Grayscale Ethereum Trust faces a 'comparative disadvantage' due to the lack of staking, according to a recent SEC filing. The company highlighted the risks associated with Ethereum staking restrictions in its latest disclosure. Grayscale's strategy for its Ethereum Trust could be significantly impacted by these staking limitations. Additionally, the discount on Grayscale Ethereum Trust has decreased from nearly 50% to 1.5% over the past year, with a notable reduction from over 20% following a 'surprise pivot by SEC' in mid-May.
