Quotes that support claims

The options apply specifically to ETHA, meaning that BlackRock’s product is the only spot ether ETF that options can be traded on.
Other funds are listed on the New York Stock Exchange’s Arca and Cboe. Cboe has also filed an application to list options on the ETFs it lists.
