When the Fund stakes Ether, Ether is subject to the risks attendant to staking generally. Staking requires that the Fund lock up Ether for the period of time required by the staking protocol, meaning that the Fund cannot sell or transfer the staked Ether, thereby making it illiquid for the period it is being staked. In addition, during the lock-up period, the Fund is subject to the market price volatility of Ether, and it may miss opportunities to sell the staked Ether during opportune times. During the unstaking period, the Fund may miss out on earning opportunities because, in some cases, the staked Ether may not earn rewards during the unstaking period or may only earn rewards during part of the unstaking period. Staked Ether is also subject to security breaches, network downtime or attacks, smart contract vulnerabilities, and validator or custodian failure or compromise, which can result in a complete loss of the staked Ether or a loss of any rewards. Staking rewards are not reflective of returns at the fund level. Potential staking rewards are earned by the Fund and not paid directly to investors. *Low-fee based on gross expense ratio at 0.15%. Brokerage fees and other expenses may still apply.
