Hong Kong Bitcoin and Ether exchange-traded funds (ETFs) will differ significantly from their United States counterparts, as the city's regulator has approved them for launch on April 30. According to a report by one of the issuers, ChinaAMC, its spot Bitcoin and Ether ETFs will track the performance of the Chicago Mercantile Exchange's crypto indices. Redemptions will be available in both fiat currency and crypto deposits.
