According to @EmberCN, US ETH spot ETFs now allow staking, and two ETH spot ETFs managed by Grayscale staked 32,000 ETH over the past 9 hours using 10 addresses, following a prior distribution 20 days ago of 3,200 ETH per address that was described as preparation for staking. According to @EmberCN, Grayscale announced last night that the ETFs it manages can stake ETH, and the Arkham Intelligence entity page for Grayscale is cited for the related on-chain activity. According to @EmberCN, this development is cited as a possible contributor to ETH rebounding from $3,800 to $4,700.
