According to Eric Balchunas, the process of creating exchange-traded funds (ETFs) for newer altcoins that lack futures contracts, such as Bonk and Trump coin, would necessitate using the 40 Act and the $SSK Maneuver, resulting in a different ETF structure. He notes that historically, the 33 Act is preferred for spot ETFs due to its direct exposure to the underlying asset. Traders should monitor regulatory developments closely, as these structures could impact the accessibility and liquidity for altcoin ETFs in the crypto market (source: Eric Balchunas).
