Grayscale staked an additional 272,000 ETH (1.21 billions USD) four hours ago. Since being allowed to stake, they have deposited a total of 304,000 ETH into staking.
Currently, there are a total of 489,000 ETH waiting to be staked, which means Grayscale accounts for the majority of ETH pending staking activation. However, compared to the amount entering staking, there is much more ETH exiting: at present, a total of 2.427 millions ETH are queued and waiting to exit staking.
