Bitcoin exchange-traded funds, which were finally introduced earlier this year after intense regulatory scrutiny, have already become some of the most successful ETF launches ever. For months it seemed that spot ETFs for Ether, the second-largest cryptocurrency, might linger in a similar purgatory — and then, after some back and forth with issuers, regulators finally blessed them. About 10 products began trading in mid-July; they've seen healthy inflows, though Bitcoin ETFs were in a different league. On this episode of Trillions, Eric Balchunas and Joel Weber welcome stacy-marie ishmael, an executive editor at Bloomberg News who oversees crypto, digital payments and cross-asset coverage, to the podcast. They discuss the differences between Bitcoin and Ether, what happened during the approval process, how the various Ether ETFs compare, what we've learned since their launch, and what this might mean for future crypto ETFs.
