The prospect of a US approval of Ether exchange-traded funds (ETFs) is raising concerns about exacerbating the Ethereum ecosystem’s concentration problem, according to S&P Global. This issue arises from the potential for staked tokens to remain in the hands of a few providers. The concern follows the approval of the first spot Bitcoin ETFs in January, with investors now anticipating Ethereum’s native token to be next. Applications for spot Ether ETFs, particularly from ARK Investment Management and Franklin Templeton, propose allowing staking, where Ether holders lock their tokens to the Ethereum network to help validate transactions and earn additional yields.
