CONCENTRATION OF RISK
 
The Fund holds only ether and cash, which creates a concentration risk associated with fluctuations in the price of ether. Accordingly, a decline in the price of ether will have an adverse effect on the value of the Shares of the Fund. The trading prices of ether have experienced extreme volatility in recent periods and may continue to fluctuate significantly. Extreme volatility in the future, including substantial, sustained, or rapid declines in the trading prices of ether, could have a material adverse effect on the value of the Shares and the Shares could lose all or substantially all of their value. Factors adversely impacting the value of ether and the Shares may include an increase in the global ether supply or a decrease in global ether demand; market conditions of, and overall sentiment towards, the digital assets and blockchain technology industry; trading activity on digital asset platforms, which, in many cases, may be unregulated or subject to regulation by a relevant jurisdiction but potentially non-compliant with such regulations or may be subject to manipulation; the adoption of ether as a medium of exchange, store-of-value or other consumptive asset and the maintenance and development of the open-source software protocol of the Ethereum network, and their ability to meet user demands; manipulative trading activity on digital asset platforms; and forks in the Ethereum network, among other things.
