Grayscale Investments has taken a significant step towards expanding its crypto ETF offerings by registering entities for Cardano (ADA) and Hedera Hashgraph (HBAR) ETFs in Delaware, USA. This move, reported by Unfolded, signals Grayscale's intention to potentially launch exchange-traded funds based on these altcoins. The entity registration in Delaware is a preliminary step, and further regulatory approvals are required before the ETFs can be offered to the public. However, this development suggests growing institutional interest in ADA and HBAR, potentially opening these cryptocurrencies to a wider range of investors through a familiar and regulated investment vehicle. The ETFs could provide easier access and diversification opportunities within the cryptocurrency market. Grayscale's move underscores the ongoing evolution of the crypto investment landscape. ```
